环境条件对掺矿物掺合料混凝土硬化性能的影响

Effect of different curing conditions on concrete with mineral admixtures

本文结合江苏地区自然环境温、湿度变化情况,通过大量的实验,研究了环境湿度、环境温度、养护龄期对掺矿物掺合料混凝土的力学性能、收缩变形以及耐久性的影响规律。结果表明:掺矿粉混凝土受环境条件变化的影响较小,而掺粉煤灰混凝土受环境温、湿度变化影响较大,在实际工程应用中应更加重视混凝土养护。

On the basis of test study, the rule was studied how the humidity, temperature and age of curing impact the compressive, strength shrinkage deformation and durability of concrete in this text. The results showed that the smaller impact of changes in environmental conditions in slag concrete, but humidity changes greater impact in fl y ash concrete environmental temperature. In practical engineering, applications should be paid more attention to concrete curing.
