Anti-freezing concrete as well as preparation method and application thereof
The invention relates to anti-freezing concrete as well as a preparation method and application thereof. The anti-freezing concrete is prepared from the following raw materials in parts by weight: 370 to 383 parts of cement, 50 to 62 parts of fly ash, 84 to 96 parts of mineral powder, 240 to 410 parts of natural sand, 360 to 510 parts of machine-made sand, 180 to 200 parts of stones with the particle size of 5 to 10 mm, 800 to 840 parts of stones with the particle size of 5 to 20 mm, 161 to 165 parts of water and 11.3 to 12.5 parts of an additive, the additive is prepared from the following components in percentage by mass: 3.5 to 4.8 percent of polycarboxylate. By optimizing the components of the anti-freezing concrete, the anti-freezing and synergistic effects are achieved, the anti-freezing and thawing performance is greatly improved, and the temperature rise value caused by cement hydration heat is reduced.
本发明涉及一种抗冻混凝土及其制备方法与应用。所述抗冻混凝土包括以下重量份的原料：水泥370～383份、粉煤灰50～62份、矿粉84～96份、天然砂240～410份、机制砂360～510、粒径为5～10mm的石子180～200份、粒径为5～20mm的石子800～840份、水161～165份和外加剂11.3～12.5份；所述外加剂包括如下质量分数的组分：聚羧酸盐3.5～4.8％。通过优化所述抗冻混凝土的组分，抗冻协同增效，大大提高了抗冻融性能，降低了水泥水化热引起的温升值。
