Technical Questions

ACI Committees, Membership, and Staff have answered common questions on a variety of concrete related topics.

Evaluating the properties of hardened concrete

Q. What types of tests are performed to evaluate the properties of the hardened concrete for its suitability for a given purpose?


A. Specimens for strength tests in compression (or in flexure, if required) should be made from all trial batches and from several batches after a satisfactory mixture has been established to determine if the strengths are within the range intended. Also, if concrete is exposed to the environment and resistance to degradation is of concern, tests for chloride penetration, shrinkage, resistance to freezing and thawing, and others would be desirable.
