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.

  • Mix ratio for M35 concrete is 1:1.6:2.907.
  • compressive strength is 35N/mm2 @ 28 days.
  • 1 part of cement, 1.6parts of sand, 2.907 parts of coarse aggregate.

What is the difference between concrete grade C35 and C35A?

The main difference between concrete grade C35 and C35A lies in their composition. C35 concrete is a standard concrete mix with a minimum strength of 35 megapascals (MPa), while C35A concrete is a special mix that includes air-entraining agents to improve workability and durability. The inclusion of air-entraining agents in C35A helps to increase the concrete's resistance to freeze-thaw cycles and reduce the risk of cracking. Overall, C35A is more suitable for applications where improved durability and workability are required.

What does mean concrete 3000 psi?

Concrete 3000 psi means that the concrete has a compressive strength of 3000 pounds per square inch (psi). This measurement indicates how much pressure the concrete can withstand before cracking or breaking. A higher psi value generally means stronger and more durable concrete.

How much PSI takes to brake concrete?

Generally speaking, concrete is rated anywhere from 2000 psi to 10,000 psi. Of course if you do NOT use the proper ratio of aggregate (usually sand) to cement and water you can make concrete that is even weaker. When concrete is ordered from a delivery company, you specify the strength of he mix or pour that you want.
