Alkali-activated seawater and sea sand concrete with chloride ion curing capacity and preparation method of alkali-activated seawater and sea sand concrete
The invention discloses alkali-activated seawater and sea sand concrete with chloride ion curing capacity and a preparation method, and relates to the technical field of concrete preparation, the alkali-activated seawater and sea sand concrete comprises the following raw materials by weight: 310-400 parts of a cementing material; 125 to 150 parts of seawater; 1200 to 1300 parts of coarse aggregate; 650 to 750 parts of fine aggregate; 1-5 parts of a naphthalene water reducer; and 0-15 parts of water glass. According to the seawater and sea sand concrete, one or more mineral admixtures are added on the original basis, generation of hydrated calcium silicate gel (C-S-H) and Friedel salt in the concrete is increased, and the curing capacity of the concrete to chloride ions is improved; the alkali activator sodium silicate excites the activity of the mineral admixture to the maximum extent, more hydration products are generated, pores of the concrete are filled, the concrete structure is more compact, invasion of chloride ions is hindered, and meanwhile the solidification capacity of the concrete to the chloride ions is improved through the hydration products.
本发明公开了一种具有氯离子固化能力的碱激发海水海砂混凝土及制备方法，涉及混凝土制备技术领域，包括以下重量份数的原料：胶凝材料310‑400份；海水125‑150份；粗骨料1200‑1300份；细骨料650‑750份；萘系减水剂1‑5份；水玻璃0‑15份。本发明的海水海砂混凝土在原有基础上添加一种或多种矿物掺合料，增加了混凝土中水化硅酸钙凝胶(C‑S‑H)和Friedel盐的生成，提高了混凝土对氯离子的固化能力；碱激发剂水玻璃，最大限度的激发了矿物掺合料的活性，生成量更多了水化产物，填充了混凝土的孔隙，使混凝土结构更为密实，阻碍氯离子的侵入，同时水化产物提高了混凝土对氯离子的固化能力。
