How to Calculate Pounds per Square Foot Concrete Concrete is a composite material of cement, aggregate materials (rocks, gravel, or similar objects), and water Other materials are sometimes added to alter the properties of the concrete These materials could potentially alter the ,...

Answer / bhupinder salwan For converting wet volume of concrete to dry volume of material mix we multiply it by 152 to 154 As water is added in dry material to make it wet concrete and then placed in shuttering particles slides to readjust in pores and voids reducing the volume of it...

of coarse aggregate to concrete for a given maximum size and fineness modulus is given by Table 4 The value from the table multiplied by the dry-rodded unit weight (the oven-dry (OD) weight of coarse aggregate required per cubic foot of concrete) To convert from OD to saturated surface dry (SSD) weights, multiply by [1 + absorption capacity ....

Sep 24, 2019· If you know the density, the mass per unit volume of a material (such as concrete), and the volume of the material, you can multiply the density times volume to determine the mass, and, from there, the weightWhile mass measures an object's amount of matter, weight is the force a planet exerts on an object due to gravity...

Regarding your question on adding more or less water: Contrary to popular belief, concrete doesn't "dry" to for it to cure Concrete hardens as a chemical reaction Adding more water than what is optimal to create the chemical reaction will only weaken the concrete without changing its final weight As a side note, concrete cracks easily...
