Production process of anti-freezing concrete
The invention discloses a production process of anti-freezing concrete. The production process is characterized by comprising the following steps: a, designing a production device; b, preparing the following raw materials in parts by weight: 100 to 120 parts of river sand, 10 to 20 parts of silica fume, 10 to 20 parts of heavy calcium powder, 10 to 20 parts of slag, 30 to 40 parts of cement, 20 to 30 parts of water, 5 to 6 parts of a water reducing agent, 8 to 10 parts of nitrite, 20 to 30 parts of isobutyltriethoxysilane, 10 to 20 parts of hexanediol solution, 20 to 30 parts of starch and 240 to 300 parts of coarse aggregate; c, sequentially adding the river sand, silica fume, heavy calcium powder, slag, cement, water reducing agent, nitrite, isobutyltriethoxysilane, hexanediol solution, starch and coarse aggregate into a screening structure for screening treatment, and feeding the screened materials into a stirring tank through a feeding structure; and d, adding water into the stirring tank, and continuously stirring for 350-420 seconds.
本发明公开一种防冻混凝土的生产工艺，其特征在于包括如下步骤：步骤a、设计一种生产装置；步骤b、按照100‑120份河沙、10‑20份硅灰、10‑20份重钙粉、10‑20份矿渣、30‑40份水泥、20‑30份水、5‑6份减水剂、8‑10份亚硝酸盐、20‑30份异丁基三乙氧基硅、10‑20份己二醇溶液、20‑30份淀粉、240‑300份粗骨料将原料配比好，备料；步骤c、将河沙、硅灰、重钙粉、矿渣、水泥、减水剂、亚硝酸盐、异丁基三乙氧基硅、己二醇溶液、淀粉和粗骨料按顺序加入筛分结构进行筛分处理，筛分后的物料通过上料结构上料至搅拌罐内；步骤d、再将水加入至搅拌罐内进行继续搅拌350‑420s。
