Strength development in concrete Understanding Cement

The SI unit for concrete strength measurement is the Mega Pascal, although 'Newtons per square millimetre' is still widely used as the numbers are more convenient. Thus 'Fifty Newton concrete,' means concrete which has achieved 50 Newtons per square millimetre, or 50 Mega Pascals.

214.4R-03 Guide for Obtaining Cores and Interpreting

Compressive Strength Results ACI 214.4R-03 Core testing is the most direct method to determine the compressive strength of concrete in a structure. Generally, cores are obtained either to assess whether suspect concrete in a new structure complies with strength-based acceptance criteria or to evaluate the structural capac ity of

PREDICTING CURRENT COMPRESSIVE STRENGTH

compressive strength of concrete is a very important property. Even when concrete is used in applications where other stresses are of primary importance, the compressive test is used because it is the easiest property to measure. The results of this test are generally used as a measure for the quality of concrete. Concrete compressive strength
