The various factors affecting the mix design are: 1. Compressive strength It is one of the most important properties of concrete and influences many other describable properties of the hardened concrete. The mean compressive strength required at a specific age, usually 28 days, determines the nominal water-cement ratio of the mix. The other

What is Water Cement Ratio? Water Cement Ratio means the ratio between the weight of water to the weight of cement used in concrete mix. Normally water cement ratio falls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 …. M25) We all know that water cement ratio will directly affect the strength of concrete.
Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength, desired workability and durability as economically (value engineered) as possible.
Jan 24, 2013· By this definition the nominal maximum aggregate size for the material example above is also 1/2". However, if there were only 91% passing the 3/8" the nominal maximum aggregate size for that material would be 3/8", not 1/2".
