000004655 520__ $$2eng$$aHigh performance concrete (HPC) has recently become a widely used concrete construction material for modern buildings, bridges, and pavements, etc. To produce such a better quality of concrete, chemical and mineral admixtures such as fly ash, slag cement, and silica fume, as well as air-entraining agents are commonly used in the field construction. It has been found that high performance fly ash concrete can improve the workability, ultimate strength and durability of the concrete. However the enhancement of ductility in concrete, and concrete structures as a whole is still inconclusive and needs more research. This paper presents a complete stress-strain behavior and its empirical equation of high performance fly ash concrete under compression. The proposed empirical equation also studies the effects of steel fibers and/or steel hoops in fly ash concrete, and can be found useful in designing modern fly ash concrete structures.
