Effect of temperature rising inhibitor (TRI) on the hydration process of cementitious materials containing fly ash and the performance of concrete was investigated. The hydration process of cementitious materials was examined as a function of the contents of fly ash and TRI. The adiabatic temperature rise, mechanical properties and drying shrinkage of concrete derived from the cementitious materials and TRI were also evaluated. According to the hydration heat of the binder pastes, it was revealed that the addition of TRI lowers and delays the exothermic peaks more significantly in the presence of fly ash. The phase composition and microstructure of the hardened paste indicate that TRI mainly inhibits the hydration degree of the cementitious materials in the first 7 days. The presence of TRI slows down the adiabatic temperature rising rate, reduces the early strength of the concrete and increases drying shrinkage of the concrete.

探究了水化热抑制剂(TRI)对水泥-粉煤灰胶凝材料水化过程和混凝土性能的影响。通过改变粉煤灰在胶凝材料中的占比和水化热抑制剂的掺量,观察了胶凝材料的水化过程以及混凝土的绝热温升、力学性能和干燥收缩特性。胶凝材料的水化热测试结果表明,在含有粉煤灰的胶凝材料中,水化热抑制剂降低胶凝材料的放热速率峰值、延后放热峰出现时间的作用更加明显。硬化浆体的相组成和微观结构测试表明,水化热抑制剂对胶凝材料水化程度的抑制主要发生在7 d前。混凝土试验结果表明,水化热抑制剂会放缓混凝土的绝热温升速率,降低粉煤灰混凝土的早期强度并增加干燥收缩。

探究了水化热抑制剂(TRI)对水泥-粉煤灰胶凝材料水化过程和混凝土性能的影响。通过改变粉煤灰在胶凝材料中的占比和水化热抑制剂的掺量,观察了胶凝材料的水化过程以及混凝土的绝热温升、力学性能和干燥收缩特性。胶凝材料的水化热测试结果表明,在含有粉煤灰的胶凝材料中,水化热抑制剂降低胶凝材料的放热速率峰值、延后放热峰出现时间的作用更加明显。硬化浆体的相组成和微观结构测试表明,水化热抑制剂对胶凝材料水化程度的抑制主要发生在7 d前。混凝土试验结果表明,水化热抑制剂会放缓混凝土的绝热温升速率,降低粉煤灰混凝土的早期强度并增加干燥收缩。

Effect of temperature rising inhibitor (TRI) on the hydration process of cementitious materials containing fly ash and the performance of concrete was investigated. The hydration process of cementitious materials was examined as a function of the contents of fly ash and TRI. The adiabatic temperature rise, mechanical properties and drying shrinkage of concrete derived from the cementitious materials and TRI were also evaluated. According to the hydration heat of the binder pastes, it was revealed that the addition of TRI lowers and delays the exothermic peaks more significantly in the presence of fly ash. The phase composition and microstructure of the hardened paste indicate that TRI mainly inhibits the hydration degree of the cementitious materials in the first 7 days. The presence of TRI slows down the adiabatic temperature rising rate, reduces the early strength of the concrete and increases drying shrinkage of the concrete.
