| dc.description.abstract | A huge sum of civil strong waste (MSW) are created each year. The most way of Waste administration and utilization are major concern in numerous parts of the world. Because it may generate power from garbage, burning could be an important process for handling municipal solid waste (MSW). Specifically, municipal solid waste incineration (MSWI) generates two types of ash: bottom ashes (BA) and fly ashes (FA). The lack of space for land fill and the resulting natural pollution is the primary drawback of incineration technology, thus the use of MSWI ash displays a tremendous dedication to waste reduction and asset conservation. This research paper investigated to study the possibility of the Repie waste to energy incinerator plant bottom ash to produce the concrete materials by partial replacement of aggregates in the standards of concrete mix ratio. First the physical and chemical properties of the Repie MSWI BA was investigated in detail and the result obtained with the moisture content of the ash was 30.76wt % having high moisture content. Its particle size distribution was in the range of coarse to fine. The most abundant oxide composition in the bottom ash was found to be SiO2 which reaches up to 48.88%. From the experiment all the three parameters, substitution ratio, particle size and curing time had significant effect on the compressive strength. The optimum condition for maximum CS of 21.21MPa were 10% ratio substitution, with particle size 3.01mm and 28th days curing time for the concrete | en_US |
