摘要
进行了中低强度自密实混凝土的配制,分析了自密实混凝土的收缩与化学水损失、水泥石水化程度的关系。试验表明:浆体化学结合水与自密实混凝土的收缩之间存在良好的对应关系。随着水泥化学结合水量的增大,自密实混凝土的收缩值也增大。随着粉煤灰掺量的增加,化学结合水量也就相应降低。
The medium strength self-compacting concrete is prepared, analyzing the relationship between the contraction and chemical water loss, the degree of cement hydration.Experiments show that:good relationship exists between slurry chemical combination of water and the contraction of self-compacting concrete.Chemical combination with water of cement increases,the contraction of self-compacting concrete increased.With the increasing in fly ash, chemical combination of water will be reduced accordingly.
