摘要
利用地方材料研制出的PNF流化膨胀剂具有减水、泵送、低掺量、低碱含量、高膨胀率、延滞性微膨胀等特点 ,与优质掺和料一起还可发挥复合迭加效应 ,实现混凝土的高性能化 ,具有补偿收缩、实现混凝土抗裂、防渗、高耐久性的综合功能。
The PNF fluidizing expansive agent developed with local material has characteristics of pumping?lower content?lower alkali?high expansive ratio?and delayed micro-expansion etc.It gives play to compounding overlapping effect with high quality admixture,achieved the high performance of concrete and has comprehensive functions of the shringkage-compensating?crack-resisting? permeation-preventing and high durability.
