Diffeece between nominal mix and design mix?
a nominal mix is that mix in which we adopt the various ingredients such as1:2:3,1:2.5:4etc here the strength will not be the desired strength and generally here we take the ingredients per unit vol a design mix is that mix in we find the ratio of the different ingredients as per the desired strength and the ingredients would be in per unit weight
What is the difference between leAn concrete and ready mix concrete?
Lean mix concrete is used for substructures like foundations,piles,etc.,Ready mix concrete is used for superstructures and also for mass construction.Generally, quality of ready mix concrete is good when compared to the lean mix concrete.Workability of lean mix concrete is high when compared to RMC.
What is the mix ratio for blinding or mix concrete?
1:2
What is M20 concrete grade?
M20 refers to the grade of the concrete generally used in construction purpose. Here, M refers to mix & number 20 refers to the characteristic strength of concrete. the proportions of this grade is (1:1 1/2: 3). Along with this there are some more grades used in constructions i.e., M5, M7.5, M10, M15, M25, M30................. M80
What is C30 grade of concrete?
The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance (withstanding a compression) of 30 N/mm2 per square millimetre in 28 days.
How much cube strength required for m20 concrete mix?
does not exceed 30N/mm2

What part of the body is tougher than concrete?
the bones in the thigh, I'm not sure if they are tougherthan concrete but they are as tough as concrete. (:I guess it depends on what concrete you use (and if you mix it with agregate in the right proportions), the bones are probably as tough as some concretes.Tooth enamel is the hardest part of the body and probably the contender for the toughest.

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.
