tests to be done on concrete The slump test: the slump test shows the workability of concrete. The compression test: the compression test shows the best possible strength Concrete can reach in perfect conditions. Testing should always be done carefully. Wrong test results can be costly. SAMPLING The first step is to take a test sample from the large batch of concrete. This should be done as soon as discharge of the concrete commences. The sample should be representative of the concrete supplied. The sample
