Concrete grouting material and preparation method thereof
The invention relates to a concrete grouting material and a preparation method thereof. The concrete grouting material comprises the following raw materials in parts by mass: 40 parts of cement; 60-80 parts of gravel; 20-25 parts of fly ash; 20-30 parts of quartz sand; 10-15 parts of recycled fiber cloth fragments; 2-3 parts of a mixed water reducing agent; wherein the recycled fiber cloth fragments are fragments of cloth formed by at least one of polyester, chinlon, acrylic fibers, polyvinyl chloride fibers and viscose fibers; the mixed water reducing agent is a mixture of a polycarboxylic acid type water reducing agent and a lignosulfonate type water reducing agent, and the mass ratio of the polycarboxylic acid type water reducing agent to the lignosulfonate type water reducing agent is 1: (0.2-0.3). The concrete grouting material can improve the weather resistance of concrete.
本发明涉及一种混凝土灌浆料及其制备方法，该混凝土灌浆料包括以下质量份数的原料：水泥40份；碎石60ˉ80份；粉煤灰20ˉ25份；石英砂20ˉ30份；回收纤维布碎片10ˉ15份；混合减水剂2ˉ3份；其中，所述回收纤维布碎片为涤纶、锦纶、腈纶、氯纶、粘胶纤维中至少一种纤维构成的布料的碎片；所述混合减水剂为聚羧酸系减水剂和木质素磺酸盐类减水剂的混合物，所述聚羧酸系减水剂和所述木质素磺酸盐类减水剂的质量比为1：(0.2ˉ0.3)。该混凝土灌浆料能够改善混凝土的耐候性。
