浅析水泥混合材的复掺与优化

Analysis on the multi-adding of admixture and the optimization

对常用混合材归纳分成三大类,即碱性活性混合材、酸性及中性活性混合材和碱性及中性惰性混合材。在此基础上进行了各类混合材料的复掺试验和分析。结果表明:(1)混合材的碱性和惰性同时具备,有利于早期强度的提高;(2)混合材的酸性与活性同时具备,有利于后期强度的发展;(3)复掺时混合材性质差别越大,越有利于其性能的发挥。最后,对复掺混合材提高水泥强度的作用机理进行了简要的分析。

The common admixtures were classified to three types alkali-reactive admixture, acid-neutral-reactive admixture, alkali-neutral-inactivity admixture, and on that basis the mixing experiment and analysis of all types of admixture were carried out, the results showed as follows： （1） it was benefit for the early strength when the mixture had alkali and inactivity synchronously; （2） it was benefit for the late strength when the mixture had acid and activity synehronouly; （3） more different the property of adding mixtures, more benefit for the performance developing.
