The invention relates to the technical field of concrete, and discloses sulfate-corrosion-resistant concrete and a preparation method thereof. The concrete comprises the following components in percentage by mass: 20-23% of Portland cement, 15-18% of gravels, 10-15% of natural sand, 8-12% of glass fibers, 5-8% of mineral powder, 5-10 parts of sulfate-resistant composite particles, 1-3% of a polycarboxylate superplasticizer and the balance of water. The preparation method comprises steps: adding Portland cement, gravels and natural sand into a stirrer to be stirred and mixed evenly to obtain apremix; and adding the polycarboxylate superplasticizer into water, stirring and dissolving to obtain a polycarboxylate superplasticizer solution, adding the polycarboxylate superplasticizer solutioninto the premix, carrying out wet mixing, adding glass fibers, mineral powder and the sulfate-resistant composite particles, and continuously stirring and uniformly mixing to obtain the product. The concrete prepared by the invention has excellent sulfate corrosion resistance.
本发明涉及混凝土技术领域，公开了一种耐硫酸盐侵蚀混凝土及其制备方法。包括按质量百分比计的下述组分硅酸盐水泥20‑23%，碎石15‑18%，天然砂10‑15%，玻璃纤维8‑12%，矿粉5‑8%，抗硫酸盐复合粒子5‑10份，聚羧酸减水剂1‑3%，余量为水；将硅酸盐水泥、碎石和天然砂加入搅拌机中搅拌混合均匀，得到预混料；将聚羧酸减水剂加入水中搅拌溶解得到聚羧酸减水剂溶液，将聚羧酸减水剂溶液加入预混合料中进行湿拌，然后加入玻璃纤维、矿粉和抗硫酸盐复合粒子，继续搅拌混合均匀，即得。本发明制备得到混凝土具有优良的耐硫酸盐侵蚀性能。
