The invention discloses environment-friendly anti-crack concrete prepared from foundry waste sand and a preparation process of the environment-friendly anti-crack concrete, and belongs to the technical field of foundry waste sand. The environment-friendly anti-crack concrete comprises an A component raw material and a B component raw material. According to the environment-friendly anti-crack concrete prepared from the foundry waste sand and the preparation process thereof, the problem of environmental pollution caused by stacking and landfill of the precision foundry waste sand is fundamentally solved, the environment-friendly anti-crack concrete becomes a profit point of green manufacturing of an enterprise from the original economic and environment-friendly burden of the foundry industry, and circulating low-carbon economization of the foundry industry is promoted. Besides, solid wastes are adopted as main raw materials, so that consumption of natural minerals in refractory aggregate production is reduced, the prepared refractory aggregate can meet performance indexes, and foundry waste ash and waste sand are utilized at the same time in the preparation process.
本发明公开了一种利用铸造废砂制作的环保型抗裂混凝土及其制作工艺，属于铸造废砂技术领域，包括由A组原料和B组份原料。本发明提出的一种利用铸造废砂制作的环保型抗裂混凝土及其制作工艺，从根本上解决了精密铸造废砂堆放、填埋所带来的环境污染问题，使其从原先铸造行业的经济环保包袱成为企业绿色制造的盈利点，促进铸造行业的循环低碳经济化。另外，由于采用固体废弃物为主要原料，减少了耐火骨料生产对天然矿物的消耗，制得的耐火骨料不仅能满足性能指标，在制备过程中还将铸造废灰和废砂同时利用。
