Low-carbon cement-based microbial concrete and preparation method thereof
The invention provides low-carbon cement-based microbial concrete. The low-carbon cement-based microbial concrete is prepared from the following components in parts by mass: 280 parts of super sulfate cement, 70 parts of II-grade fly ash, 166.4 parts of a microbial solution, 752 parts of sand, 1145 parts of stone, 2.1 parts of a water reducing agent, 0.158 part of an air entraining agent, 4.2 parts of calcium lactate and 1.16 parts of urea. The raw materials of the super sulfate cement are slag, ardealite and the like, the cost is low, industrial by-products can be recycled, the preparation process is simple, the CO2 emission in the preparation process is remarkably reduced compared with that of traditional Portland cement, and the cost is low. After the microorganisms are added, the defect of low early strength of the super sulfate cement concrete can be obviously improved, and the super sulfate cement concrete meets the requirements of actual engineering and is popularized and applied.
本发明提供一种低碳水泥基的微生物混凝土，各组分质量所占份数为：超硫酸盐水泥280份，Ⅱ级粉煤灰70份，微生物溶液166.4份，砂料752份，石料1145份,减水剂2.1份，引气剂0.158份，乳酸钙4.2份，尿素1.16份。本发明中超硫酸盐水泥的原材料为矿渣、磷石膏等，其成本较低，且能够实现工业副产物的再次利用，其制备工序简单，制备过程中的CO2排放量较于传统硅酸盐水泥显著降低，加入微生物后能够明显改善超硫酸盐水泥混凝土早期强度较低的缺陷，使其符合实际工程的要求并推广运用。
