The effect of coal bottom ash (CBA) on the characteristics of asphaltic concrete was investigated with a view to assess its suitability as a partial replacement of fine aggregate. Coal procured from Lafia-Obi coal mines was burnt in a fixed bed combustor until a sand size residual was produced. The properties of the materials used for the study were characterize using standard procedures. The CBA was introduced in the asphalt mix at an increasing rate of 10, 15, 20 and 25% content by weight of the fine aggregate and test samples of asphaltic concrete were prepared. The samples were subjected to Marshall stability test. Results showed that the specific gravity and absorption test for granite dust were 2.45 and 0.25%, respectively, while those of the CBA were 2.86 and 0.58% respectively. The result of stability, flow, bulk density, voids filled in bitumen (VFB), air voids (VA) and voids in mineral aggregate (VMA) of the asphaltic concrete at 0% CBA were 12.02 kN, 3.04 mm, 2.491g/cm3, 66.0%, 4.3%, 12.7% respectively; while the values at 20% CBA content were 16.97 kN, 3.51mm, 2.514g/ cm3 , 71.2%, 3.4%, 11.9% respectively. The result showed that coal bottom ash in asphaltic mix improved its properties.

In this study, the mechanical properties and durability of rainwater penetration and retention pavement concrete blocks incorporating bottom ash fine aggregate were investigated to develop pavement concrete blocks that could reduce the rainwater leakage of impervious concrete structures. Pavement concrete blocks were prepared by replacing 0%, 10%, and 20% of the weight of natural fine aggregate with bottom ash fine aggregate for 410 and 450 kg/m<sup>3</sup> cement contents. Experimental tests were conducted to determine the compressive strength, flexural strength, abrasion resistance, slip resistance, freeze–thaw resistance, and permeability coefficient of the pavement concrete blocks. Pavement concrete blocks produced with a cement content of 450 kg/m<sup>3</sup> and a 10% replacement ratio of bottom ash fine aggregate satisfied the target performance and exhibited the best overall performance. Theseoptimal mix parameters were applied in this study to design and manufacture pavement concrete blocks for rainwater penetration and retention that satisfied the target performance.

Abstract. To overcome the shortage of natural resources for the production of concrete, many waste materials are used to replace the raw materials of concrete. In this way, bottom ash is one of the major industrial wastes which shall be used as the replacement of materials in concrete production. It shall be used to replace the materials either up to one-third. This review brings out the evaluation of the industrial waste material which can be repeatedly used as a substitution for concrete as fine aggregate. This paper reviewed the use of industrial waste i.e., bottom ash as fine aggregate in the concrete. The parameters discussed were physical, chemical, fresh, and hardened properties of the concrete with partial replacement of bottom ash. By reviewing some of the research papers, concluded that 10-15% replacement of fine aggregates is acceptable for all the properties of concrete. High utilization of natural sources -gives the pathway to produce more industrial wastes which are responsible for the development of new sustainable development.

This study presents an experimental investigation on the recycling of waste incineration bottom ash (IBA) as a fine aggregate in the production of interlocking concrete bricks (ICB). Before being used, the concentration of heavy metal in IBA was determined to confirm it is a non-toxic material. In this study, the IBA was used to replace crushed sand (CSA) in the brick mixtures at different replacement levels of 0%, 25%, 50%, 75%, and 100% (by volume). The ICB samples were checked for dimensions, visible defects, compressive strength, bending strength, water absorption, and surface abrasion in accordance with the related Vietnamese standards. The test results demonstrated that the IBA used in this study was a non-toxic material, which can be widely used for construction activities. All of the ICB samples prepared for this study exhibited a nice shape with consistent dimensions and without any visible defects. The incorporation of IBA in the brick mixtures affected engineering properties of the ICB samples such as a reduction in the compressive strength and bending strength and an increment in water absorption and surface abrasion of the brick samples. As a result, the compressive strength, bending strength, water absorption, and surface abrasion values of ICB samples at 28 days were in the ranges of 20.6 – 34.9 MPa, 3.95 – 6.62 MPa, 3.8 – 7.2%, and 0.132 – 0.187 g/cm2, respectively. Therefore, either partial or full replacement of CSA by IBA, the ICB with grades of M200 – M300 could be produced with satisfying the TCVN 6476:1999 standard in terms of dimensions, visible defects, compressive strength, water absorption, and surface abrasion. These results demonstrated the high applicability of the local IBA in the production of the ICB for various construction application purposes. Keywords: interlocking concrete brick; waste incineration bottom ash; visible defect; compressive strength; bending strength; water absorption; surface abrasion.
