of the normal-density aggregates (coarse aggregate, fine aggregate, or both) with comparable amounts of low-density aggregate [12]. Using this approach, concrete densities from 1,842 to 2,370 kg/m3 can be produced to meet specific project requirements [12]. The uncertainties associated with

Nov 26, 2009 · As for concrete itself, the density of concrete of normal weight is about 2,400 kg per cubic meter, or 145 lbs. per cubic foot. The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used.

Jan 01, 2021 · Hence before using pumice aggregate it is soaked in water for 24 h , . Pumice is light coloured or white in colour.
