摘要

Global warming has affected the planet Earth because of a number of problems. Since cement is the primary ingredient in concrete and has its own environmental issues, the building industry is one of the primary causes. One of the main sources of carbon dioxide is the cement sector. Solid waste disposal, however, is a significant issue. Fly ash, a solid waste product of coal power plants, is challenging to dispose of. In order to address water conservation, environmental impact, and urban resilience, pervious concrete pavers are a crucial component of sustainable urban development. The purpose of this study is to examine the effects of varying the cement content and partially substituting fly ash for cement (between 0% and 50%) in Interlocking Pervious Pavers and the results show that the maximum compressive strength results achieved for 25% of flyash replacement. The addition of fly ash reduces the overall number of voids in fly ash–cement pervious concretes. It is observed that a reduction in total voids results in a 49% increase in compressive strength and a reduction in abrasion.
