Proportion of M20 refers to the mix ratio of cement, sand, and aggregate in concrete.
M20 concrete mix ratio is 1:1.5:3 (cement:sand:aggregate)
This means for every 1 part of cement, you need 1.5 parts of sand and 3 parts of aggregate
Proper proportioning is crucial for achieving desired strength and durability of concrete
Mix design is the process of selecting suitable ingredients and determining their proportions to produce concrete with desired properties.
Involves selecting the right combination of materials like cement, aggregates, water, and admixtures
Proportions are determined based on desired strength, workability, durability, and other properties
Testing is done to ensure the mix meets specifications and performance requirements
IS Codes of cement are standards set by the Bureau of Indian Standards for quality control and testing of cement products.
IS 269: Specification for Ordinary Portland Cement
IS 455: Specification for Portland Slag Cement
