British Method of Mix Proportioning
Current method of mix design of concrete is that revised by Dept. of environment (UK) in 1988. British Method recognizes the durability requirements of mix selection. The design is applicable to normal weight concrete made with Portland Cement only or Blast furnace slag/fly ash. Refer the ppt attached for step by step process in the mix design.
Step 1 – Determination of free w/c ratio in relation to compressive strength
Step 2 – Determination of water content
Step 3 – Determination of Cement content
Step 4– Determination of Total Aggregate content
Step 5 – Fine and Coarse Aggregate Content
Limitations of British Method
This method is based on the characteristics of the materials available in UK.
Hence it may not be applicable to other parts of the world
