Problems solved by technology

At present, most fluorogypsum is directly stacked as a solid waste after a little neutralization treatment, but direct stacking not only occupies land, but also fluorogypsum is acidic, corrodes cultivated land, pollutes water sources, and dust will pollute the air, which is harmful to the environment. great damage

Abstract

The invention relates to a burn-free brick and a production method thereof, particularly to a burn-free brick produced with the Yellow River silt and a production method thereof. The burn-free brick is produced by the extrusion of press machines after mixing the raw materials at a weight ratio as follows: 50-70% Yellow River silt; 20-30% fluoride gypsum powder; 5-10% cement; 3-5% aluminum potassium sulfate and 2-5% construction-used acrylic rubber powder. The invention makes full use of waste fluoride gypsum and a large number of Yellow River silt and is energy-saving and emission reducing and can prevent environmental pollution to meet ecological environmental protection requirements. The burn-free bricks have the advantages of low cost, high strength and good comprehensive performance and each performance are much higher than the relevant national standards of bricks for construction. The production method of has advantages of simple process and convenient production.

Description

technical field [0001] The invention relates to a burn-free brick and a production method thereof, in particular to a burn-free brick made from Yellow River silt and a production method thereof. Background technique [0002] At present, clay bricks are mostly used in buildings in our country, but clay bricks will consume a lot of cultivated land, and the country is restricting the use of clay bricks. [0003] The Yellow River has a high sediment content, and a large amount of sediment enters the sea, causing great waste. In recent years, cities along the Yellow River draw water from the Yellow River, and a lot of Yellow River sediment will accumulate on the banks of the Yellow River. Due to the low viscosity of the Yellow River sediment, the strength of the bricks made cannot meet the building requirements, so it is rarely used for brick making. [0004] Fluorogypsum is an industrial waste produced in the production of hydrogen fluoride in fluoride salt plants, and its mai...
