✦ Synopsis
In this study, we optimized a blend of high-strength, roller-compacted, latex-modified rapid-set concrete (RCLMC) that can be re-opened to traffic after 4 h. To this end, we tested several variables in laboratory experiments, including hardening acceleration agents, cement type, latex addition, and CSA admixture ratios. The target compressive strength was 21 MPa after 4 h. A mixture of Type III cement to CSA admixture at 235:165 kg/m 3 (400 kg/m 3 total binder) and 23.5 kg/m 3 latex (10% of the cement weight) achieved the target compressive strength and was the most economically efficient.
