Why M30 concrete is used in foundation?
M30 concrete is commonly used in foundations due to its high compressive strength of 30 MPa, which provides adequate support for various structures. Its balanced mix of cement, aggregates, and water ensures durability and resistance to environmental factors. Additionally, M30 concrete offers good workability, making it easier to place and finish in foundation applications. This strength and reliability make it suitable for both residential and commercial construction projects.
What are the cube result achived in 7days M30 Concrete?
around 22.. the basic rule is around 70% of target mean strength..
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
Which purpose you are using M30 grade concrete?
we use M30 grade concrete commercial slabs like shopping malls . college buildings
Why is the 28-days compressive strength of concrete generally specified?
It is attributed to two reasons: 1. Strength of concrete grows faster in initial days and this process of gaining strength slow down with time. This can be said as stabilization in value of gained strength of concrete. After approximately 20 or some more days, strength value get stabilize and does not change too much with time. Therefore, compressive strength is taken after approximatley 3 weeks time. 2. These tests have to performed practically and date record is needed to be maintained. Therefore, if test duration is a multiple of 7 (7 weekdays) then it is more easy to remind. It is the reason we have 28=7x4 days to note down compressive strength of concrete. for ex: if we start test on monday then we know that after 4 weeks on same time on monday we can finish the compressive strength test.
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
What does the mean of M30 payment terms?
Payable in 30 days
Seven day compressive strength of M25?
The compressive strength of 7 days shall be about 70% of the 28-days compressive strength. If your compressive strength at 28-days is 25 MPa, then the 7-days compressive strength expected to be (0.70X25MPa)=17.5 MPa Regards, Sami
What is compressive strength of M15 in 7 days as per IS?
3/4 of its strength

What should be the compressive strength of mortar cubes in 3 days and 7 days?
The compressive strength of mortar cubes typically reaches about 50% of its expected strength at 3 days and approximately 70% at 7 days. For standard mortar mixes, this often translates to a compressive strength of around 7 to 10 MPa (megapascals) at 3 days and 10 to 15 MPa at 7 days, depending on the mix design and curing conditions. However, specific values can vary based on the materials used and environmental factors. Always refer to relevant standards for precise requirements.
How many days concrete has to be cured prior to steel erection What counts days or strength achieved by concrete?
the strength that it has gained is the main thing, but usually 5 to 7 days as a rough guide.
What is the strength of concrete after 28 days?
The compressive strength of M25 concrete at 7 days will be between 6-7.5 N/mm2 .
What is 7 days strength for M 7.5 mix?
It is about 13.5 N/mm2
Why 7 days compressive strength is concider?
concrete strenght gain at first 7 days much increase so we consider 7days strenght
