Silt brick

Abstract

The invention provides a more economical and energy-saving silt brick. River silt, coal slag and flyash are used as main raw materials, and after the raw materials are sintered, polystyrene foam plastic added with a flame retardant or polyurethane is used for foaming. The brick is of a right-angled hexahedron in appearance, and the brick has an outline the specification of which is basically consistent with the specification of a conventional brick. Compared with the prior ordinary bricks, the silt brick has the characteristics of less sand content, high plasticity, strong bonding force, gooddrying sensitivity, large shrinkage, and the like.

Description

technical field [0001] The invention relates to a brick, especially a mud brick. Background technique [0002] Wujiang City is located in the south of Jiangsu, the southwest of the Yangtze River Delta, and is the center of the Central, Shanghai and Hangzhou Delta. In recent years, the city's economy has developed rapidly, and the scale of urban construction has continued to expand. At the same time, building energy consumption and land resource consumption have also increased rapidly. How to alleviate and solve the real problem of resource shortage and energy shortage is becoming more and more important and urgent. The development and utilization of silt energy-saving bricks according to the local conditions is a desirable move to realize building energy conservation and consumption reduction, and to promote the development of circular economy.
