Corrosion-resistant high-strength concrete and preparation method thereof
The invention discloses corrosion-resistant high-strength concrete which is prepared from the following raw materials in parts by weight: 100-230 parts of ordinary Portland cement, 145-280 parts of sand, 250-530 parts of stones, 65-120 parts of water, 13-30 parts of silicon powder, 15-28 parts of fly ash, 3-8 parts of a polycarboxylate water reducer, 0.5-2.5 parts of butyl methacrylate, 0.3-1.8 parts of aluminum tripolyphosphate, 2.3-6.8 parts of potassium persulfate, 1.8-3.6 parts of glycerol triacetate, 1.4-2.8 parts of precipitated barium sulfate, 1.9-4.2 parts of bauxite, 1.2-1.3 parts ofpolyvinyl alcohol fibers, 4.5-5.5 parts of glass fibers and 1.8-2.2 parts of polyisobutene fibers. The raw materials are reasonably selected, all the components are matched to achieve a synergistic effect, the use amount of Portland cement is reduced, the production cost is effectively reduced, the structure of the concrete can be effectively improved, the integrity and interaction force of a mixture system in the concrete are effectively enhanced, gaps among particles of all the components are reduced, therefore, the total porosity of the concrete is reduced, the concrete is denser, the corrosion of steel bars can be prevented or retarded, the corrosion resistance is stable, and the effect is lasting.
本发明公开了一种耐腐蚀高强度混凝土，其原料按重量份包括以下组分：普通硅酸盐水泥100‑230份，砂145‑280份，石子250‑530份，水65‑120份，硅粉13‑30份，粉煤灰15‑28份，聚羧酸系减水剂3‑8份，甲基丙烯酸丁酯0.5‑2.5份，三聚磷酸铝0.3‑1.8份，过硫酸钾2.3‑6.8份，甘油三醋酸酯1.8‑3.6份，沉淀硫酸钡1.4‑2.8份，铝矾土1.9‑4.2份，聚乙烯醇纤维1.2‑1.3份、玻璃纤维4.5‑5.5份、聚异丁烯纤维1.8‑2.2份。本发明通过合理选用上述原材料，各组分配合具有协同作用，减少硅酸盐水泥的用量，有效降低生产成本，可以有效地改善混凝土的结构，有效地加强了混凝土中的混合料体系的整体性以及相互作用力，减小各组分颗粒之间的空隙，从而减小混凝土总孔隙率，使混凝土更加密实，可阻止或减缓了钢筋腐蚀，抗腐蚀性能稳定且效果持久。
