1.Plain concrete is formed from hardened mixtures of fine aggregates, coarse aggregates such as crushed stones or gravels, air, and other admixtures often used. 2.In China, the hot-rolled steel bars are classified as HRB335, HRBF335, HRB400, HRBF400, AND HRBF500 according to their strengths. 3.usually, the size of the steel bars used in concrete structure range from to at an interval of 2mm, in order to distinguish steel bars from each other easily 4.Take a mild steel bar with an initial cross-section area of As and subject it to a tension of T, then the stress o; can be defined as 5.It is more difficult to measure the tensile strength than the compressive strength because of the problems of testing machines. A number of methods are available for tensile test. In China, the most commonly used methods
