How do check the mixdesign for concrete is correct or not?

for checking the mix design for concrete, we need to initially prepare the mix n take samples n do cube tests to find the compressive strength n find out if desired strength is obtained for 7 days & 28 days strength. if desired strength is not obtained v need to adjust the mix proportions. its actually a trial n error method.


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 .


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 the compressive strength of M10 concrete at 7 days?

The compressive strength of M20 concrete at 28 days typically falls in the range of 20 to 25 megapascals (MPa), which is equivalent to 2900 to 3600 pounds per square inch (psi). M20 is a mix designation for concrete, where "M" stands for "mix" and the number 20 represents the characteristic compressive strength of the concrete mix in MPa. Please note that the actual compressive strength of M20 concrete can vary depending on several factors, including the quality of materials used, the water-cement ratio, the curing conditions, and the testing procedures. To ensure the desired strength, it's essential to follow the recommended mix proportions and proper construction practices during the preparation, placing, and curing of the concrete. Additionally, testing of concrete samples is typically conducted in a laboratory environment to determine the 28-day compressive strength accurately.


What is compressive strength of M15 in 7 days as per IS?

3/4 of its strength


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


How many weeks are in 525 days?

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.


Why 7 days compressive strength is concider?

concrete strenght gain at first 7 days much increase so we consider 7days strenght
