| Abstract: | During construction of Yanzhai hydropower dam,supervision has been carried out on the use of cement,fly ash,coarse and fine aggregate,admixture and water.Especially,research has been focused on the influence of concrete raw material on hydration heat temperature rise and the effect of special concrete on crack prevention.For further understanding of the relation between different concretes and hydration heat temperature rise,the low heat cement concrete has been applied in construction. |
