Concrete Mix Design Test

top 6 important quality tests of concrete,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..compressive strength of m20 concrete -cube test procedure,m20 concrete cube test procedure. a) measure the dry proportion of ingredients (cement, sand & coarse aggregate) in ratio 1:1.5:3 as per the m20 concrete. the ingredients should be sufficient enough to cast test cubes..
