Abstract: Concrete has an amalgamated microstructure which would be very difficult to study its microstructure due to high level of heterogeneity This research intends to produce a Sustainable High performance concrete (SHPC) by replacing conventional concrete materials with sustainable materials. The vital elements of concrete were replaced with sustainable materials which has the ability to improve the mechanical property of concrete and to make the concrete sustainable. Cement was partially substituted with Fly ash (30% and 35%) and Silica fume (7.5 % and 10%) and fine aggregate was wholly substituted with manufactured sand. Coarse aggregate was partially replaced with recycled aggregate taken from the Construction Demolished Waste (CDW) (30% and 40%).Five trial mixes were prepared and casted into cubes. Compressive strength and quantitative analysis of concrete by using XRD Analysis were studied and the obtained results were interrelated with each other based on their composition of minerals elements and strength of SHPC. The comparative study showed a promising result on the SHPC 3 in which the sustainable materials binds to produce a well-built C-S-H gel. The influence of the sustainable materials at optimal range could help to accomplish sustainability in High Performance Concrete.
