外加剂对水泥混凝土性能的影响分析

Analysis on Influence of Additive on Performance of Cement Concrete

对掺加了不同外加剂后混凝土的表观密度、凝结时间、泌水率等性能的变化进行了试验研究。结合试验结果,从外加剂的选择、掺量控制等方面,阐述了应用混凝土外加剂时的注意事项,以实现改善混凝土性能,获取预期的技术经济效果的目标。

The changes of performance such as apparent density, setting time and bleeding rate and so on of cement concrete after adding different types of additives were studied by running tests. Combined with the test results, cautions which should be paid attention to while adding the additives to cement concrete were expound- ed in aspects of the choosing of additives and amount control, which is helpful in improving the performance of concrete and so as to acquire expectant economic benefits
