Determination of appropriate mix ratios for concrete grades . Kazeem ADEWOLE, Wasiu O. AJAGBE, Idris A. ARASI 82 Industrial Standards for cement, NIS 444-1:2003[14]. From 2003 till date, Portland-limestone cement is the only bagged cement in the Nigerian open market. Concrete grades or strength classes are specified in terms of the minimum 150 mm
As per IS 456 the max qty of cement allowed is 400 kg per cum for all normal strength concretes upto My60 keeping shrinkage cracks etc. M25 concrete is never equal to 1:1:2 of nominal mix. It is uneconomical and may not yield 25 n per sq mm as attained by M25, 28 days characteristic compressive strength.
of ingredients of a concrete mix is in the terms of parts or ratios of cement, fine and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate. The proportions are
