IS 516 (1959): Method of Tests for Strength of Concrete
www.iitk.ac.inconcrete work. Systematic testing of the raw materials, the fresh con crete and the hardened concrete is an inseparable part of any quality control programme for concrete which helps to achieve higher efficiency of the materials used and greater assurance of the performance of the concrete in regard to both strength and durability. The test ...

faculty-legacy.arch.tamu.edu= concrete compression strength a = height of stress block b = width of stress block f y = steel yield strength A s = area of steel reinforcement d = effective depth of section (depth to n.a. of reinforcement) With C=T, Asfy = 0.85 f´cba so a can be determined with f b A f a c s y c
AAA CE4135 ver2 - Memphis
www.ce.memphis.eduReinforced concrete is one of the principal building materials used in engineered structures because: • Low cost • Weathering and fire resistance • Good compressive strength • Formability all these criteria make concrete an attractive material for wide range of structural applications such as buildings, dams, reservoirs, tanks, etc. 1.3.
