How To Calculate Compressive Strength Of Concrete Value? – Formula. Compressive Strength of concrete cube = Maximum load/Area of the cube. Example Calculation. Assume that the compression load is 375 KN (1 Kg = 9.81 N) Cross Sectional Area – 15 x 15 = 225 Sqcm. Compressive Strength = (375 x 1000/225) = 1666/9.81 = 169.82 Kg/Sqcm. Lab Report Get price

Reinforced Concrete Design

strength design (also known as limit state design). f' c = concrete compressive design strength at 28 days (units of psi when used in equations) Materials Concrete is a mixture of cement, coarse aggregate, fine aggregate, and water. The cement hydrates with the water to form a binder. The result is a hardened mass with "filler" and pores. Get price

using higher strength concrete. The design methodology based on the idealised short-term (uniaxial) stress-strain diagram, accepted in the Codes for normal strength concrete, can generally be safely applied to higher strength concrete. However, the stress-strain diagrams, may need minor modifications to allow for the lower ultimate strain of HSC. Get price

Properties of Concrete at Elevated Temperatures

In recent years, concrete with a compressive strength in the range of 50 to 120 MPa has become widely available and is referred to as high-strength concrete (HSC).

Water/Cement Ratio

The concrete specimens were made with different water/cement ratios and the applied compressive stress was 0.3 of the 14-day strength. Hence, the creep-time curves are for equality of stress/strength ratio to allow for the strength influence arising from a change in water/cement ratio. Get price
