There are plenty of different purposes people have for concrete; it can be used for foundations, flooring, walls and more.But not every concrete mix is the same, and depending on what you are aiming to achieve, you need to get a concrete mix that is fit for purpose.

Table 1 lists the mix proportion of C50, C40, C30, C25, and C20 ordinary-air-entrained concrete by weight. Effect of fast freeze-thaw cycles on mechanical properties of ...
As per BS 8500-2 British/European standards The grade of concrete is denoted as C10, C15, C20, C25, etc., 'C' which means 'Concrete Strength class' and number behind C refers to characteristic Compressive strength of Concrete in N/mm2 @ 28 days when tested with the 15 cm dia. & 30 cm height cylinder in a direct compression test.
The grade of concrete is determined by its compressive strength at 28 days after pouring, measured in psi. The higher the psi rating of a given concrete mixture, the greater its strength. Most residential applications require at least 2,500 psi, according to the National Ready Mixed Concrete Association, while commercial work requires 4,000 psi ...

Basic properties. The following Table gives the compressive strengths (based on cylinders and cubes), modulus of elasticity and tensile strength for various strength classes of normal weight concrete. They are taken from Table 3.1 of the Eurocode 2, which gives additional properties as well as values for other strength classes.
To enable the concrete producer to design and produce a suitable concrete, certain information must be provided in addition to the specification, e.g. where the concrete needs to be pumped or a high quality finish is required. References. 1 BRITISH STANDARDS INSTITUTION. BS 8500: Concrete - Complementary British Standard to BS EN 206-1. BS1, 2006.
The most common form of designed concrete is that defined by the characteristic compressive strength at 28 days and identified by the strength class. For example, class M30 (C25/30 as per British Standards) is the concrete having a characteristic compressive cube strength of 30 N/mm 2.
Concrete Grade C60/20: This concrete grade is used for the most important part of the structural concrete element which is "Column" and "Shear wall." The highest quality concrete grade is the high strength concrete grade. This is the grade used for beams and girders, columns and other major structural members.
GRADE: C25 CONCRETE. Strength: 25 Newtons after 28 days. A multi-purpose concrete that is used on a wide range of commercial and domestic construction sites. C25 is often used when pouring foundations (footings). It is also the ideal concrete for domestic …

Meet the above conditions to save cement and reduce concrete costs. Concrete is divided into several strength grades according to strength, and the strength grade of concrete is strongly divided by compression. The strength of concrete is divided into twelve grades such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55 and C60.
Jan 04, 2013· So we can say the given concrete mix has a characteristic strength of 30 MPa or it is a M30 grade mix. M- Mix * Note: For a 95% confidence level k=1.64, hence k value varies on the confidence level of the experiment. Definition:

It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength […]
M signifies that a CUBE of sizecm*cm*cm made of cement+ coarse aggregates+ Fine aggregates in such a ratio that its characteristic strength isN/mm^2 after days of curing,whereas C symbolizes a CYLINDRICAL sample in which cement+ fine aggregates + coarse aggregates are mixed in such a ratio that its characteristic strength after days of curing is N/mm^2.Usually Strength of Cylinder sample= •8 ...
