Abstract

The production of ultra-early-strength concrete (UESC) traditionally involves complexity or necessitates hightemperature curing conditions. However, this study aimed to achieve ultra-early-strength performance solely through roomtemperature curing. Experimental results demonstrate that under room-temperature (28
