Expanding agent for duct grouting material of prestressed prefabricated part
The invention relates to the technical field of building materials, in particular to an expanding agent for prestressed prefabricated part duct grouting material, which comprises 30-60% of azo compound, 5-20% of alkaline earth metal salt compound, 5-20% of defoaming agent, 8-25% of retarder and 15-50% of admixture, and the sum of the components of azo compound, alkaline earth metal salt compound, defoaming agent, retarder and admixture is 100%. The expanding agent provided by the invention improves the durability of the hardened grouting material, has excellent expansion performance and fluidity, is very simple in mixing process, and is beneficial to improving the labor efficiency.
本发明涉及建筑材料技术领域，具体地说是一种预应力预制构件孔道压浆料用的膨胀剂，包括偶氮类化合物30～60%，碱土金属盐类化合物5～20%，消泡剂5～20%，缓凝剂8～25%，掺合料15～50%，偶氮类化合物、碱土金属盐类化合物、消泡剂、缓凝剂和掺合料的组份之和为100%，本发明的膨胀剂提高硬化后压浆料耐久性，具有优良的膨胀性能和流动性，拌合过程十分简单，有力于提高劳动效率。
