Civil building anti-crack mortar and preparation method thereof
The invention relates to civil building anti-crack mortar and a preparation method thereof. The civil building anti-crack mortar is prepared from the following raw materials in parts by weight: 200 to 350 parts of Portland cement, 400 to 500 parts of machine-made sand, 100 to 200 parts of rubber particles, 50 to 80 parts of composite admixture, 2 to 3 parts of cellulose ether, 5 to 15 parts of redispersible latex powder, 0.1 to 0.3 part of starch ether and 1 to 3 parts of polypropylene fiber. According to the civil building anti-crack mortar, various components are scientifically matched, so that the civil building anti-crack mortar has good comprehensive performance and is short in setting time, high in strength, excellent in alkali resistance, heat resistance and freezing resistance and good in anti-crack effect; according to actual determination of the inventor, the density of the civil building anti-crack mortar is only 1300-1500 kg/m < 3 >, and the civil building anti-crack mortar is light in weight and good in effect; according to the preparation method, the raw materials only need to be mixed and stirred, the process is simple and easy to control, and large-scale production is facilitated.
本发明涉及一种民用建筑抗裂砂浆及其制备方法。所述民用建筑抗裂砂浆，包括如下重量份的原料：硅酸盐水泥200～350份、机制砂400～500份、橡胶颗粒100～200份、复合掺合料50～80份、纤维素醚2～3份、可再分散乳胶粉5～15份、淀粉醚0.1～0.3份和聚丙烯纤维1～3份。所述民用建筑抗裂砂浆，将多种成分进行科学配合，使其具有良好的综合性能，其凝结时间短，强度高，耐碱、耐热、抗冻性优异，抗裂效果好；且经发明人实际测定，所述民用建筑抗裂砂浆密度仅为1300～1500kg/m3，质轻效果佳；所述制备方法，仅需将原料混合后搅拌即可，工艺简单、易控，有利于规模化产出。
