Concrete Mix Design – early 1970s • Mix design by the Optimum Sand Method • Based on : British Compacting factor “ … proportions of fine and coarse aggregates which will give the maximum workability at any particular water-cement ratio and cement content. These proportions are also those requiring the least amount of water, which in turn yields the highest strength and durability ….. ” • MR Form 602 Procedure for Design of Concrete Mixes by Optimum Sand Method 1976 ASCP Forum 18 June 2018
