What is ultimate 28 day concrete strength?
The strength of concrete on the 28th day is considered full strength with regard to the engineering calculations for its use. Concrete continues to get hard for 100 years or more, as long as it has water on it now and then. For a 6-sack concrete mix, its 28 day compressive strength should be at 4,000 psi or greater.
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.
What is the compressive strength of M35 concrete at 14 days?
35N/mm2 the above answer is terrible. at 14 days there is no guarantee of what the strength will be, as strength gain is rapid with pue OP it will tend t be greater than 50% of the target characteristic strength; however, with any pozzolans in the mix (e.g. PFA/GGBA) the strength gain over time is slower and can be espected to achieve greater strengths than that of pure OPC the question is too vague to answer. the mix design is pivotal in calculating strength
What is the compressive strength of cement mortar?
Compressive strength measures the largest compression force the material can withstand before it loses its shape or fails.
What is the minimum characteristic strength for 7 day concrete cube?
67%
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 C25 concrete?
C25 concrete is a concrete having compressive strength of 25MPa when tested at the 28th day after casting. The specimen can be cube(150x150x150) or cylindrical(125mm by 250mm high). The cube strength has 0.8 times that of cylindrical specimen due to shape factor.
What is the strength of M-30 after 7 days?
Seven days strength of any concrete usually comes 67% of 28 day strength. So 7 day strength of M30 may be .67*30=20.10 MPa
What is strenGth of M-30 after 30 days?
Seven days strength of any concrete usually comes 67% of 28 day strength. So 7 day strength of M30 may be .67*30=20.10 MPa
