Compressive strength of concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

24.08.2021· Compressive strength of Concrete Formula: The Compressive strength of specimen can be calculated by dividing maximum load carried by the specimen by cross-sectional area of the specimen cubes. The surface area of specimen: = 150 x 150 = 22500mm² = 225cm² Assume, The Max compression load is 450KN.

07.07.2016· It is obtained by testing concrete cylinder specimen. However, empirical formulas can be used to convert cube strength to cylinder strength and vice-versa. As per Indian code definition “ The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck).

What is the formula of compressive strength of a 7-day concrete cube in M20? Unfortunately that “formula” contains a number of variables to which I am not privy. Variables such as what binders are in the mix, and the temperature and moisture condi...

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

Compressive Strength of concrete = Maximum compressive load / Cross Sectional Area. Cross sectional Area = 150mm X 150mm = 22500 mm2 or 225 cm2. Assume the compression load is 450 KN, Compressive Strength = (450000 N / 225)/9.81 = 204 kg/cm2. Note – 1 kg is equal to 9.81 N.
