Polymer reinforced cement-based surface refurbishing mortar
The invention provides polymer reinforced cement-based surface renovation mortar, and relates to the field of mortar. The polymer reinforced cement-based surface renovation mortar comprises the following components in parts by weight: 40-50 parts of ordinary Portland cement, 30-40 parts of high-alumina cement, 10-20 parts of gypsum, 10-20 parts of natural sand, 2-4 parts of an additive, 3-5 partsof hydroxypropyl methyl cellulose, 1-3 parts of lignocellulose and 10-20 parts of silicon dioxide. The preparation process of the polymer reinforced cement-based surface renovation mortar comprises the following steps that: S1, adding 40-50 parts of ordinary Portland cement into a stirring box, and adding 30-40 parts of high-alumina cement at the same time; S2, adding 10-20 parts of natural sand into the materials in the stirring box which are mixed in the step 1, stirring for 3 minutes, adding 2-4 parts of additive, finally adding a proper amount of tap water, stirring for 5 minutes, and making the materials stand still; and S3, after enabling the materials to stand still for 3 minutes in the step 2, adding 10-20 parts of silicon dioxide into the stirring box, and then adding 3-5 parts ofhydroxypropyl methyl cellulose and 1-3 parts of lignocellulose to finally obtain the polymer reinforced mortar.
本发明提供一种聚合物增强水泥基表面翻新砂浆，涉及砂浆领域。该基于一种聚合物增强水泥基表面翻新砂浆，按重量比包括以下成分：普通硅酸盐水泥40‑50份，高铝水泥30‑40份，石膏10‑20份，天然砂10‑20份，外加剂2‑4份，羟丙基甲基纤维素3‑5份，木质纤维素1‑3份，二氧化硅10‑20份；S1：所述将普通硅酸盐水泥40‑50份加入到搅拌箱里面，同时加入高铝水泥30‑40份，S2：然后向步骤一混合之后的搅拌箱里面加入天然砂10‑20份，并且再搅拌3分钟之后加入外加剂2‑4份，最后加入适量的自来水，搅拌5分钟之后静置；S3：在步骤二静置3分钟之后，再向搅拌箱里面加入二氧化硅10‑20份，然后再加入羟丙基甲基纤维素3‑5份，木质纤维素1‑3份，最后得到聚合物增强砂浆。
