Porous light hollow brick

Abstract

The invention discloses a porous light air brick, which is composed of foam plastic and clay, in which the foam plastic can be a waste packing material hard to be degraded naturally. The proportion of the material is: 20-70% by volume of foam plastic, 80-30% by volume of clay. The process is as follows: blending the materials to make the foam articles distribute uniformly and preparing to the adobe; drying the adobe by natural airiness or sunlight (ensuring the shape maintenance of the adobe during this period); baking the adobe in the kiln after drying; and getting the uneven distributing porous light air brick with different void ratio and void size depending on the difference of the proportion and standard of the foam plastic. The bulk weight, coefficient of heat conductivity, heat-insulating property, loading capacity of the brick changes according to the alteration of the void ratio and void size are obtained.

Description

technical field [0001] The invention belongs to the technical field of building wall heat preservation and energy saving, and in particular relates to a porous lightweight hollow brick. Background technique [0002] Wall building materials require a large amount and are widely used. They are the main materials for building houses, and their weight accounts for about 60% of the total weight of buildings in construction projects. At present, more than 80% of the buildings in our country generally use clay solid bricks, especially in the vast rural areas. Relevant data show that the output of solid clay bricks in my country in 2000 was about 800 billion pieces. Due to the large consumption of raw materials, large volume, high thermal conductivity, and poor thermal insulation performance of clay solid bricks, their mass production and use will bring a series of problems: 1) consume a lot of land (many even cultivated land) resources; 2) firing A large amount of energy is consu...

Problems solved by technology

Due to the large consumption of raw materials, large volume, high thermal conductivity, and poor thermal insulation performance of clay solid bricks, their mass production and use will bring a series of problems: 1) consume a lot of land (many even cultivated land) resources; 2) firing A large amount of energy is consumed in the process; 3) The weight of the building increases, which leads to an increase in the cost of the building foundation and supporting structures; 4
