Special impervious concrete for underwater bridge pier and underwater bridge pier poured by using concrete
The invention relates to the field of anti-seepage concrete, and particularly discloses special anti-seepage concrete for an underwater bridge pier and the underwater bridge pier poured with the concrete, and the special anti-seepage concrete for the underwater bridge pier comprises the following components in parts by mass: 240-250 parts of cement, 90-100 parts of mineral powder, 45-55 parts of fly ash, 145-155 parts of water, 720-750 parts of sand, 1050-1060 parts of stone and 5-10 parts of modified sodium abietate. The modified sodium abietate is prepared from the following components in parts by mass: 10 to 12 parts of sodium abietate, 0.8 to 1.2 parts of mussel mucin and 2.5 to 3 parts of bauxite clinker fine powder. According to the invention, the mussel mucoprotein is adopted to modify the sodium abietate, and then the bauxite clinker fine powder is added for grinding, so that the water permeability resistance and chloride ion permeability resistance of the anti-seepage concrete are better, and therefore, the anti-seepage concrete can better adapt to the underwater complex environment when being used as the special anti-seepage concrete for the underwater bridge pier.
本发明涉及抗渗混凝土领域，具体公开了一种水下桥墩专用抗渗混凝土及利用该混凝土浇筑的水下桥墩，水下桥墩专用抗渗混凝土包括以下质量份数的组分：水泥240‑250份、矿粉90‑100份、粉煤灰45‑55份、水145‑155份、砂720‑750份、石1050‑1060份、改性松香酸钠5‑10份；改性松香酸钠由以下质量份数的组分组成：松香酸钠10‑12份、贻贝粘蛋白0.8‑1.2份、铝矾土熟料细粉2.5‑3份。本申请采用贻贝黏蛋白对松香酸钠改性，接着加入铝矾土熟料细粉研磨，使抗渗混凝土的抗水渗透性和抗氯离子渗透性均取得较佳值，因此将上述抗渗混凝土作为水下桥墩专用抗渗混凝土，其能够更好地适应水下的复杂环境。
