The invention relates to the technical field of building materials, and particularly discloses a high-resistance concrete material and a preparation method thereof. The concrete material is prepared from the following raw materials in parts by weight: 300 to 400 parts of cement, 30 to 50 parts of silica fume, 50 to 100 parts of heavy calcium powder, 50 to 100 parts of slag powder, 1000 to 1200 parts of broken stone, 700 to 900 parts of sand, 5 to 10 parts of fiber, 0.5 to 1.5 parts of a resistance agent, 0.1 to 1 part of metakaolin, 0.5 to 1.5 parts of a polyurethane waterproof agent and 0.5 to 2 parts of an organic silicon waterproof agent. According to the high-resistance concrete material and the preparation method thereof, by adding the resistance agent, the metakaolin and the polyurethane waterproof agent, the crack resistance and the external sulfate corrosion resistance of concrete are improved, by adding the silica fume, the heavy calcium carbonate powder, the slag powder and the fibers, the compactness and the strength of the concrete are improved, cracks are reduced, and the service life of the concrete is prolonged. The impact resistance of the concrete is enhanced.
本发明涉及建筑材料技术领域，具体公开了一种高抗性混凝土材料及其制备方法，混凝土材料由以下重量份的原料组成：水泥300‑400份、硅灰30‑50份、重钙粉50‑100份、矿渣粉50‑100份、碎石1000‑1200份、砂700‑900份、纤维5‑10份、抗性剂0.5‑1.5份、偏高领土0.1‑1份、聚氨酯防水剂0.5‑1.5份、有机硅防水剂0.5‑2份。本发明采用上述一种高抗性混凝土材料及其制备方法，通过添加抗性剂、偏高领土、聚氨酯防水剂，提升了混凝土的抗裂性能和抵抗外部硫酸盐侵蚀的能力，通过添加硅灰、重钙粉、矿渣粉、纤维，提高了混凝土的密实度和强度，减少了裂缝的产生，增强混凝土的抗冲击能力。
