Self-leveling repair mortar powder, self-leveling repair mortar, and preparation method and construction process of self-leveling repair mortar
The invention relates to the field of self-leveling repair mortar, and particularly discloses self-leveling repair mortar powder, self-leveling repair mortar and a preparation method and a construction process of the self-leveling repair mortar. The self-leveling repair mortar powder is prepared from the following raw materials in parts by weight: 29.3-35 parts of cement, 2.3-4 parts of silica fume, 2.3-4 parts of an expanding agent, 56-64.1 parts of fine aggregate, 0.3-0.5 parts of a water reducing agent, 0.4-0.8 parts of redispersible latex powder, 0.1-0.4 parts of a coagulation accelerator and 0-0.2 parts of a defoaming agent, The redispersible latex powder is one or more of an ethylene-vinyl acetate copolymer, an acrylate-styrene copolymer and a styrene-butadiene copolymer. The self-leveling repair mortar powder disclosed by the invention can be used for self-leveling repair mortar, so that the prepared self-leveling repair mortar has high fluidity, high tensile adhesive strength, high wear resistance, high compressive strength and high breaking strength, and meets market requirements.
本申请涉及自流平修补砂浆领域，具体公开了自流平修补砂浆粉料、自流平修补砂浆及其制备方法和施工工艺。自流平修补砂浆粉料由包含以下重量份的原料制成：水泥29.3‑35份、硅灰2.3‑4份、膨胀剂2.3‑4份、细骨料56‑64.1份、减水剂0.3‑0.5份、可再分散乳胶粉0.4‑0.8份、促凝剂0.1‑0.4份、消泡剂0‑0.2份，所述可再分散乳胶粉为乙烯‑醋酸乙烯共聚物、丙烯酸酯‑苯乙烯共聚物、苯乙烯‑丁二烯共聚物中的一种或几种。本申请的自流平修补砂浆粉料能够用于自流平修补砂浆，使得制备得到的自流平修补砂浆具有高流动度、高拉伸粘结强度、高耐磨性、高抗压强度、高抗折强度，符合市场需求。
