However, the unit weight of concrete increased from 145 pcf to 155 pcf. The tensile strength increased substantially, but should not be considered conclusive (and is elaborated within this dissertation). The modulus of elasticity also improved from 2.5 x 106 psi to 3.2 x 106 psi.;The use of...
Weight of the concrete per volume of concrete. Automatic calculator for the specific unit weight of a volume of concrete in pcf, lb/ft^3, lb/yd^3, kg/m3, fresh wet concrete mix and dry cured hardened concrete. Weighing concrete in tonnes per cubic meter
in particular, has an even lower SG of around 2.32 and very high water absorption of 6.2%. RCA concrete has unit weight in the range of 2240–2320 kg/m3.It has higher water demand and gave lower compressive strength than control concrete made from...

cellular concrete. These air voids are established in the material via the introduction of either a protein-based or synthetic-based foaming agent that reacts mechanically and chemically with the other components to entrap the air and can produce cast density as low as 24 PCF (pounds per cubic...
