The nominal mix for M25 grade is (1:1:2). The quality of concrete depends on a number of factors and the standard mix just gives us a rough estimate of the quantities of material required, this is exactly where a design mix procedure is required as it is evident from the results that for the same mix
From Mix Slum test, the concrete is workable and had a true slump of about 25 mm and it is free from segregation and bleeding. required slump = 50-75 mm . So modifications and changes are needed in trial mix 1 to get the desired workability.
