Abstract

The materials for the aerated concrete block include flyash, lime, cement clicker or cement, gypsum, gas former aluminum powder paste, bubble stabilizer active matter or wash powder, and regulator water glass. The block is light and firm, has excellent heat insulating performance, and utilizing flyash as waste can save energy source. Its production process is also provided.

Description

1. Technical field [0001] The invention relates to a silicate block and a production method thereof, in particular to a 300-grade fly ash heat-insulating refractory aerated concrete block and a production method thereof. 2. Background technology [0002] At present, although there are also fly ash aerated concrete blocks, they have a large volume and poor thermal insulation effect, and cannot meet the industrial requirements of lighter thermal insulation materials, better thermal insulation effects, and are not afraid of blisters and fires. This is the prior art. defect. 3. Contents of the invention [0003] The purpose of the present invention is to invent a 300-grade fly ash thermal insulation refractory aerated concrete block and its production method. Utilize the fly ash efficiently, achieve waste utilization, save energy, and have good economic benefits, so as to overcome the deficiencies of the prior art. [0004] The object of the present invention can be achieved...
