The counterweight of heavy concrete is in every respect the featherweight of concrete types: light concrete. The applications speak for themselves: on weak substrates, in situations where light foundations are required, during renovations to existing constructions, etc. But also constructions which, due to their scale or dimensioning, require a low own weight (less than 2000 kg/m3), are formed from light concrete in the same as some civil engineering works concerning road and waterway construction.
This low own weight is achieved by using light aggregates of natural or artificial origin. Volcanic rocks, expanded clay and sintered fly ash grains are good examples. Basal is happy to provide information about the possibilities of light concrete where the combination of prescribed strengths with a lower own weight is important.
