ABSTRACT

Strength evaluation of agro waste kerbstone with different particle size was the aim of this research work. The scarcity of building materials and the large disposal of waste agricultural material in developing countries has been a serious problem in building and agricultural industries. And because of this, it has now become very important for engineers to find a way to reuse agro waste material as alternative materials for construction. In this project work, quarry dust which is one of the materials used in kerb stone production was replaced at 10% 20% 30% with fine, crushed and uncrushed particles of palm kernel shell. The kerbs were cured for by water for 7 days, 14 days 28 days, At total of 90 kerbstones were produced for testing for compressive strength and water absorption. A decrease in the slump value was noticed as the amount the palm kernel shell increase. But at replacing with 30% of the fine aggregate, the slump value was high. This was so because of the increasing specific surface as a result of increasing the quantity of palm kernels shell. The compressive strength of the 20% replacement showed a stead increase in strength of the period of curing. Samples of0% replacement had a greater compressive strength at 7 days and 14 days of curing for all samples. But at after 28 days of curing, the 10% fine, 10% uncrushed and 20% fine replacement produced a compressive value higher than the control.

ABSTRACT

The study investigated the green practices adopted in public buildings in Nigeria, with particular reference to three star hotels in Abuja. The population of the study was 114 (89 facility managers and 25 registered builders). Two research questions were raised and two hypothesis tested at .05 level of significance guided the study. The instrument for data collection was a 35-items Green Practices in Public Buildings Questionnaire (GPPBQ) developed by the researcher. The questionnaire was validated by three building technology experts in the Department of Industrial and Technology Education, Federal University of Technology Minna, Niger State. A pilot test of the instrument was carried out in Lafia, Nasarawa State. The Cronbach alpha coefficient Method was used to determine the internal consistency of the instrument and 0.92 was obtained as the overall reliability coefficient of the instrument. Data collected was analyzed and Mean and Standard Deviation were used to answer the research questions while Z-test analysis was used to test the hypothesis at .05 level of significance. Findings revealed that some green practices were adopted by three star hotels in Abuja while others were not adopted. Based on these findings therefore, it was recommended among others that governments at all levels should subsidize the cost of green building materials. This is because some green building materials are expensive and this could hinder their adoption in building construction.

ABSTRACT

The high rate of sediment influx into Nigeria dams call for urgent attention. Land use and land cover have been established to have considerable impacts on hydrology and sediment yield. Hence, the study seeks to understand the land use changes upstream Shiroro dam north central Nigeria watershed between the year 1975 and 2013 using Soil and Water Assessment tool Model. (SWAT) Land use and cover changes were evaluated using topographic maps of 1975, 2000 and 2013 respectively, the watershed land use types were reclassified into nine classes. Examination of the three analysis shows that the major human activities that took place in the watershed is the conversion of forest evergreen, range grasses and wetlands mixed to mostly agriculture, urban and other forms of land-use types. Between 1975 and 2000 there was total extinction of 0.03% forest evergreen land.  Range grasses, forest mixed and wetlands forested lost about 23.92%, 2.06% and 3.77% respectively of its percentage watershed to other land use types. While agriculture, wetlands-mixed, water, barren and residential land use types gained 27.81%, 0.18%, 0.53%, 0.02% and 1.25% additional watershed land area respectively within the period under study. The extinction of forest evergreen, reduction in other forest land-use types and conversion of other land use types to agriculture in the study area make the soil susceptible to soil erosion, Thus, leading to sediment influx downstream. Hence, the need for urgent afforestation program and terraced farming to reduces soil erosion problem in the study area.

ABSTRACT

Value management techniques have been successfully applied to all types of construction projects from buildings to offshore oil and gas platforms, and for all types of clients from private industry to governmental organizations worldwide.  One of the Sustainable Development Goals objectives is increasing access to new technologies to support sustainable development; this has lead to the application of value management to residential housing to ensure sustainable development of affordable housing. In Nigeria, access to affordable housing has largely remained an unfulfilled dream to the vast majority most especially, the middle and the lower class of the society. The gap between the need for housing and the capacity to acquire the desired housing type has led to a demand crisis for affordable housing in Nigeria. In this paper, the concept and benefits of the application of Value Management was explored to enhance affordability of sustainable residential housing for civil servants in Nigeria. The quantitative approach employed was to understand the perception on the benefit of the application of value management on residential project in Niger state. This was done by the use of well structured questionnaire.

ABSTRACT

Urban expansion constitutes one of the key agents of landuse change with the impact felt at local, regional and global levels. This study assesses urban encroachment on agricultural land in Lapai Local Government Area of Niger State, Nigeria using Remote Sensing and Geographic Information techniques. Four imageries of LandSat TM 1988, LandSat ETM 1998 LandSat 7 2008 landsat 8 2018 were processed, classified using supervised classification using ArcGIS 10.4 to assess the total spatial loss of agricultural land to urban expansion. The findings revealed that the study area witnessed a significant reduction and increase in agricultural land and built–up respectively. The socio-economic impacts of urban expansion into agricultural land was derived through the administration of questionnaires to people within the study area, the results gotten showed that the area has experienced an unprecedented rate of urbanization and urban encroachment into agricultural lands which has subjected the area to some negative environmental and socio-economic impacts such as a decrease in the average crop yield, though the impacts are not so severe due to the persistence and emergence of agricultural lands in some areas. It is recommended that urban spreading to agriculture land should be controlled as this will have serious repercussions on food security. Urban expansion cannot be stopped, but with proper management and planning it can be directed in a desirable and sustainable way.

ABBAS, ADAM M. (PhD)

Department of Geography, Federal University Kashere, Gombe-State, Nigeria.

ABSTRACT

The role of water resources in the economic development of a nation cannot be overemphasized. It constitutes the most important necessities to man. This study looks at the consequences/effects of the Maga Dam construction in the Republic of Cameroon on the development of the downstream areas of Kala-Balge and Ngala Local Government Areas of Borno State Nigeria. The negative effects result from drying of one of the richest sources of Nigerian rivers draining into the Lake Chad. It is called River El-beid and locally known as Ebeji which also forms the larger part of the border between Nigeria and Republic of Cameroon (along the two LGAs) for more than 400 km until Lake Chad. To arrive at results showing the magnitude of the effects, a household survey was conducted in the area 0-5 kilometers away from the boundary. A total of 150 households were considered for the interview survey. Field observation and in-depth interviews were also conducted on some stake holders. The results indicate that, economic activities such as farming, fishing, livestock, tourism, trade and transport/navigation, boat carving industries as well as problem of border porosity and security of the area and Nigeria at large have been affected, with resultant effect of poverty, forced out migration and social vices. It is recommended that, in order to restore the river to its normal state some of the waters of Surbewel should be channeled by construction of a navigable canal 0to River El-beid which could also be dyked through the assistance of Lake Chad Basin Commission and Chad Basin Development Authority (CBDA).

ABSTRACT

Begging, accepted by many as a profession, has become a permanent feature on major streets in Nigeria especially in northern part of the country. Physically challenged people have been to a large extent erroneously certified by the society as the legitimate people to practice alms begging. Once a person is born with any form of disability, the society particularly in Northern Nigeria ‘graciously and steadily’ nurtures such people to a crookedly destined path of begging. This is wrong. Abled people are frown at and deemed lazy when they are seen begging; the same should apply to all including the physically challenged because there is ability in disability. Higher institutions of learning have a duty to define and set good example on how a civil society should be organized and run. This paper seeks to find out how universities and other institutions of learning with emphasis in Kaduna state university, Kaduna are leading the society to accommodate and bring out the best in all people including the physically challenged through adherence to building regulations and provisions. The phenomenological approach for evaluating problem based learning using case study, survey and observation tools were employed. All classes, lecture theatres, libraries, laboratories and hostels were studied. A check list was used to assess if buildings provided for learning can be effectively used by physically challenged students. The research result clearly shows that in Kaduna State University, Tafawa Belawa way, Kaduna most learning facilities do not adhere to minimum standard in building regulations and provisions for the physically challenged students.

ABSTRACT

The construction industry plays a crucial role in the economy of any nation, and its activities are vital to achieving national socio-economic development goals of providing shelter, infrastructure and employment. However, statements as to the poor sustainability nature of construction projects executed in most developing countries have been made in recent times, and the Nigerian Construction Industry is no exception. This research was carried out to study the most severe factors mitigating implementation of sustainable projects within Nigerian Construction industry. The research instrument used was structured questionnaire designed and administered to construction participants in Nigeria. Ten (10) critical factors mitigating implementation of sustainable projects in the entire construction industry were identified from detail review of past literature and all were used in the questionnaires in order to prioritize the factors in the order of their severity within the construction industry. A Total of fifty five (55) questionnaires were distributed to the  construction participants; 15 each to Clients and Contractors while twenty five (25) to Consultants comprising of five (5) Quantity Surveyors, Five (5) Architects, Five (5) Services Engineers, five (5) Civil Engineers and five (5) project managers.  Thirty nine (39) questionnaires were successfully retrieved representing (71% of the total). The data obtained in the returned questionnaires was used for analysis. Relative importance index method (RII) was used to determine the relative importance indices of the various factors. From the findings made, it was concluded that the major factors mitigating the implementation of sustainable projects in order of their severity are; Lack of government commitment, Lack of owner or developer’s full support for sustainable concepts,  the assumption of additional cost of building projects, Lack of financial incentives for construction participants, budget constraints  among others.

Department of Civil Engineering Technology, School of Engineering, Abubakar Tatari Ali Polytechnic Bauchi, Bauchi State.

ABSTRACT

 Production of cement consumes natural materials leading to environmental concerns in terms of utilization of raw materials and emissions of CO2. Waste materials disposed from industries and or pozzolana materials containing reactive silica or alumina are used in cement. This study investigated the flexural strength of saw dust ash (SDA) concrete containing various percentages of metakaolin (MK) blend concrete. The flexural strength and water absorption of blended concrete were mainly studied. Ordinary Portland cement was replaced with 0%, 5%, 10%, 15% and 20% of metakaolin and 12% constant replacement level of saw dust ash. The beam samples were tested for flexural strength at the curing age of 7days, 14 days, 28 days, 60days, and 90 days.  It was observed that the flexural strength of concrete increases with replacement levels of OPC/SDA-MK at higher curing ages. The flexural strength for MK 20% is 0.049N/mm2 which slightly increased. The flexural strength for MK 0% 5%, 10%, 15% and 20% at 90 days are 0.047, 0.045, 0.048, 0.047, 0.048 and 0.049N/mm2respectively. Water absorption of OPC/SDA-MK concrete up to 20% replacement decreased with the increased of curing ages. Conclusion were made that 12% replacement of cement with saw dust ash SDA and 15% replacement of cement by metakaolin is ad­equate to enjoy maximum benefit of strength gain and also Cement manufacturers could be encouraged to produce cement with SCMs to bring down cost of building constructions and to reduce emission of CO2.

Key words: SDA- saw dust ash, MK- metakaolin, OPC- ordinary Portland cement, SCMs- supplementary cementitious materials, flexural strength, and CO2- carbondi-oxide.

ABSTRACT

The aim of this study was to investigate the effect of rainfall variability in parts of Benue State. CMAP rainfall data were collected using orbiting satellite for the period of 30 years from 1988 to 2017 over Benue State. Data collected were subjected to various statistical analysis which include Coefficient of Variation which was used to determine the rainfall variability and Precipitation Variability Index (PVI) which was used to show the tendency of drought. The result shows that the mean rainfall distribution is normal since the mean annual precipitation is greater than 1000mm. The precipitation Variability Index in all the selected LGAs within the three zones indicates that the tendency of drought is much higher in the Northern zone of the State followed by the West and the South. Vandeikya LGA in the Western zone have Precipitation Variability Index of 19.50% in August which is an indication of least variability of moisture with high rainfall intensity, it is concluded that, in all the zones in Benue State agricultural activities should be carried out during the month of May, hence the Precipitation Variability Index values in April exceeds 30% which is an indication of higher rainfall variability.

Keywords: CMAP, Drought, Moisture, Precipitation, Variability.
