Nov 01, 2018· 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. Concrete mix ratios are expressed in two ways: one is expressed in materials used per cubic meter of concrete (Water: Cement: Sand: Gravel), and the other is expressed as a ratio of various materials. for example, C:S:G

Get QuoteWhat are the grades of concrete. As we know that concrete are made of mixing of cement sand and aggregate in required proportion. What are the grades of concrete, according to BS (British standard), the grades of concrete represented as C10, C15 & C20 is known as normal grade of concrete, C25, C30, C35, C40 & C45 is known as standard grade of concrete and C50, C55, C60, C65, & C70 is
Get QuoteConcrete grades include; C7/8 Concrete, C10 Concrete, C15 Concrete, C20 Concrete, C25 Concrete, C30 Concrete, C35 Concrete and C40 Concrete. Different construction projects will require concrete of certain strength ratings, so understanding the difference between concrete grades is key to finding the ideal mix for your specific requirements.

Get QuoteOne of the most common lightweight mixes we deal with is GEN 3 / C20 concrete. With a strength rating of 20 newtons after 28 days, this mix is commonly used for domestic projects, but can also be used for certain commercial applications. As a lightweight mix, GEN 3 / C20 concrete has the highest cement content of all other individual GEN mixes.
