Types and properties of steel

Steel is an alloy of iron. It is formed by heating iron and combining carbon (0.1-1.7%) with it and minor amounts of other elements such sulfur, chromium, manganese, nickel, etc. Thousands of steel grades have been published, registered, or regulated around the world, each with its chemical composition, and special numbering systems have been devised in various countries to classify the vast number of alloys.

Concrete is required for walls of a building that will be Mild Exposed to freezing and thawing. The cross section of a wall is 300 x 1500 mm. The smallest spacing between reinforcing steel is 50 mm. The specified compressive strength of Compressive strength of concrete at 28 days is 35 MPa and a slump of 55 mm. Portland cement type I is used with specific gravity of 3.12, maximum size of aggregate 27 mm and fineness modulus of fine aggregate is 2.4, absorption capacity and moisture content of fine aggregate are of 0.92%, and 1.95% respectively. The dry-rodded unit weight of coarse aggregate is 1820 kg/m³, absorption capacity and moisture content of coarse aggregate are of 0.75%, and 1.85% respectively. Both aggregates have a bulk specific gravity (SSD) of (2.45). The aggregates conform to the ASTM C33-84 requirements for grading.
