1- Compression Test On Concrete Cores. Extracting concrete samples (Read More: Challenges of Concrete Coring) and testing for compressive strength is often considered the most cost-effective and most reliable solution. In fact, many codes and guidelines consider this the only approved method for evaluating concrete strength.

Non destructive testing of concrete is a method to assess the properties and strength of concrete in existing structures without causing damage. These tests for concrete are employed to assess compressive strength and other properties of existing structures, providing immediate results and revealing the actual strength and properties …

The concrete slump test is known as "Standard Test Method for Slump of Hydraulic-Cement Concrete" and carries the code (ASTM C 143) or (AASHTO T 119). United Kingdom & Europe In the United Kingdom, the Standards specify a slump cone height of 300-mm, a bottom diameter of 200-mm and a top diameter of 100-mm.

A simple way to confirm the occurrence of ASR in concrete is by using luminescent methods [181], [182], [183]. These methods make use of the cationic exchange affinities of the products generated by the ASR which are essentially constituted by hydrated silicate of alkali and calcium [21], [181], [184], [185].
