Corrosion-resistant and compression-resistant concrete and preparation process thereof
The invention relates to the technical field of concrete preparation, in particular to corrosion-resistant and compression-resistant concrete. The corrosion-resistant compressive concrete is prepared from the following raw materials in parts by weight: 20-70 parts of cement, 10-15 parts of fly ash, 80-90 parts of fine aggregate, 110-125 parts of broken stone, 50-60 parts of stone, 2-5 parts of slag, 85-100 parts of carbonized recycled aggregate, 0.5-1 part of an additive, 0-2 parts of an anti-erosion inhibitor, 1-5 parts of an anti-corrosion rheological agent and 25-55 parts of water. When the concrete is prepared, the carbonized recycled aggregate subjected to accelerated carbonization treatment and the single-doped anti-corrosion rheological agent are adopted, the crushing value of the carbonized recycled aggregate can be optimized through accelerated carbonization treatment, the compression resistance of the carbonized recycled aggregate can be improved, and meanwhile the compactness and the sulfate chemical corrosion resistance of the concrete can be obviously improved through the single-doped anti-corrosion rheological agent; the corrosion resistance of the concrete can be effectively improved, and the service life of the concrete applied to a salt pan environment is prolonged.
本发明涉及混凝土制备技术领域，具体涉及一种耐腐蚀抗压混凝土，所述耐腐蚀抗压混凝土由以下重量份原料制成：水泥20‑70份、粉煤灰10‑15份、细骨料80‑90份、碎石110‑125份、石块50‑60份、矿渣2‑5份、碳化再生骨料85‑100份、外加剂0.5‑1份、抗侵蚀抑制剂0‑2份、防腐流变剂1‑5份和水25‑55份。本发明在制备混凝土时，采用加速碳化处理后的碳化再生骨料及单掺防腐流变剂，加速碳化处理可以优化碳化再生骨料的压碎值，提高其抗压性能，同时单掺防腐流变剂能明显改善混凝土密实度和混凝土抗硫酸盐化学腐蚀性能，可有效提升混凝土的耐腐蚀性能，提升了混凝土在应用至盐田环境下的使用寿命。
