A RAW MIX FOR PRODUCING THE POROUS CONCRETE

A RAW MIX FOR PRODUCING THE POROUS CONCRETE

The invention relates to the production of gas-silicate concretes, in particular to the raw mix for producing heat ûinsulated concrete of autoclave production. The raw mix contains, % by weight: 26-32.5 of cement, 18-21.5 of lime, 46-55 of sand, 0.276-0.355 of aluminium powder, 0.0009-0.001 of surfa...

Zusammenfassung:The invention relates to the production of gas-silicate concretes, in particular to the raw mix for producing heat ûinsulated concrete of autoclave production. The raw mix contains, % by weight: 26-32.5 of cement, 18-21.5 of lime, 46-55 of sand, 0.276-0.355 of aluminium powder, 0.0009-0.001 of surface-active substance, water to the value of 0.61-0.66. The porous concrete obtained of the proposed mix is characterized by a mean density of 200-250 kg/m3 and low thermal conduction at high compression strength.
