The air entraining agent used in aerated concrete, mainly activated aluminum powder, reacts with water at a certain temperature and alkaline environment to produce hydrogen. Of course, the active aluminum powder here is specially treated. Because activated aluminum powder will be oxidized and lose its activity in the natural environment. Please don't test without authorization, in case it is unsafe. In practical application, other substances should be added to ensure the uniform distribution of bubbles in the product. Aerated concrete is a new building wall material, which is made of cement, fly ash, lime and foaming agent through mixed reaction and steam autoclaving. The evenly distributed pores inside make this material very light, which can also block sound and has good thermal insulation performance. The most important thing is the technical disclosure of aerated block masonry. It is made of concrete, so it has high strength. Therefore, aerated concrete has the advantages of light weight, high strength, heat preservation, sound insulation and fire prevention. The company produces and sells in large quantities. Consultation telephone number. The initiator component of aerated concrete is aluminum powder, which reacts with alkali to produce a lot of gas. Aerated concrete is characterized by light weight and thermal insulation, and is generally used as wall material, which does not require high strength. The main purpose of inflation is to achieve light weight and heat preservation. [Edit this paragraph] The characteristics of aerated concrete are: light weight, good thermal insulation, good fire resistance, no harmful gas emission, machinability and good sound absorption.
