Seawater sea sand concrete with chloride ion curing capacity and toughness
The invention relates to seawater sea sand concrete with chloride ion curing capacity and toughness. The seawater sea sand concrete is prepared from the following raw materials in parts by weight: 500 to 600 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, 80 to 90 parts of rubber powder and 0 to 15 parts of water glass, the cementing material is composed of cement and a mineral admixture; the fine aggregate is natural sea sand. The low-price rubber powder is used, the water glass is used for modifying the rubber powder, the compactness of the concrete is enhanced, a chloride ion migration channel is blocked, the activity of a cementing material is stimulated through the water glass, the seawater sea sand concrete is promoted to generate more hydration products in the early stage, the chloride ion curing capacity of the seawater sea sand concrete is improved, and the service life of the seawater sea sand concrete is prolonged. The seawater sea sand concrete disclosed by the invention has excellent toughness and chloride ion curing capacity, also has excellent toughness, and is simple in preparation process and low in cost.
本发明涉及一种兼具氯离子固化能力和韧性的海水海砂混凝土，包括如下重量份的原料：胶凝材料500‑600份，细骨料400‑500份，粗骨料1000‑1100份，海水200‑220份，减水剂3‑6份，橡胶粉80‑90份，水玻璃0‑15份；所述胶凝材料由水泥和矿物掺合料组成；所述细骨料为天然海砂。本发明通过使用价格低廉的橡胶粉，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，促进海水海砂混凝土在早期生成更多水化产物，提高海水海砂混凝土的氯离子的固化能力，本发明的海水海砂混凝土具有优异的韧性和氯离子固化能力，还具有优良的韧性，并且制备工艺简单，成本低。
