AbstractAbout AuthorsReferences
The phase composition and properties of cellular concrete produced with the use of a powder and granular gas-forming agent on the basis of aluminum powder of RA20–RA60 brands has been studied. The granular aluminum gas-forming agent has a high content of active aluminum, 88-90%. Granules possess a low degree of dusting and delay of gas emission in the first minutes in comparison with a powder gas-forming agent. Cellular concrete, produced with the use of granules of aluminum powder, has elevated, by 6–10%, values of compressive strength.
