Anti-freezing dry-mixed mortar and production process thereof
The invention relates to anti-freezing dry-mixed mortar and a production process thereof. The anti-freezing dry-mixed mortar is prepared from the following raw materials in parts by weight: 380-400 parts of fine machine-made sand, 280-300 parts of coarse machine-made sand, 160-180 parts of medium machine-made sand, 140-150 parts of cement, 40-45 parts of scale stone powder, 0.5-1 part of a plastic stabilizer and 0.5-1 part of a mortar anti-freezing agent. The mortar antifreeze agent can effectively reduce the freezing point of concrete and mortar and improve the antifreeze performance of the concrete and mortar at negative temperature. And the early strength of concrete and mortar can be improved by more than 80%, and the later strength is not reduced, so that the strength is also developed under positive, negative and negative temperature conditions, and the effect is remarkable.
本申请涉及一种抗冻型干混砂浆及其生产工艺，由如下重量份的原料组成：细机制砂380份‑400份，粗机制砂280份‑300份，中机制砂160份‑180份，水泥140份‑150份，秤石粉40份‑45份，稳塑剂0.5份‑1份，砂浆抗冻剂0.5份‑1份。砂浆抗冻剂能有效降低混凝土、砂浆的冰点，提高混凝土、砂浆在负温下的抗冻性能。并能使混凝土、砂浆的早期强度提高80%以上，后期强度不降低，从而在正负温和负温条件下强度得到同样发展，效果显著。
