Abstract

This study involved the optimization of the process for low-temperature early strength polycarboxylate superplasticizers (PCE), and determined the optimal DW07 process with excellent low-temperature early strength performance: n(AA)/n(EPEG) = 9.45, n(TGA)/n(EPEG) = 0.23, n(U1)/n(EPEG) = 0.72, n(M1)/n(EPEG) = 0.36. Additionally, the influence of different pre-curing conditions on the early strength performance of the PCE at low temperatures was investigated. Furthermore, concrete tests were conducted to further validate the strengthening effect of DW07 at low temperatures. The experiments demonstrated that selecting a pre-curing time of 3 h and a pre-curing temperature of 15 ℃ as the optimal pre-curing conditions, the addition of DW07 low-temperature early strength PCE significantly enhanced the 1 d, 3 d, and 28 d strength performance of mortar.
