Mix design concrete procedure has two objectives. One to achieve the minimum required strength and two to prepare the concrete in the most economical manner. Cost-wise, all concrete depends primarily on two factors, namely the cost of labor and the cost of material. Labor cost includes form-work, batching, mixing, trans porting, and curing, with slight variations between good bad quality concrete.
The mix proportioning of M40 grade high durability concrete resulted in a triple cementitious blend mix with a binder Content of 508 kg/m3 with water-binder ratio of 0.29. This mix could achieve average RCPT value of 551 coulombs. The water permeability was reported 12.5mm against a stringent maximum specified value of 15mm.

Ordinary concrete includes grades of M10, M15 and M20. The standard ones include M25, M30, M35, M40, M45, M50, and M55. The high strength concrete includes M60 and M80 grades. Generally M10 and M15 grades of concrete are used for leveling course, and bedding for footings.
From the IS Code standard, Assuming the water-cement ratio for M20 is 0.5; The reason for that 1.55 has been already discussed in the concrete ingredients calculation topic. So the required Cement Volume – 0.3875 m3 or 11.16 Bags Sand Volume – 0.3875 m3; Coarse Aggregate – 0.775 m3; Required Water – 193.75 Litres

For example, for an M20 concrete mix, one can assume w/c as 0.5 or 0.55 to start with and accordingly cement content will vary. The scope of this study is to compare BIS and ACI recommended mix design guidelines. The calculation processes in the two codes are summarised by illustrating the design steps. A typical M20 mix design
Sep 04, 2017· Added to that we carried outs trial mixes at various water cement ratios(0.32-0.26) which helped us in understanding the behavior of concreter at lower water cement ratio which was displayed in graphs in previous slides.
