Embodiment Construction

[0016] The aerated concrete of the present invention contains 300-350 kg of siliceous material, 160-180 kg of calcareous material and 0.3-0.5 kg of air-generating agent in each cubic meter of concrete, and is characterized in that it also includes ferric iron tetroxide and gypsum, the ferric oxide accounts for 5-10% of the total weight, and the gypsum accounts for 2-3% of the total weight. Ferroferric oxide is the key formula to enhance the compressive strength, which can improve the strength and compressive strength of aerated concrete brickwork. The compressive strength can be increased by 50~80% compared with the compressive strength of bricks without ferric oxide.

[0017] Specifically, the siliceous material includes sandstone, fly ash and calcium silicate, the sandstone accounts for 15% of the total weight of the siliceous material, the fly ash accounts for 80% of the total weight of the siliceous material, silicon Calcium acid accounts for 5% of the total weight of the...

Abstract

The invention relates to an aerated concrete. Each cubic meter of the concrete contains 300 to 350 kg of a siliceous material, 160 to 180 kg of a calcareous material and 0.3 to 0.5 kg of a foaming agent. The aerated concrete is characterized by further comprising ferroferric oxide and gypsum, wherein ferroferric oxide accounts for 5 to 10% of the total weight of the concrete, and the gypsum accounts for 2 to 3% of the total weight. According to the invention, ferroferric oxide is added into a conventional aerated concrete formula, so an aerated concrete brick prepared from the aerated concrete provided by the invention has effectively improved compressive strength, meets requirements of bearing and is a lightweight and anti-compression brick.

Description

[0001] technical field [0002] The invention relates to the technical field of building materials, in particular to aerated concrete. [0003] Background technique [0004] Air-entrained concrete is made of siliceous materials (sand, fly ash and silicon-containing tailings, etc.) , pre-curing, cutting, autoclaving, curing and other processes made of lightweight porous silicate products. Because it contains a large number of uniform and fine pores after being aerated, it is named aerated concrete. It is suitable for filling walls of high-rise buildings and load-bearing walls of low-rise buildings. Non-load-bearing blocks are the most widely produced and used, and the bulk density is generally 500kg / m 3 and 600kg / m 3 , mainly used in the filling wall and partition wall in the structure, without bearing the load; the volume density of the load-bearing block is 700 kg / m 3 and 800kg / m 3 , after special structural treatment in the building to bear the load; the bulk densit...
