Method for preparing building wall block from titanium gypsum

Abstract

The invention discloses a method for preparing a building wall block from titanium gypsum. The building wall block prepared from the titanium gypsum comprises the following raw materials by weight percentage: 50%-70% of the titanium gypsum, 3%-5% of composite reinforced fibers, 30%-35% of cement, 0.6%-0.8% of a water-retaining agent, 23%-25% of tap water, 6%-10% of an alkali activator, 0.1%-0.3% of a retarder, 10%-20% of coal ash and 0.1%-0.2% of a foaming agent. In the method, the composite reinforced fibers are added when the wall block is prepared, and the composite reinforced fibers are acommonly used fibrous reinforcing material; in addition, the composite reinforced fibers is a composite material formed by fiberglass and a basis material by forming processes such as winding, mould pressing or pultrusion and the like, so that the overall strength of the massive wall block can be obviously enhanced, the problems of cracking and the like of the wall block in the transportation andusing processes can be effectively prevented, and the rejection rate of the wall block is reduced.

Description

technical field [0001] The invention relates to the technical field of titanium gypsum processing, in particular to a method for preparing building wall blocks using titanium gypsum. Background technique [0002] Titanium gypsum is an industrial waste residue mainly composed of dihydrate gypsum produced by adding lime to neutralize a large amount of acid wastewater in order to treat acid wastewater when sulfuric acid method is used to produce titanium dioxide. At present, only a small amount of titanium gypsum is used for cementing materials. With the use of admixtures, a large amount of titanium gypsum has not been effectively utilized, and the discharged gypsum needs to be stacked on a large amount of land, which not only wastes cultivated land, but also pollutes the environment. [0003] The wall blocks prepared by the method of preparing building wall blocks from titanium gypsum currently used in the market have low strength, are prone to breakage and damage during trans...
