TheseConcrete Calculatorswork out the requiredcementand all-inballastorcement, sharpsandand gravel required to complete a user defined volume of finishedconcrete. Bothconcrete calculatorsmake an allowance for the fact thatballastetc losses volume when mixed to makeconcrete.
So if we need 1 m3 ofconcretein wet condition we have to take consideration of the bulking ofsandand void ratio compressibility for both coarse & fine aggregate (35%+20%) = 55%. Thus every time you need tocalculatethe volume ofconcreteyou need to add the above percentage with dry volume. Wet Volume ofconcrete= Dry Volume ofconcrete+ 55% of dry volume of concrete or. Wet Volume of concrete = Dry …Get Price
