Sulphoaluminate cement-based marine concrete and preparation method thereof
The invention provides sulphoaluminate cement-based marine concrete and a preparation method of the sulphoaluminate cement-based marine concrete. The concrete is prepared from the following raw materials in parts by weight: 500-600 parts of sulphoaluminate cement, 200-300 parts of limestone gravel with the particle size of 6-20 mm, 600-800 parts of sea sand with the particle size of 1-5 mm, 100-200 parts of fly ash with the particle size of 0.5-1 mm, 60-120 parts of silica fume with the particle size of 3-8 microns, 30-50 parts of micron calcium carbonate, 20-30 parts of polyacrylic emulsion, 8-14 parts of a reinforcing steel bar corrosion inhibitor, 10-15 parts of an air entraining agent, 5-10 parts of a polycarboxylate water reducing agent and 250-300 parts of water. The sulphoaluminate cement-based marine concrete prepared by the scheme of the invention has the characteristics of excellent strength, durability, corrosion resistance, impermeability and the like, and can be applied to buildings of marine bridges, ports and wharfs.
本发明提供了一种硫铝酸盐水泥基海工混凝土及其制备方法，按照重量份数计，由以下的原料组成：硫铝酸盐水泥500～600份、粒径6～20mm的石灰岩碎石200～300份、粒径1～5mm的海沙600～800份、粒径0.5～1mm的粉煤灰100～200份、粒径3～8μm的硅灰60～120份、微米碳酸钙30～50份、聚丙烯酸乳液20～30份、钢筋缓蚀剂8～14份、引气剂10～15份、聚羧酸盐减水剂5～10份、水250～300份。制备得到了本申请方案的硫铝酸盐水泥基海工混凝土，具有优异的强度、耐久性、抗腐蚀性以及抗渗性等特性，可以应用于海工桥梁、港口、码头的建筑上。
