Large-volume hydrophobic concrete for bridge pier tower column in plateau area
The invention discloses large-volume hydrophobic concrete for a bridge pier tower column in a plateau area. The large-volume hydrophobic concrete comprises the following raw materials by weight: 250-350kg/m < 3 > of high-crack-resistance low-heat Portland cement; 50-100 kg/m < 3 > of a cement-based hydrophobic material; 5-20 kg/m < 3 > of rice hull ash; 0.3 to 1.5 kg/m < 3 > of carbon nanotubes; broken stone: 1000-1150kg/m < 3 >; machine-made sand: 700-850 kg/m < 3 >; 0.5-1.5 kg/m < 3 > of a powdery polycarboxylate superplasticizer; and 130-160 kg/m < 3 > of water. The large-volume hydrophobic concrete is prepared from the high-crack-resistance low-heat Portland cement, the cement-based hydrophobic material, the rice hull ash and the carbon nanotubes, so that the dry shrinkage of the concrete can be reduced, the crack resistance of the concrete is improved, and the durability of a tower column structure of a bridge pier and abutment in a plateau region is enhanced.
本发明公开了一种高原地区桥梁墩台塔柱用大体积疏水混凝土，包括以下重量的原料：高抗裂低热硅酸盐水泥：250～350kg/m3；水泥基疏水材料：50～100kg/m3；稻壳灰渣：5～20kg/m3；碳纳米管：0.3～1.5kg/m3；碎石：1000～1150kg/m3；机制砂：700～850kg/m3；粉状聚羧酸减水剂：0.5～1.5kg/m3；水：130～160kg/m3。本发明采用高抗裂低热硅酸盐水泥、水泥基疏水材料、稻壳灰渣和碳纳米管制备大体积疏水混凝土，可减少混凝土干缩，提高混凝土抗裂性，增强高原地区桥梁墩台塔柱结构的耐久性。
