Sulfur acid-resistant concrete and production process thereof
The invention discloses sulfur acid-resistant concrete and a production process thereof. The sulfur acid-resistant concrete is prepared from the following raw materials in parts by weight: 200 to 300 parts of cement, 40 to 60 parts of fly ash, 160 to 180 parts of water glass, 60 to 80 parts of sodium fluosilicate, 70 to 90 parts of sulfur, 20 to 30 parts of iron ore powder, 200 to 260 parts of quartz powder, 5 to 9 parts of diabase powder, 15 to 25 parts of feldspar powder, 5 to 8 parts of water reducing agent, 4.2 to 6.3 parts of synergist and 80 to 90 parts of water. The concrete is novel in design, the CTF synergist, the LBD synergist and the water reducing agent are added into the concrete, inorganic insoluble particles, nano silicon dioxide and nano titanium dioxide in the concrete can be better dispersed, a layer of protective film is further generated, permeation of corrosive substances is effectively reduced, the acid and alkali resistance of the concrete is improved, the added sulfur, diabase powder, feldspar powder and iron ore powder are matched with one another so that the acid resistance and the practicability of the concrete can be effectively improved.
本发明公开了一种硫磺耐酸混凝土及其生产工艺，所述硫磺耐酸混凝土包括以下重量份的原料：水泥200‑300份、粉煤灰40‑60份、水玻璃160‑180份、氟硅酸钠60‑80份、硫磺70‑90份、铁矿粉20‑30份、石英粉200‑260份、辉绿岩粉5‑9份、长石粉15‑25份、减水剂5‑8份、增效剂4.2‑6.3份、水80‑90份。本发明设计新颖，通过在混凝土中添加CTF增效剂、LBD增效剂及减水剂，能够更好的分散混凝土中无机不溶颗粒，纳米二氧化硅和纳米二氧化钛还生成一层保护膜，有效减少腐蚀性物质的渗入，提高混凝土的耐酸碱性，添加的硫磺、辉绿岩粉、长石粉及铁矿粉相互配合可有效提高混凝土的耐酸性，实用性。
