ASTM A36 steel is one of the most widely used carbon structural steels, although the carbon content of A36 material is maximum 0.29%, it is considered to be the mild steel (content of carbon 0.25%).. A36 mild steel is often compared to AISI 1018, A36 carbon steel is commonly hot rolled, while 1018 steel is commonly cold rolled.. Notes:There are two versions that define low Characteristic Strength Of concrete - Engineering DiscoveriesEach concrete grade e.g. C30/37 is characterized by two equivalent strengths, which in this specific example are 30 MPa and 37 MPa. The first is the characteristic strength f ck of a standard concrete cylinder and the latter is the characteristic strength of a standard concrete cube.
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 in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

C 35 means it is the compressive strength of concrete is 35 MPa (N/mm2). The compressive strength of concre is tested by casting 15x15x15 cm concrete cube and curing it for 28 days and then crushing it in machine to get the compressive strength of the concrete. 6.1K views.

C45 concrete Usually specified at design stage, this form of ready mix concrete is designed to comply with a compressive strength denoted by the class of mix. Mixes are measured in grades, with strengths ranging from 10 Newtons through to high strength concrete mixes available online at 45 Newtons.
