“…Clay was obtained from Galadimawa area in Federal Capital Territory; Abuja, Nigeria with a Global Positioning System (GPS) coordinates of 9 • 4 0.0012" N and 7 • 28 59.9988" E at 491 m above sea level. The clay used in this study has been previously characterised in an earlier work by Ngayakamo et al [14], where it was shown that the mineral composition is dominated by kaolinite (Al 2 Si 2 O 5 (OH) 4 ), muscovite (KF) 2 (Al 2 O 3 ) 3 (SiO 2 ) 6 , phengite (K(AlMg) 2 (OH) 2 (SiAl) 10 O 10 ) group of micas and haematite (Fe 2 O 3 ). While the chemical composition of the clay soil mainly consists of 66.10-67.12% silica (SiO 2 ) and alumina (Al 2 O 3 ) between 14.93-19.45.…”

“…The escalating cost of construction materials and dependence on imported building materials have been top on the list of constraints towards provision of adequate housing [7]. One of the ways to tackle this problem is by promoting the development and utilisation of sustainable low-cost materials through usage of earth-based materials (clay), agro-wastes and polymers [8][9][10][11][12][13][14][15]. Research efforts in the use of earth-based materials, agro-wastes and polymers are used to drive the current global shift towards a circular economy where materials are utilised and reused with no waste [16,17].…”

This study investigates the feasibility of creating a clay polymer-based composite using cowpea husk (CPH) as filler for production of roof tiles. Polymeric composites were fabricated by mixing unsaturated polyester (UPT) resin with cowpea husk at different filler weights and curing. A hybrid composite was produced with the addition of 3 wt.% clay and all samples produced were subjected to flexural, hardness and dynamic mechanical analysis (DMA) tests. The effect of clay addition on the mechanical and thermo-mechanical behaviour of formulated composites was investigated. The morphological analysis of the mono and hybrid system shows a rough and coarse inhomogeneous surface with voids created due to the addition of CPH filler for the mono reinforced and clay uniformly filling the voids that were created by the CPH in the hybrid composite. It is observed that hardness, tensile modulus and flexural modulus of hybrid composites increase with an increase in the CPH contents, while the strength and flexural strength all decrease with filler content. The optimal composition was obtained using Grey relational analysis (GRA) at 18% CPH for both mono and hybrid composite. The results imply that the composite combination can be used in making rooftiles and/or also in applications where low strength is required.

“…With a liquid/cement ratio of 0.55 and a fine/coarse aggregate ratio of 15%, the prepared blocks meet the strength requirements and have good frost resistance [45]. For sintered floor tiles and clay bricks, the addition of granite waste increases the bulk density and mechanical properties [46][47][48]. This is attributable to the densification by liquid-phase sintering and is derived from the low-temperature melting of alkali feldspars in the granite waste.…”

Quarrying and processing of granite produce large amounts of waste residues. Besides being a loss of resources, improper disposal of these wastes results in pollution of the soil, water and air around the dumpsites. The main components of granite waste are quartz, feldspars and a small amount of biotite. Due to its hard and dense texture, high strength, corrosion resistance and wear resistance, granite waste may be recycled into building materials, composite materials and fine ceramics, effectively improving their mechanical properties and durability. By using the flotation process, high value-added products such as potash feldspar and albite may be retrieved from granite waste. Also, granite waste has the potential for application in soil remediation and sewage treatment. This review presents recent advances in granite waste reutilization, and points out the problems associated with its use, and the related countermeasures, indicating the scale of high value-added reutilization of granite waste.

An Experimental and Empirical Study on the Use of Waste Marble Powder in Construction Material

et al. 2021

Marble is currently a commonly used material in the building industry, and environmental degradation is an inevitable consequence of its use. Marble waste occurs during the exploitation of deposits using shooting technologies. The obtained elements most mainly often have an irregular geometry and small dimensions, which excludes their use in the stone industry. There is no systematic way of disposing of these massive mounds of waste, which results in the occurrence of landfills and environmental pollution. To mitigate this problem, an effort was made to incorporate waste marble powder into clay bricks. Different percentage proportions of marble powder were considered as a partial substitute for clay, i.e., 5–30%. A total of 105 samples were prepared in order to assess the performance of the prepared marble clay bricks, i.e., their water absorption, bulk density, apparent porosity, salt resistance, and compressive strength. The obtained bricks were 1.3–19.9% lighter than conventional bricks. The bricks with the addition of 5–20% of marble powder had an adequate compressive strength with regards to the values required by international standards. Their compressive strength and bulk density decreased, while their water absorption capacity and porosity improved with an increased content of marble powder. The obtained empirical equations showed good agreement with the experimental results. The use of waste marble powder in the construction industry not only lowers project costs, but also reduces the likelihood of soil erosion and water contamination. This can be seen to be a crucial factor for economic growth in agricultural production.
