Bricks and mortar made from fly ash and preparation method

Abstract

The present invention belongs to a building brick made of fly ash, mortar and their production method. 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...

Examples

Embodiment Construction

[0014] The implementation of the present invention is completed on the production line of Xiongying Building Material Factory in Laibin City, Guangxi. The factory's production site is less than 3,000 square meters, the investment is less than 2 million yuan, and the number of employees is less than 25. After the invention is adopted, it can produce more than 30 million fly ash standard bricks per year. The implemented products are mass-produced and sampled by the officials of Guangxi Wall Reform Office, and then sent to the Quality Supervision and Inspection Station of Building Materials Products of the Quality and Technical Supervision Bureau of the Autonomous Region for inspection and commissioned by the National Building Materials Industry Wall and Roofing Materials Quality Supervision, Inspection and Testing Center for inspection. The items all meet the requirements of JC239-2001 "fly ash brick" standard MU15 qualified products and first-class products: the average compress...
