Concrete weight calculator | volume vs. weight of concrete

The weight of concrete can vary slightly depending on the mix type. The most typical value widely used is 150 lb/ft^3 for the most common/ordinary concrete strength at ~ 4,000 psi = 4000 lbf / (sq in). The aggregate used, strength of concrete and how thin or semi dry the concrete is prepared are the aspects for concrete weight.

Mass Concrete - Portland Cement Association

Mass concrete is defined by the American Concrete Institute as: “any volume of concrete in which a combination of dimensions of the member being cast, the boundary conditions, the characteristics of the concrete mixture, and the ambient conditions can lead to undesirable thermal stresses, cracking, deleterious chemical reactions, or reduction in the long-term strength as a result of elevated ...

How to Calculate Cement, Sand and Coarse Aggregate Quantity ...

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

mass concrete and materials used for mass concrete - Civil ...

The mass Concrete can be defined as ‘Any volume of concrete with dimensions large enough to require measures to be taken to cope with the generation of heat from the hydration of the cement and attendant volume change to minimize cracking’. The mass concreting technique is used for a massive structure such as dams and large bridge piers and foundation. Mass concrete is basically concrete with a higher proportion of coarse aggregate and a lesser proportion of cement, Large size aggregates are pre

Mass Concrete - What is Mass Concrete & Where It Is Used

Nov 22, 2017 · The concrete placed in different massive structures such as dams, bridge piers, canal locks, etc is known as mass concrete. In mass concrete, larger size aggregates (up to 150 mm maximum) and low slump (very stiff consistency) are used to reduce the amount of cement in the concrete mix (normally 5 bags per m3 of mass concrete).

Density of cement concrete. When cement is mixed with sand an aggregate is known as plain cement concrete. For concreting and RCC work like footing, column, beam and slab and for PCC work. Density of cement concrete is 2400 kg/m3, when it is measured in g/cm3,its density is 2.4 g/cm3, in lb/ft3 = 2400×0.0624= 150 lb/ft3 and in kN/m3 is 24.0.
