Sprayed concrete and preparation method thereof
The invention relates to sprayed concrete and a preparation method thereof.The sprayed concrete is prepared from coarse aggregate, fine aggregate, a cementing material, water and an accelerator, the cementing material is prepared from tailing powder, and the coarse aggregate, the fine aggregate and the tailing powder are obtained through pretreatment of iron tailing waste rock; wherein the content of the coarse aggregate is 40 to 50 parts by weight, the content of the fine aggregate is 30 to 40 parts by weight, the content of the cementing material is 10 to 15 parts by weight, the content of the water is 6 to 9 parts by weight, and the content of the accelerator is 0.5 to 2 parts by weight. The sprayed concrete is prepared from the tailing barren rock, the cementing material, the water and the accelerator as raw materials, and resource utilization of solid wastes such as the tailing barren rock, the metallurgical slag and the desulfurized fly ash is achieved.
本申请涉及一种喷射混凝土及其制备方法，所述喷射混凝土的原料包括：粗骨料、细骨料、胶凝材料、水以及速凝剂，所述胶凝材料的原料包括尾矿粉，所述粗骨料、所述细骨料以及所述尾矿粉由铁尾矿废石预处理得到；其中，以重量份计，所述粗骨料的含量为40份～50份，所述细骨料的含量为30份～40份，所述胶凝材料的含量为10份～15份，所述水的含量为6份～9份，所述速凝剂的含量为0.5份～2份。本申请利用尾矿废石、胶凝材料、水和速凝剂作为原料制作成喷射混凝土，实现了尾矿废石、冶金渣和脱硫灰等固体废弃物的资源化利用。
