The result shows that blended cement mixed with activatory coal gangue powder has high compressive strength , however , with the increase of the admixture of coal gangue powder , flowability of blended cement paste become worse , and the setting time is not obviously affected 結(jié)果表明,摻入經(jīng)活化處理的煤矸石粉配制的混合水泥具有較好的強度性能;隨摻量增加,水泥漿體的流變性能變差,但對凝結(jié)時間并無明顯影響。
The activatory coal gangue powder ( acgp ) , ground cement clinker and natural gypsum are mixed by different ratios to prepare blended cement specimens , and its mortar compressive strength performance , water usage for standard consistency , and flowability of mortar are investigated 摘要將經(jīng)燃燒等過程進行活化處理的煤矸石細(xì)粉與磨至一定比表面積的水泥熟料及天然生石膏混合均勻,制成了活化謀矸石粉摻量比例不同的多組混合水泥,并對其膠砂強度性能、標(biāo)準(zhǔn)稠度用水量、膠砂流動度進行了實驗檢測。
