Chapter 4 Construction Details - Caltrans design will require a new mix design submittal. An integral part of quality assurance is the review of the submitted concrete mix designs for compliance with contract requirements. Attention must be paid to concrete requirements within the plans and specifications because, on most projects, there will be a need for multiple concrete mix Top 6 Important Quality Tests Of Concrete | Quality ... After batching the concrete, a sample of fresh concrete shall be taken to test for slump tests and the samples for compressive strength test be taken too. This is to make sure that the batched concrete is complying with the mix design before it's released from the batching plant. Concrete Testing Lab in India | Sigmatest Lab Design mix: This test helps in determining the suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and work ability as economical as possible, is termed as concrete mix design.
