Water-resisting high-strength gypsum-base concrete brick or building block, and producing method thereof

Abstract

The invention relates to a waterproof high-strength gypsum-based concrete brick or building block and a production method thereof. The waterproof high-strength gypsum-based concrete brick or building block mainly contains gypsum-based composite binding agent, coagulation accelerator and filler. The weight proportions of the components are as follows: 10-100% of gypsum-based composite binding agent, 0-6% of coagulation accelerator, 0-90% of filler, 0-1% of early-strength agent, 0-1% of water-reducing agent, 0-6% of lime and 0-15% of gypsum hemihydrate. 80% of the raw materials of the high-strength gypsum-based concrete brick or building block are industrial byproducts, so that the invention reduces the production cost, realizes energy conservation and discharge reduction, avoids the land occupancy and water pollution caused by chemical gypsum, ore slag, coal ash, furnace slag, alkali waste and carbide slag, and protects the environment.

Description

Technical field [0001] The present invention relates to a building wall material, specifically to a water-resistant high-strength gypsum-based concrete brick or block that can replace clay bricks and cement blocks. technical background [0002] Our country is the "kingdom" of the production and use of small clay bricks in the world. In our country's construction industry, the traditional wall material, small solid clay bricks, has a history of more than 2,000 years. No matter from the perspective of resource and energy consumption, land destruction and environmental pollution, these traditional wall materials are unsustainable building materials. For example, firing clay bricks consumes about 1 million acres of land every year. Among them, 20,000 acres of farmland were destroyed to make bricks; there are about 110,000 clay brick and tile companies in the country, covering an area of ​​more than 6 million acres; the annual energy consumption of clay brick production reaches 6...

Problems solved by technology

For example, there are 20 million tons of phosphogypsum, and it is growing at a rate of 15% per year; there are also 4 million tons of desulfurized gypsum produced every year, and more than 20 million tons of desulfurized gypsum will be added every year after 2010; moreover, there is a large amount of fluorine Gypsum, lemon gypsum, borogypsum, titanium gypsum, salt gypsum, etc. Dihydrate gypsum), only a small amount is used for cement additives, and most of them are in a stacked state, which not only occupies a large amount of land, but also pollutes the environment and groundwater resources
