Slump test on fresh concrete
Webb2 apr. 2024 · The slump test is the most commonly used method of measuring the consistency of concrete which can be employed either in a laboratory or at the site of work. It is not a suitable method for very wet or very dry concrete. It does not measure all factors contributing to workability, nor is it always representative of the placability of the concrete. WebbA concrete slump test is one of the ways to check the quality and suitability of a mix, by ensuring the water to cement ratio is correct. Performing a concrete slump test will also provide the opportunity to …
