AS 1012.1:2014 Methods of testing concrete - Sampling of concrete (FOREIGN STANDARD) This Standard sets out the method for obtaining samples of freshly-mixed concrete - (a) directly from mixers; (b) from agitator or non-agitator units; (c) from concrete deposited in readiness for casting; and (d) from concrete

The most rapid and economical of the methods investigated (and the one requiring the least skillful operation) was found to be the Schmidt rebound hammer. This device, which has been available for a number of years and has been widely used in concrete testing


Guide to Evaluation of Strength Test Results of Concrete

Conclusions regarding concrete compressive strength can be derived from a series of tests. The characteristics of concrete strength can be accurately estimated when an adequate number of tests are conducted in accordance with standard practices and test methods. Statistical procedures provide valuable tools when evaluating strength test

Concrete Testing. BCRC's consultants have been involved in the use and development of Non Destructive Testing (NDT) for over 30 years. Frank Papworth commenced his involvement with NDT in 1978 when he managed one of the UK government sponsored programmes in 'Concrete

6 Ways You Know to Test Concrete Strength and 1 You May

1.1 These test methods provide various testing procedures commonly used for evaluating characteristics of concrete masonry units and related concrete units. Methods are provided for sampling, measurement of dimensions, compressive strength, absorption, unit weight (density), moisture content, flexural load, and ballast weight.
