Grade of concrete refers to the strength of the concrete mix design, typically denoted by a number such as M20 or C30.
Grade of concrete is determined by the ratio of cement, sand, and aggregates in the mix.
Higher grade numbers indicate higher strength concrete.
Common grades include M20, M25, M30, etc. for mix design method and C15, C20, C25, etc. for nominal mix method.
Compressive strength of concrete is the ability of concrete to withstand loads that tend to compress it.
Compressive strength is measured by testing concrete cubes or cylinders in a laboratory.
It is important for determining the quality and durability of concrete structures.
The strength of concrete can vary depending on factors like mix design, curing conditions, and age.
Typical values for compressive strength range fro...
Curing is the process of maintaining adequate moisture and temperature for concrete to ensure proper hydration and strength development.
Curing can be done by methods such as ponding, wet covering, steam curing, and using curing compounds.
Ponding involves creating a pond of water on the concrete surface to keep it moist.
Wet covering is done by covering the concrete with wet burlap, sand, or other materials to retain moi...

Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
Water cement ratio is a crucial factor in determining the strength and durability of concrete.
A lower water cement ratio results in stronger and more durable concrete.
The ideal water cement ratio varies depending on the type of concrete mix and its intended use.
For example, a typical water cement ratio for general purp
