Dear,

IS456 specify the minimum cement content for the structural concrete as 300kg.You can acheive upto 25N/mm2 with same cement content changing the water-cement ratio. About nominal concrete like 1:2:4 for 28days you can get 22 to 26N/sqmm. As per IS456 the minimum requirement for structural concrete is M20.

Based on the trails with water-cement ratio you can confirm the grade as M20. And 65 to 75% will be the 7days strength.

 Dear friends,I just need clarification abt the grade for mix 1:2:4(someone telling it as M20 but someone telling it as M15). i know its a nominal mix but while testing for a compressive strength there was a confusion abt the 28 days strength. Also tell me how much % of strength should be obtained for 7 days strength. Is there any codes available to find out Grades for nominal mix concrete. With thanks & regards,Dhamodharan KAsst.

Hi,

The difference between OPC 33, 43 & 53 is for the minimum required Characteristic compressive strength at 28 days of curing ie 33 Mpa,43Mpa & 53Mpa.

PPC is Portland Pozolana Cement containing pozolana such as Fly ash GGBS etc.

Slag cement is cement containing slag.
