Multi-element solid waste admixture capable of improving strength of cement concrete and preparation method of multi-element solid waste admixture
The invention relates to the technical field of building materials and industrial solid waste resource utilization, in particular to a multi-element solid waste admixture for improving cement concrete strength and a preparation method of the multi-element solid waste admixture. Three kinds of industrial solid waste including coal gasification slag, coal gangue and zirconium silicon slag are used as raw materials and subjected to activating treatment through a method of ball milling and calcination in sequence; the selected solid waste material contains a large amount of SiO2 in the chemical composition, and the coal gasification slag and the coal gangue contain a large amount of Al2O3, so that the cement admixture has potential volcanic ash activity, and in order to fully excite the potential volcanic ash performance, an activation mode of first ball milling and then calcination is selected for activation, so that the cement admixture is obtained. The novel all-solid waste admixture is obtained and is applied to a mortar material so as to improve the mechanical property of concrete.
本发明涉及建筑材料及工业固废资源化利用技术领域，具体涉及一种提高水泥混凝土强度的多元固废掺合料及其制备方法，本发明以煤气化渣、煤矸石、锆硅渣三种工业固废为原料，通过先球磨后煅烧的方法进行活化处理，随炉降温后形成水泥掺合料，本发明所选用的固废材料在化学组成中都含有大量SiO2，且煤气化渣和煤矸石中含有大量Al2O3，所以具有潜在的火山灰活性，为了使潜在的火山灰性能得到充分激发，选用先球磨再煅烧的活化方式进行活化，得到一种新的全固废掺合料，应用于胶砂材料中以提高混凝土的力学性能。
