Concrete admixture
The invention provides a concrete admixture, and relates to the field of general industrial solid waste disposal and resource utilization, in particular to a concrete admixture prepared by taking inorganic wastewater sludge as a raw material. Sludge ash X-ray fluorescence spectrum detection components of the concrete admixture comprises the following components in parts by weight: 20-40 parts of SO3, 30-60 parts of CaO, 5-40 parts of SiO2 + Al2O3, less than 0.1 part of Cl, less than 1 part of K2O + Na2O, less than 10 parts of MgO and less than 10 parts of other components including Fe2O3 + P2O5 and the like. The invention aims to solve the problems of difficult inorganic wastewater sludge landfill site selection, large occupied land, high treatment cost and the like, performs resource utilization while performing reduction and harmlessness, and provides a preparation method of an environment-friendly concrete admixture.
本发明提出了一种混凝土掺合料，涉及一般工业固体废物处置及资源化利用领域，具体涉及以一种无机废水污泥为原料制备混凝土掺合料。一种混凝土掺合料，污泥灰分X射线荧光光谱检测组分为：按重量份计，SO3含量为20～40份、CaO含量为30～60份、SiO2+Al2O3含量为5～40份、Cl含量＜0.1份、K2O+Na2O的含量＜1份、MgO＜10份、包括Fe2O3+P2O5等的其它组分含量＜10份。本发明的目的是解决无机废水污泥填埋选址难、占用土地多、处置成本高等问题，在减量化和无害化的同时进行资源化利用，并提供一种环保型混凝土掺合料的制备方法。
