Light sand-free backfill material for floor heating backfill, and preparation method thereof
The invention relates to the field of building materials, and especially relates to a light sand-free backfill material for floor heating backfill, and a preparation method thereof. The material is composed of 2.5 to 3.5 parts of ordinary Portland cement, 1.5 to 2.5 parts of sulphoaluminate cement, 0.8 to 1.3 parts of gypsum, 0.01 to 0.02 part of a polycarboxylate superplasticizer, 0.01 to 0.03 part of cellulose ether, 0.008 to 0.013 part of a PP fiber, 0.008 to 0.013 part of an early strength agent, 0.03 to 0.05 part of manganese dioxide, 0.3 to 0.5 part of hydrogen peroxide and 3 to 4 partsof water. The method is simple, all the raw materials form the backfill material, and when the material is used for floor heating filling, the quality is stable, and the cost is low.
本发明涉及建筑材料领域，尤其涉及一种用于地暖回填的轻质无砂回填材料及其制备方法，由以下原料组成，普通硅酸盐水泥2.5‑3.5份，硫铝水泥1.5‑2.5份，石膏0.8‑1.3份，聚羧酸减水剂0.01‑0.02份，纤维素醚0.01‑0.03份，PP纤维0.008‑0.013份，早强剂0.008‑0.013份，二氧化锰0.03‑0.05份，双氧水0.3‑0.5份，水3‑4份；本发明工艺简单，各原料组成回填材料，用以地暖填充，质量稳定，成本低。
