The invention relates to high-performance sea sand concrete with chloride ion curing capacity and a preparation method thereof. The high-performance sea sand concrete is prepared from the following raw materials in parts by weight: 260 to 300 parts of cementing material, 400 to 500 parts of fine aggregate, 1000 to 1100 parts of coarse aggregate, 200 to 220 parts of seawater, 3 to 6 parts of water reducing agent, 1 to 3 parts of defoaming agent, 80 to 90 parts of rubber powder, 0 to 10 parts of water glass, 1 to 2 parts of chloride ion curing agent and 3 to 7 parts of synthetic fiber. The cementing material comprises Portland cement, silica fume and a viscosity-reducing reinforcing agent; the fine aggregate is natural sea sand, and the coarse aggregate is crushed gangue. The water glass is used for modifying the rubber powder, so that the compactness of the concrete is enhanced, a chloride ion migration channel is blocked, the activity of a cementing material is excited through the water glass, the concrete is promoted to generate more hydration products in the early stage, and the chloride ion curing capacity of the concrete is improved; the concrete disclosed by the invention has excellent toughness and chloride ion curing capacity, and is also excellent, simple in preparation process and low in cost.
本发明涉及一种具有氯离子固化能力的高性能海砂混凝土及其制备方法，包括如下重量份的原料：胶凝材料260‑300份，细骨料400‑500份，粗骨料1000‑1100份，海水200‑220份，减水剂3‑6份、消泡剂1‑3份，橡胶粉80‑90份，水玻璃0‑10份，氯离子固化剂1‑2份，合成纤维3‑7份；所述胶凝材料包括硅酸盐水泥、硅灰、降粘增强剂；细骨料为天然海砂，粗骨料为碎矸石。本发明通过利用水玻璃对橡胶粉进行改性，增强混凝土的密实性，阻碍氯离子迁移通道，并且通过水玻璃激发胶凝材料活性，促进混凝土在早期生成更多水化产物，提高混凝土的氯离子的固化能力，本发明的混凝土具有优异的韧性和氯离子固化能力，还具有优良的，并且制备工艺简单，成本低。
