Concrete compressive strength is the most common test conducted for acceptance of concrete. Test cylinders are prepared for standard curing in accordance with ASTM C 31 and tested in accordance with ASTM C 39. The ACI 318 Building Code establishes statistically based acceptance criteria for cylinder tests and criteria for strength tests on
When the mix is ready, the tests on mix are proceeding. Tests on Trial Mix Design. The slump tests are conducted to determine the workability of fresh concrete. Concrete is placed and compacted in three layers by a tamping rod with 25 times, in a firmly held slump cone. Concrete Mixed Design Method (BS Method)
Here are the IS codes which cater to the need of civil engineering relating to Cement and Concrete. These IS codes include the Standardization in the field of all types of cement, pozzolana, testing sand, concrete, aggregates, instruments for cement and concrete testing, cement plant machinery and ferrocement concrete, reinforced concrete and pre stressed concrete, test methods for concrete

The slump test is a means of assessing the consistency of fresh concrete. It is used, indirectly, as a means of checking that the correct amount of water has been added to the mix. The test is carried out in accordance with BS EN 12350 2, Testing fresh concrete. Slump test.
Cement Standards and Concrete Standards ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and
