Problems solved by technology

At present, titanium gypsum can be used as calcium source and iron source to produce cement, and it can also be used as cement clinker retarder, sintered bricks, etc., but due to geographical restrictions, it cannot achieve the purpose of mass consumption, and most titanium gypsum is still piled in the stockyard
Stockpiling takes up a lot of land area, and it is more likely to pollute groundwater sources after being washed by rainwater

Abstract

The invention discloses titanium extracting tailing-titanium gypsum based foam concrete and a preparation method thereof. The titanium extracting tailing-titanium gypsum based foam concrete is prepared from the following components in parts by weight: 120 to 840 parts of titanium extracting tailings, 120 to 840 parts of titanium gypsum, 4 to 84 parts of type I exciting agent, 0.67 to 17.87 parts of type II exciting agent, 0.8 to 120 parts of coagulant, 20 to 178.7 parts of gel material, 0.4 to 5.9 parts of polycarboxylic acid efficient water reducing agent, 10.7 to 32 parts of physical foamingfoam and 266 to 600 parts of water. The preparation method comprises the following steps: weighing the raw materials according to the weight part ratio; grinding the titanium extracting tailings andthe titanium gypsum; mixing and stirring the raw materials and adding the foam; molding and curing to prepare the titanium extracting tailing-titanium gypsum based foam concrete. The titanium extracting tailing-titanium gypsum based foam concrete disclosed by the invention is a light-weight building material with low carbon emission and is suitable for being used as a heat-preservation and heat-insulation layer of a wall body and a heat-preservation layer of a floor heating system.

Description

technical field [0001] The invention belongs to the concrete composition and its preparation, and relates to a titanium tailings-titanium gypsum-based foam concrete and a preparation method thereof. The titanium tailings-titanium gypsum-based foam concrete of the invention is a lightweight building material with low carbon emissions , suitable for wall insulation and floor heating insulation. Background technique [0002] With the development of housing construction, in some areas with hot summer and cold winter, installing heat insulation layer on the outer wall of the house is the first choice to reduce energy consumption. The heat insulation layer is usually made of organic materials such as polystyrene board and extruded board, but compared with inorganic materials, organic materials have poor high temperature resistance, and the fire performance will be greatly reduced. Therefore, the development of inorganic heat insulation layer with energy saving, heat insulation an...
