Medium-low-strength chloride ion erosion resistant high-performance concrete and preparation method thereof
The invention discloses medium and low strength chloride ion erosion resistant high performance concrete, which is prepared from the following raw materials by mass: 1 part of cement, 0.2-0.8 part of phosphorus slag, 0.2-0.8 part of limestone powder, 0.5-1.5 parts of water, 3-4 parts of sand, and 5-6 parts of stone, the average particle size of the phosphorus slag is 100-200 [mu] m, and the particle size distribution D50 of the limestone powder is less than or equal to 100 [mu] m. According to the invention, the phosphorus slag with low levigation degree and high average particle size is adopted and has a synergistic effect with the limestone powder, crystal nucleus induction is carried out by utilizing the hydration effect of the limestone powder on the phosphorus slag powder, the hydration reaction of the phosphorus slag powder is accelerated, and meanwhile, by utilizing the grading design of the particle granularity of the limestone powder and the phosphorus slag, the phosphorus slag with good chloride ion penetration resistance and good water resistance is obtained. And the strength meets the requirement. Therefore, energy consumption can be greatly reduced, and waste residues are fully utilized.
本发明公开了一种中低强度抗氯离子侵蚀的高性能混凝土，由以下质量份的各组分为原料制备得到：1份水泥、0.2份～0.8份磷渣、0.2份～0.8份石灰石粉、0.5份～1.5份水、3份～4份砂、5份～6份石，所述磷渣的平均粒径为100‑200μm，所述石灰石粉的粒度分布为D50≤100μm。本发明中采用磨细程度较低的磷渣，平均粒径在较高水平，与石灰石粉协同作用，利用石灰石粉对磷渣粉的水化作用进行晶核诱导，加快了磷渣粉的水化反应，同时利用石灰石粉与磷渣的颗粒粒度的级配设计，获得抗氯离子渗透性能好，强度满足要求的混凝土。这样可以大幅降低能耗，充分利用废渣。
