Preparation method of multi-mineral waste composite admixture
The invention discloses a preparation method of a multi-mineral waste composite admixture. The preparation method comprises the following steps of S1, preparing raw materials: slag waste, fly ash and titanium-loaded kaolin, S2, crushing, grinding and screening: crushing and grinding the slag waste and the fly ash by adopting a crusher and a ball mill, and then screening, S3, drying and cooling, specifically, drying and cooling the materials screened out in the step S2, S4, mixing to prepare an admixture: uniformly stirring and mixing the treated slag waste and the titanium-loaded kaolin through a mixer, and S5, preparing concrete. The compound of slag waste, fly ash and titanium-loaded kaolin isadded to the mixer to prepare the admixture, such that the obtained admixture has characteristics of less pores and good fluidity, and the concrete prepared from the admixture can improve the adhesion among the fly ash, the mineral waste and the cement so as to form the compact set cement, and the strength of concrete is improved.
本发明公开了一种多矿物废料复合掺合料制备方法，包括以下步骤：S1.制备原料：矿渣废料、粉煤灰、负载钛高岭土；S2.粉碎研磨筛选：采用破碎机和球磨机对矿渣废料、粉煤灰进行粉碎研磨，然后进行筛选；S3.烘干冷却：对S2中筛选出的物料进行烘干然后冷却；S4.混合制备掺和料：把处理后的矿渣废料、负载钛高岭土通过混合机搅拌混合均匀；S5.制备混凝土。本发明通过将矿渣废料、粉煤灰、高岭土负载钛的复合物，投入拌合机制成掺合料，所得掺合料气孔很少，具有很好的流动性，通过此掺合料制备混凝土，可改善粉煤灰、矿物废料和水泥之间的粘结性，可形成非常密实的水泥石，并提高混凝土的强度。
