不同养护条件下内养护补偿收缩砂浆性能研究
Performance of Internal Curing and Shrinkage Compensating Mortar under Different Drying Conditions
摘要
Abstract
Performance of mortar which mixed with high super-absorbent polymer (SAP) and magnesia expansive agent under 28 d drying,wet maintenance 7 d then drying,closed condition were studied.The results show that super-absorbent polymer (SAP) combined with magnesia expansive agent can not only reduce the shrinkage deformation but also improve flexural strength,compressive strength and frost resistance in the above three drying conditions.The influence of the blending on the mortar's properties under varied conditions is different.The shrinkage deformation in close condition is smallest than others;the flexural strength and compressive strength and the frost resistance is the best when the mortar under wet maintenance 7 d then drying condition.The effect of shrinkage reduction is the best,and the strength and frost resistance are higher than that of SAP mortar when mixing magnesia expansive agent and the amount of it is 8％.关键词
