What is compressive strength of M15 in 7 days as per IS?
3/4 of its strength
What is M15 grade?
Ans: M15 grade indicates the grade of concrete used in the structure i.e M indicates the design mix proporation and 15 indicates the compressive strength of conctrete at 28 days in N/mm2
What is the compressive strength of M10 concrete at 7 days?
For M25 grade concrete the seven days crushing for site condition shall be not less than 67 % of M25, i.e not less than 16.75 N/mm2 But for target strength of M25 for mix design taken i.e for M25 it is 32 and the 7 days strength shall not be less than 22 N/mm2
What is the grade of concrete?
The grade of concrete refers to its compressive strength measured in megapascals (MPa) or pounds per square inch (psi) after 28 days of curing. Common grades include M15, M20, M25, and so on, where the number indicates the characteristic strength of the concrete mix. Higher-grade concrete has a greater strength, making it suitable for structural applications requiring durability and load-bearing capacity. The selection of the appropriate grade depends on the specific requirements of the construction project.
What is c35 grade concrete in psi?
It is the bearing capacity in N/mm2 when tested on 21 day on a hydraulic testing m/c When we tested this grade concrete cubes on 28th day the compressive strength value have to come 35 N/mm2.
