Which grade of concrete is used for bridge construction?
53 grade of concrete is used for bridge construction which is a high strength grade of concrete. The compressive strength of 53 grade is high which is 53N/mm2.
Which grade of concrete is used for column?
Standard concrete and concrete of grade M20 is applicable for Reinforced Cement Concrete (RCC) works for slabs, beams, columns and so on.
Can concrete be adapted for bespoke designs?
When I work with a client we set out to create a completely bespoke design for the home, garden or business. I have seen how the durability and versatility of concrete can radically transform the design of any project. This technology allows unlimited use of this material in interior and exterior design.
Why tensile strength of concrete is low?
The outer surface of the large solid aggregates or the ITZ is normally filled with calcium hydroxide which is a bi-product of concrete’s hydration reaction. This calcium hydroxide layer is weak and porous, contributing to a weak tensile strength of the overall structure.
What is design mix concrete?
Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures. So, concrete mix design can be stated as Concrete Mix = Cement:Sand:Aggregates.

What is minimum grade of concrete?
M20 is the minimum grade requirement of concrete for reinforced cement concrete work with mix ratio 1: 1.5: 3, means 1 part of cement, 1.5 parts of fine aggregate and 3 parts of coarse aggregate.
What is concrete versatility?
Versatility. Whatever the application, concrete has proven its value and flexibility time after time. Its incredible versatility makes it useful for an array of uses, including: roads, buildings, driveways, highways, pathways, garages, patios, and much more.
What is used in precast concrete structure?
Precast concrete is a construction product produced by casting concrete in a reusable mold or “form” which is then cured in a controlled environment, transported to the construction site and lifted into place (“tilt up”). More recently expanded polystyrene is being used as the cores to precast wall panels.
What is the grade of concrete?
