This exclusive construction article focuses on the different types of factors which influence the properties of concrete.

Properties of concrete mainly depend on the blending ratio of cement, sand, aggregates and water. The proportions of these materials, manage the following different concrete properties:

• Grades (M20, M25, M30 etc.) • Compressive strength • Characteristic Strength • Tensile strength • Durability • Creep • Shrinkage • Unit weight • Modular Ratio • Poisson’s ratio                            

Grades of concrete: Concrete is recognized with its grade that is specified as M15, M20 etc. Here M signifies concrete mix and number 15, 20 indicates the stated compressive strength (fck) of 150mm cube at 28 days, provided by N/mm2. So, concrete is recognized with its compressive strength. M20 and M25 are considered as the general grades of concrete. The higher grades of concrete are applied for severe, very severe and extreme environments.
