“…It is generally believed that since calcium carbide residue is rich in calcium hydroxide, it behaves like hydrated lime. Hence, calcium carbide residue has also been analysed for potential use as partial replacement for cement in concrete works [13]. A comparison of the results of chemical analysis of the calcium carbide samples tested in Nigeria with those reported by other researchers elsewhere [14,15] and presented in Table 2 shows that there were little but insignificant variations in the chemical compositions.…”

One of the continuing challenges posed by unprecedented urbanisation in Nigeria, estimated at about 5% per annum, is the provision of adequate and affordable housing. The shortage in housing, due in part to the ever-rising prices of construction materials, makes it logical to consider alternative building materials. Paradoxically, Nigeria is grappling with the challenges of managing solid waste, many of which could find suitable applications in the production of cement-, concrete-and clay-based walling, roofing and ceiling products as well as pozzolans for partial replacement for ordinary Portland cement. The objective of this chapter is to present information on the development, experimental investigations and practical application of sustainable building materials from agro-industrial wastes in Nigeria. Agroforestry residues such as bagasse and corn cob ashes have been found suitable as pozzolans; cement-and clay-bonded reinforced composite roofing tiles, hollow concrete blocks and stabilised clay bricks have been developed using a variety of lignocelluloses as sources of fibre reinforcement, while biomaterial substitutes for steel reinforcement in concrete have been tested. However, for these products to become widely acceptable, greater awareness has to be created among all stakeholders in the building construction industry, coupled with the development of appropriate building codes.

“…Agbede and Smart (2007) worked on Makurdi shale and reported high percentage content of mixed-layer illite/smectite responsible for the expansive nature of the soil and recommended a foundation other than the conventional strip foundation. Agbede and Joel (2011) reported the effective stabilization of the Makurdi shale and good bricks quality from heat treatment of natural Makurdi shale treated with carbide waste admixtures.…”

A study was carried out on the cement stabilization of Makurdi shale treated with bamboo leaf ash (BLA), for use as flexible pavement construction material. Classification, Compaction, Consistency, California Bearing Ratio (CBR) and unconfined compressive strength (UCS) tests, were conducted on Makurdi shale specimen treated with Cement and BLA in combined incremental order of 2 % up to 14 % cement, and 4 % up to 20 % BLA of dry weight of soil sample respectively. Results of tests showed that Makurdi shale can be classified as an A-7-6, CH and high swell potential soil by the AASHTO, USCS and NBRRI classification systems respectively. The plasticity index (PI) reduced from 39.4 % for untreated Makurdi shale to 4.7 % at 14 % cement + 20 % BLA. Maximum dry density (MDD) of untreated shale increased from 1.49 Mg/m 3 to a peak value of 1.80 Mg/m 3 at 0 % BLA + 14 % cement. While, the optimum moisture content (OMC) of shale increased from 14.5 % to 33.1 % at 14 % Cement + 20 % BLA. Maximum soaked CBR and 7 day UCS values of 80 % and 1783.9 kN/m² was obtained at 14 % Cement + 20 % BLA. Based on the results of the different tests, the use of Makurdi shale treated with 14 % cement + 20 % BLA are recommended for use as sub-base materials in flexible pavement.

“…Nearly all industrial activities lead to depletion of natural resources, and in the process may result in accumulation of byproduct and/or waste materials. In most areas, the disposals of these waste heaps have become problematic while in recent years there has been concerted effort and intensified research towards the use of these by-products and waste materials in construction (Hughes and Glendinning 2005;Madjo and Riskowiski 2004;Okafor and Okonkwo 2009;Oriola and Moses 2010;Agbede and Joel 2011;Iorliam et al 2012a). Moreover, the proposed use of waste materials from agricultural and industrial activities may as well also help provide solution to waste disposal problems which have arisen from such activities and hence will possibly give rise to a win-win situation both in terms of economics and environmental health.…”

Background: The strength characteristics of two genetically different shales treated with both Rice Husk Ash (RHA) and Coconut Husk Ash (CHA) was evaluated to elucidate responses and effects, examine effectiveness of the additives with a view to ultimately provide economically viable and environmental friendly options for modification and hence stabilization. Methods: 2 to 20 % by weight of both RHA and CHA were separately added to Okitipupa (SW) and Enugu (SE) shales with the subsequent determination of Plasticity Index (PI), Maximum Dry Density (MDD), Optimum Moisture Content (OMC), Unconfined Compressive Strength (UCS) and California Bearing Ratio (CBR). Results: RHA and CHA were found to possess pozolanic properties such that their addition to shale in modest amounts (not more than 10 % by weight) has beneficial effect on the strength characteristics. Addition of RHA produced shales with reduced PI, higher UCS, increased MDD and more pronounced reduction in OMC when compared with the CHA stabilized shales. However in general, addition of 10 % RHA and 6-10 % CHA brought about optimal effect on the geotechnical properties of shales and as such can be regarded as the optimum content. Conclusions: These materials can thus serve as suitable alternatives to modify and stabilize problematic shale and hence help reduce construction costs, environmental hazards and ultimately bring about shales with improved geotechnical properties.
