The raw material composition of brick includes (by wt%) fly ash 70-80, lime 7-13, gypsum 0-1.3, cement 0-5 and the rest is aggregate, and the raw material composition of mortar includes fly ash 70-80, lime 7-13, cement 0-5 and the rest is aggregate. Besides, said invention also provides the concrete steps of their production method.

Description

technical field [0001] The invention relates to a building brick and mortar made of fly ash discharged from a power plant and a production method of the brick and mortar. Background technique [0002] So far, the existing building bricks made of fly ash are either complicated in technology and high in production cost, and cannot be popularized and applied, or the strength of the bricks is not high, and cannot be used for the load-bearing walls of high-rise buildings. China No. 89109385.0 patent of invention once disclosed a kind of " non-burning and non-steaming fly ash brick and its preparation method ". According to the inventor, the invention has the characteristics of low requirements for material selection, wide source of raw materials, easy production, less energy consumption and low cost. But in the raw material proportioning of this invention, fly ash only accounts for 55%-65% of raw material gross weight, promptly fly ash consumption does not reach 70% of raw mater...
