Abstract
In order to maintain long-term environmental quality, sustainable environmental practices are defined as a system that prevents the exhaustion or degradation of natural assets. By pursuing environmental sustainability, we might assure that the necessary criteria for the present the general populace is content without endangering the potential of upcoming generations to satisfy their private desires. Engineers working in the concrete industry are becoming more and more interested in sustainable development, which includes using locally accessible resources as well as industrial and agricultural left-over in the structure sector being among the probable remedies for the issues with the economy and the environment. After establishing the ideal replacement ratio, this study examined the impact of partial cement replacement with quartz residue (0, 10, 20, and 30%) by weight at several ages on (compressive strength). By means of steam curing for five hours at 90°C after the sample has already hardened, this ideal proportion is utilized to discover its impact on a few properties (like dry density, flexural, and compressive strength) of reactive powder concrete covering 1% recycled copper fibers (RCF). To acquire a compressive strength of 95 MPa next 28 days, reactive powder concrete (RPC) been produced using resident cement, superplasticizer, and silica fume through a W/C proportion of 0.2. The outcomes exhibited that using quartz powder replacing (20%) increased the RPC's compressive strength in 8.5%, flexural strength by means of 9%, dry density in 0.61% at 28 days following comparison of the test grades to the reference mixture.
