Anti-impact wear-resistant concrete for hydraulic engineering and preparation method thereof
The invention discloses impact-resistant and wear-resistant concrete for a water conservancy project. The impact-resistant and wear-resistant concrete is prepared from the following raw materials in parts by weight: 73-81 parts of Portland cement, 41-49 parts of yellow phosphorus slag, 20-30 parts of ardealite powder, 5-10 parts of basophilic bacillus licheniformis, 15-22 parts of brown aluminum oxide, 0.1-0.3 part of polypropylene split film fibers, 3-6 parts of a water reducing agent and 113-129 parts of gravel. The preparation method comprises the following steps: grinding the Portland cement, the yellow phosphorus slag, the brown aluminum oxide and the sandstone to obtain ground powder A; grinding the ground powder A, ardealite powder and polypropylene split film fibers again to obtain ground powder B; calcining the ground powder B at the temperature of 610-630 DEG C to obtain calcined powder; and cooling the calcined powder to normal temperature, doping the basophilic bacillus licheniformis and the water reducing agent, and uniformly stirring. The concrete prepared by the invention is impact-resistant, wear-resistant and long in service life.
本发明公开了一种水利工程用抗冲耐磨混凝土，采用以下重量组分的原料制成：73‑81份硅酸盐水泥，41‑49份的黄磷渣，20‑30份磷石膏粉，5‑10份嗜碱地衣芽孢杆菌，15‑22份棕刚玉，0.1‑0.3份聚丙烯膜裂纤维，3‑6份减水剂，113‑129份砂石。其制备方法为：将硅酸盐水泥、黄磷渣、棕刚玉和砂石进行研磨，得到研磨粉末A；将研磨粉末A与磷石膏粉、聚丙烯膜裂纤维进行再次研磨，得到研磨粉末B；将研磨粉末B进行煅烧，煅烧温度为610‑630℃，得到煅烧粉末；将煅烧粉末冷却至常温，将嗜碱地衣芽孢杆菌和减水剂掺入，并搅拌均匀。本发明制备的混凝土抗冲耐磨，使用寿命长。
