Ultra-high performance concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, and particularly discloses ultra-high performance concrete and a preparation method thereof, the ultra-high performance concrete comprises 80-100 parts of Portland cement, 10-15 parts of silica fume, 70-80 parts of fine aggregate, 60-70 parts of water, 10-15 parts of fly ash, 10-15 parts of a chemical additive, 10-15 parts of a fiber reinforced material, 2-5 parts of silicon dioxide and 0.1-0.2 part of microbial bacteria; by adding microorganisms and inducing mineralization to generate more mineral substances such as carbonate, filling of microcracks in the concrete and improvement of strength are facilitated, chemical reaction in the concrete can be affected and durability can be improved through metabolic activity of the microorganisms, and meanwhile, through combined action of the microorganism-induced mineralization process and ultrasonic treatment, the comprehensive performance of the concrete is improved. The concrete is promoted to be self-healed when tiny cracks occur, the vibration effect of ultrasonic waves is beneficial to tight arrangement of particles in the concrete, the compactness of the concrete is improved, the hydration reaction of cement particles is promoted, and the strength of the concrete is improved.
本发明涉及混凝土制备技术领域，具体公开了一种超高性能混凝土及其制备方法，包括：硅酸盐水泥80～100份、硅灰10～15份、细骨料70～80份、水60～70份、粉煤灰10～15份、化学外加剂10～15份、纤维增强材料10～15份、二氧化硅2～5份和微生物细菌0.1～0.2份；本发明通过添加微生物，诱导矿化过程生成更多的碳酸盐等矿物质，有助于填充混凝土中的微裂缝，提高强度，通过微生物的代谢活动，可以影响混凝土中的化学反应，提高耐久性，同时微生物诱导矿化过程和超声波处理共同作用，促使混凝土在发生微小裂缝时自愈合，超声波的振动作用有助于混凝土中颗粒的紧密排列，改善混凝土的密实性，促进水泥颗粒的水化反应，有助于提高混凝土强度。
