Concrete Header Block Dimensionsdifferent Types Of Concrete Grades

types of concrete & characteristics | concrete classification,types of concrete. some common and main types of concrete are: normal concrete. high strength concrete. high performance concrete. air entrained concrete. light weight concrete. self compacting concrete. shotcrete. pervious concrete. roller compa cted concrete. explanation of different types of concrete are as below: normal concrete.calculate cement sand & aggregate - m20, m15, m10, m5,understanding concrete grades . based on strength, concrete is classified into different grades like m5, m7.5, m10, m15, m20 etc. in concrete grades, the letter “m” stands for “mix” and the following number stands for characteristic compressive strength of concrete in 28 days in the direct compression test..
