Özet
This study examined the effects of various waste materials on the properties of ultra-highperformance concrete (UHPC), along with their designs and ideal mix ratios. Several UHPC mixtures have been developed using the Taguchi L16 method, which generally forms part of the experimental programs for evaluating the properties of UHPCs. Furthermore, the proportions of the component materials were chosen based on approximate ranges found in literature. The samples were cured under two different regimes: standard immersion water curing (SC) and hot water immersion curing (HC). The properties of both hardened and fresh concretes were assessed. A flow test was conducted on the fresh concrete to determine the workability, and a standard test was conducted to assess the density. To investigate a hardened concrete sample, the compressive and flexural strengths were examined and density, absorption, and void tests were conducted. The results obtained from the Taguchi approach for the compressive strength at 28 days were found to be 20 % for SF, 0 % for FA, and 0 % for GBFS; the flexural strength was 10 % for SF, 0 % for FA, and 0 % for GBFS. The compressive strength was 147.07 MPa with SC and 150.13 MPa with HC and flexural strength was 26.88 MPa with SC and 27.31 MPa with HC (as conducted at 28 days in a mixture of 10 % SF and 10 % GBFS).
