## Concrete Grade Used in Construction Quality Assurance

Concrete Grade C40/20 and C45/20: These concrete grades are used for structural members and systems that are directly or indirectly experiencing loads in itself such as slabs, foundations, columns, and footings. Basically, these are middle to high graded concrete with a certain design capacity as these grades have direct impact on the

## Conventional grade C20, C25 and C30 concrete mix ratio

The concrete mix ratio refers to the proportion of the components in the concrete. The concrete mix ratio is usually represented by the quality of various materials per cubic meter of concrete, or amount proportion of various materials. The basic requirements for the design of concrete mix ratio are: 1, meet the strength grade of concrete design.

## Mix Design for Pumped Concrete with PPC, OPC, OPC+Flyash

For OPC + Flyash Mix fine aggregate is about 43%, 10 mm 20% and 20 mm is 37%. This is also within the permissible limits of recommended grading for pumped concrete.

## What is the difference between C30 concrete and M30

Mar 12, 2016 · What is the difference between C30 concrete and M30 concrete? Is the difference merely that C30 uses cylindrical samples, where as M30 uses cubic samples for compressive test? Is there any difference in mix designs of both?

## Mix ratio of C40 concrete DIYnot Forums

Apr 02, 2014 · The reason you can't find a prescribed mix ratio for C40 is it doesn't exist. BS5328 only goes up to 25N and anything above 20N can't be mixed with all in ballast. That's not to say you couldn't end up with a mix higher than 25N just that it's not predictable based on the mix ratio. The only way to guarantee 40N is readymix.
