火山岩石粉复合掺合料研究及对混凝土性能的影响.pdf

建材世界 年 第 卷 第 期
osite admixture of each test age is increasing,and the increase in the ac-
tivity index of the composite mineral powder is more the addition of traditional admixtures of fly ash
and mineral powder,the amount of water-reducing agent shows a downward trend while maintaining the working per-
formance of concrete that is not much with the pure volcanic rock powder concrete group CH0,the
composite with fly ash and mineral powder can significantly improve the compressive strength of concrete,and fly ash
and mineral powder have a prominent superimposing effect.
Key words
: concrete; volcanic rock powder; composite admixture
