Chlorine-salt-corrosion-resistant green concrete and preparation method thereof
The invention belongs to the field of building materials, and relates to a technology for preparing chlorine-salt-corrosion-resistant green concrete by using industrial solid waste. According to the technical scheme, the chlorine-salt-corrosion-resistant green concrete comprises the following components by mass percent: 20-25% of powder, 25-35% of a fine aggregate, 35-45% of coarse aggregate, 8-12% of water, 0.3-0.6% of a water reducing agent and 0.6-1.5% of basalt fiber, wherein the mass percent sum of the components is 100%, the powder comprises the following components in percentage by mass: 50-60% of slag, 15-20% of gypsum, 15-25% of zeolite powder, 8-10% of sodium carbonate and 5.0-10.0% of hydrotalcite, and the sum of the mass percentages of the powder components is 100%. According to the concrete, industrial solid waste is fully utilized, Portland cement is not doped, carbon dioxide emission is reduced, and the concrete is suitable for being applied to areas with high chlorine salt content.
本发明属于建筑材料领域，涉及利用工业固体废弃物制备抗氯盐腐蚀绿色混凝土技术，其技术方案要点是：按照质量百分比由以下组分组成：20~25%粉料；25~35%细骨料；35~45%粗骨料；8~12%水；0.3~0.6%减水剂和0.6~1.5%玄武岩纤维组成，以上各组分的质量百分比之和为100%；其中：所用粉料由以下质量百分比的组分组成：矿渣50~60%，石膏15~20%，沸石粉15~25%，碳酸钠8~10%，水滑石5.0~10.0%，以上各粉料组分的质量百分比之和为100%；该混凝土充分利用工业固体废弃物，不掺加硅酸盐水泥，减轻二氧化碳排放，适于在含氯盐较高的区域应用。
