“…It was also noted that the incorporation of quartz at the proportion between 20 % and 40 % results in flowability reductions of 22 %, 28 %, and 22.5 % for the percentage of SF of 0 %, 15 %, and 30 %, respectively. Althoey et al [ 64 ] developed UHPGPC by incorporating various waste materials into its formulation. They found that the presence of WRP, GW, and MW substantially influenced the flow characteristics of UHPGPC.…”
