Compressive Strength of Concrete | Cube Test,

01.01.2021· Compressive Strength of concrete = Maximum compressive load carried by specimen / Cross Sectional Area surface of specimen. Take it as, Cross sectional Area = 150mm X 1500mm = 22500 mm 2 or 225 cm 2. Assume the compression load is 400 KN, Compressive Strength = (400000 /22500) = 17.77 /9.81 = 181.22 kg/cm2 . Note – 1 kg is equal to 9.81 N . The same calculation is done for the

Compressive Strength of Concrete and Concrete

Compressive strength is the parameter that represents the concrete in the structural design. Mainly, there are two materials such as concrete and steel in the mix. Therefore, knowing the compressive strength is uttermost important for the designer. Factors affecting the Compressive strength of concrete

Compressive Strength Test Of Concrete Cubes -

Compressive strength as a concrete property depends on several factors related to the quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common]. For example, as per ASTM C39, a standard test method is given to get the compressive

Compressive Strength of Concrete | Definition,

29.01.2017· Concrete's compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000psi (28 MPa) and higher in commercial structures. Higher strengths up to and exceeding 10,000 psi (70 MPa) are specified for certain applications. Importance of Determining the Compressive Strength: Compressive strength results are primarily used to determine that the concrete
