High-performance corrosion-resistant concrete for coastal environment and preparation method of high-performance corrosion-resistant concrete
The invention relates to high-performance corrosion-resistant concrete for a coastal environment and a preparation method of the high-performance corrosion-resistant concrete. The concrete comprises the following raw material components in parts by weight: 60-120 parts of cement, 75-140 parts of a concrete corrosion-resistant admixture, 280-350 parts of fine aggregate, 500-600 parts of coarse aggregate, 2-8 parts of a mineral activator, 1-4 parts of a water reducing agent and 50-80 parts of water. According to the concrete, a large-mixing-amount concrete corrosion-resistant admixture is adopted, and the workability and workability of freshly mixed concrete are improved through the micro-aggregate effect of the concrete corrosion-resistant admixture; through the excitation effect of the mineral activator, the pozzolanic activity of the concrete corrosion-resistant admixture is greatly improved, and internal structure gaps of the concrete are filled through the secondary hydration effect of the concrete corrosion-resistant admixture, so that the impermeability and chloride ion permeability resistance of the concrete are improved; and thus, the durability of the concrete, such as sulfate corrosion resistance and freezing resistance, is improved.
本发明涉及一种滨海环境用高性能耐腐蚀混凝土及其制备方法，该混凝土包括如下重量份的原料组分：水泥60～120份，混凝土耐蚀掺合剂75～140份，细骨料280～350份，粗骨料500～600份，矿物激发剂2～8份，减水剂1～4份，水50～80份。该混凝土采用大掺量混凝土耐蚀掺合剂，通过其微集料效应，改善了新拌混凝土的和易性和工作性；由矿物激发剂的激发作用，极大地提高了混凝土耐蚀掺合剂的火山灰活性，通过混凝土耐蚀掺合剂的二次水化作用填充了混凝土内部结构空隙，从而提高了混凝土的抗渗性、抗氯离子渗透性，进而使混凝土的抗硫酸盐侵蚀和抗冻等耐久性能得以提高。
