By a chemical reaction.
The tensile strength of concrete is 10% of it's compressive strength.
Yes, the characterisrtic strength of a concrete is the same as the compressive strength
the moisture of concrete is main strength for reinforced concrete structure
tensile strength is approximately between .08 to .15 of compression strength in concrete
Concrete with compressive strength more than 55 MPa is known as high strength concrete.It is used in the construction of bridges, dams. etc.,High strength concrete is produced by adding normal constituents of concrete with admixtures.
It removes air pockets naturally created in a poor which keeps out moister and improves the strength.
how does the fineness modulus of aggregate affect the strength of concrete
how does the fineness modulus of aggregate affect the strength of concrete
The equivalent concrete for M-30 cylinder strength is M-40 cube strength
Cylindrical strength = 85% of Cube strength.
There is no set ratio for a concrete requiring a compressive strength of m50. It is usually created according to the factors of the site condition and location.
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
