激发剂在大掺量掺合料混凝土中的试验研究

Experimental research on effect of activator on concrete with high volumn combined mineral admixtures

通过试验对低水泥含量的大掺量复合掺合料混凝土的制备方法进行了分析比较。结果表明:在混凝土中掺粉煤灰和矿渣能取代大量的水泥,同时掺入有效的激发剂和减水剂能够保证混凝土的强度和其它性能,提出了激发剂是开发大掺量复合掺合料混凝土的关键的观点。

The research to analyse and compare the methods of making concrete with low volumn cement and high volumn combined mineral admixtures had made.The results indicated, that more cement in concrete can be replaced with fly ash and slag.Moreover, by adding proper activator and water reducing admixture, the strength and other performances of concrete can be improved greatly.Based on these experimental data, coneluded that the key factor to the development of high volumn combined mineral admixtures is activator.
