High-strength environment-friendly concrete and preparation method thereof
The invention belongs to the technical field of concrete. The invention provides high-strength environment-friendly concrete. The high-strength environment-friendly concrete is prepared from components in parts by mass as follows: 40-60 parts of aluminate cement, 35-50 parts of mineral powder, 0.5-2 parts of metakaolin, 2-5 parts of an additive, 3-8 parts of a fiber material, 2-4 parts of a reinforcing agent, 55-65 parts of gravel, 5-10 parts of nano silicon carbide and 30-50 parts of water. The invention also provides a preparation method of the high-strength environment-friendly concrete. The durability and the strength of the concrete are remarkably improved by reasonably selecting the additive, the fiber material, the reinforcing agent and the plasticizer and reasonably controlling the gradation of the gravel; all the components interact with one another, so that the compressive strength, the breaking strength, the toughness and the impermeability of the concrete are jointly improved, and the concrete has excellent durability and high-temperature stability.
本发明属于混凝土技术领域。本发明提供了一种高强度环保混凝土，包括如下质量份的组分：铝酸盐水泥40～60份、矿粉35～50份、偏高岭土0.5～2份、外加剂2～5份、纤维材料3～8份、增强剂2～4份、砂石55～65份、纳米碳化硅5～10份、水30～50份。本发明还提供了一种高强度环保混凝土的制备方法。本发明通过合理选择外加剂、纤维材料、增强剂和塑化剂，合理控制砂石的级配，显著提高了混凝土的耐久性和强度；本发明的各组分相互作用，共同提高了混凝土的抗压强度、抗折强度、韧性、抗渗性，混凝土具有优异的耐久性和高温稳定性。
