This paper elucidated the temperature dependence of cement setting by comparing the storage modulus (Gʹ) evolutions under different temperatures ranging from 10 to 55 °C. The temperature-induced changes in cement hydration and colloidal interaction were also explored to reveal the underlying physio-chemical effects. It was found that the increase in temperature significantly accelerates the growth of Gʹ in all the stages of setting process, which mainly arises from the promotion of forming “calcium silicate hydrates (C–S–H) bridges” and compressing the electrical double layer of particles. For the same hydration degree, the rise of temperature leads to a greater Gʹ of cement paste. It was attributed to the diminution of the electrostatic repulsive force between particles caused by not only the direct effect of rising temperature but also the higher SO₄^2-/Ca²⁺ concentration ratio of interstitial solution in the paste cured at the higher temperature.

本文通过比较 10 至 55 °C 不同温度下的储能模量 (Gʹ) 演变，阐明了水泥凝固的温度依赖性。还探索了温度引起的水泥水化和胶体相互作用的变化，以揭示潜在的物理化学效应。研究发现，温度升高显着加速了G′在凝固过程的各个阶段的生长，这主要是由于促进了“水合硅酸钙（C-S-H）桥”的形成和压缩了双电层。粒子。对于相同的水化度，温度的升高导致水泥浆体的 Gʹ 更大. 这归因于温度升高的直接影响以及在较高温度下固化的浆料中间隙溶液₄^2-/Ca²⁺浓度比导致颗粒之间的静电排斥力减小。
