摘要
通过试验分析了胶凝材料总量、水胶比、粉煤灰掺量对混凝土干缩性能的影响。结果表明 :在实验范围内 ,胶凝材料总量和水胶比对早期干缩影响较小 ,对后期干缩影响较大 ;
Effects of several factors of binders, including the total amount of binder, water binder ratio and the dosage of fly ash, on drying shrinkage of concrete are discussed in this paper. On conditions of the experiments, the results show that the total amount of binder and water binder ratio have little effects on the early-shrinkage but more effects on the later-shrinkage of concrete, however, the dosage of fly ash influences both the early-shrinkage and later-shrinkage of concrete greatly.
