Weight of rebar per cubic meter of concrete. The specific weight also known as Unit Weight, it is physical quantity similar to density defined as weight per unit volume or length. Generally, unit weight of rebar or reinforcement bar measured in kilogram per cubic metre, this will be 7850 kg/m3.

MoreMinimum Reinforcement Ratio. The purpose of the minimum reinforcement ratio is to control cracking and prevent sudden failure by equipping the member with adequate ductility after the loss of concrete's tensile strength due to cracking.. Building construction codes such as ACI 318-19, provides minimum reinforcement ratio for different reinforcement concrete members such as beams and columns.

MoreThe volume proportion in weight turns out to be. Cement : Sand : Aggregate (in Kgs) is 50 kgs : 115 kgs : 209 kgs (by weight) Water required for the mixture = 27.5 kgs. Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum
