一乙醇二异丙醇胺对水泥性能的影响试验研究

Experimental study on influence of monoethanol-diisopropanolamine on cementproperties

研究了一乙醇二异丙醇胺(EDIPA)对水泥性能的影响,结果表明:EDIPA在水泥增强和助磨方面的促进作用与TEA、TIPA、DEPA类似,显著提高了水泥28 d抗压强度,增强效果优于TIPA;助磨剂复配中EDIPA掺加比例建议在0.012%~0.014%,搭配其他增加早期强度的原材料使用经济成本相对合算;助磨性能方面略优于TEA、TIPA、DEPA。

The effects of monoethanol-diisopropanolamine(EDIPA)on cement properties were studied.The results showed that EDIPA had similar promoting effects to TEA,TIPA and DEPA on cement strengthening and grinding,which significantly improved the 28-day compressive strength of cement and the strengthening effect was better than TIPA.It is suggested that the proportion of EDIPA in the grinding aids mixture is 0.012%~0.014%,which is relatively cost-effective to use other raw materials to increase the early strength.The grinding performance of EDIPA is slightly better than TEA,TIPA and DEPA.
