High-titanium blast furnace slag high-strength lightweight aggregate and preparation method thereof
The invention discloses a high-titanium blast furnace slag high-strength lightweight aggregate and a preparation method thereof. The high-titanium blast furnace slag high-strength lightweight aggregate is prepared by mixing, by mass, 40%-75% of high-titanium blast furnace slag, 25%-40% of a silicon-aluminum modified component, 3%-8% of an air entraining agent and 2%-12% of a cosolvent. The preparation method comprises the following step of S1, preparing crushed blast furnace slag, a silicon-aluminum modified component, an air entraining agent and a cosolvent. The lightweight aggregate has the beneficial effects that by combining the element composition and structural characteristics of the high-titanium blast furnace slag and optimally designing the mineral composition and structure in the lightweight aggregate finished product, the compressive bearing capacity of the overall structure of the lightweight aggregate is improved, meanwhile, the consumption of the high-titanium blast furnace slag is large, the production process is simple and practical, the comprehensive performance of the obtained lightweight aggregate is remarkably superior to that of ceramsite, the performance requirement of high-strength lightweight aggregate concrete is basically met, and the lightweight aggregate can be used for various large key projects.
本发明公开了一种高钛高炉渣高强轻集料及其制备方法，所述的一种高钛高炉渣高强轻集料，各组分按质量百分比计为，高钛高炉渣40％～75％、硅铝质改性组分25％～40％、引气剂3％～8％和助溶剂2％～12％混合组成，所述的制备方法，包括以下步骤：S1、准备好已经粉碎完毕的高炉渣，以及硅铝质改性组分，引气剂和助熔剂；本发明的有益效果是：本发明结合高钛高炉渣的元素组成和结构特征，对轻集料成品中矿物组成和结构的优化设计，提升了轻集料整体结构的抗压承载能力，同时，高钛高炉渣消耗量大，且生产工艺简单、实用，所得轻集料综合性能显著优于陶粒，基本满足高强轻集料混凝土的性能要求，可以用于各类大型重点工程。
