Titanium slag-based solid waste cementing material and preparation method thereof

Abstract

The invention discloses a titanium slag-based solid waste cementing material and a preparation method thereof. The titanium slag-based solid waste cementing material comprises the following raw materials by weight: 70-80% of a titanium slag-based material, 15-25% of gypsum, and 2.5-7.5% of cement clinker. The preparation method is simple, and the used materials are subjected to separate or mixed grinding according to different types of grindability differences, and then are mixed and stirred. In the raw materials, the titanium-containing slag-based material is used as a main component and is matched with the cement clinker and the gypsum to form the gel material, so that effective comprehensive utilization of a large amount of high-titanium-containing slag and industrial byproduct gypsum resources produced by iron and steel enterprises in Panzhihua, Leshan sand bay and the like in the southwest region can be realized, most of conventional engineering applications can be met, and the material can also be used in a construction environment with rich tunnel terrestrial heat.

Description

technical field

[0001] The invention relates to a titanium slag-based solid waste cementitious material and a preparation method thereof, specifically relates to the preparation of a multi-component synergistic solid waste cementitious material for engineering by using titanium slag and a preparation method thereof, and belongs to the technical field of concrete materials. Background technique

[0002] The main minerals of high titanium slag (hereinafter referred to as titanium slag) are titanium pyroxene, perovskite, bayite, spinel, etc., and the main components are CaO, SiO 2 、TiO 2 、Al 2 o 3 , MgO, whose melt is mainly composed of basic ions Ca 2+ ,Mg 2+ ,O 2- , Ti 2+ , Ti 3+ and complex anion SiO 4 2- ,AlO 4 - , TiO 3 2- Composition, where Ca 2+ The way in which the slag exists has a significant impact on the performance of the slag. Due to TiO 2 Is a very good crystal nucleation agent, Ca in titanium slag 2+ Mainly with TiO 3 2- Form perovskite, unl...
