Method for preparing concrete from cobalt-molybdenum waste catalyst bioleaching residues
The invention relates to a method for preparing concrete by using cobalt-molybdenum waste catalyst bioleaching residues, which comprises the following steps: mixing and stirring cobalt-molybdenum waste catalyst bioleaching residues, cement, standard sand and water, carrying out hydration reaction, and curing to obtain the concrete. The method has the advantages that HW50 hazardous wastes, namely the cobalt-molybdenum waste catalyst bioleaching residues, are used as the concrete admixture, so that the use amount of cement is reduced, the working performance of the concrete is improved, the production cost of the concrete is reduced, and the resource utilization of the wastes is realized.
本发明涉及一种利用钴钼系废催化剂生物沥浸渣制备混凝土的方法，将钴钼系废催化剂生物沥浸渣、水泥、标准砂、水混合搅拌，进行水化反应，固化成混凝土。本发明的优点是：将属于HW50危险废物：钴钼系废催化剂生物沥浸渣，作为混凝土掺合料，减少了水泥用量，在改善混凝土工作性能的同时，降低了混凝土的生产成本，实现废弃物的资源化利用。
