In this study, the mechanical properties of super flowing concrete containing fly ash were experimentally investigated and compared with those of ordinary concrete. Tests were carried out on five types of super flowing concrete mixes containing fly ash and three types of ordinary concrete mixes without fly ash. Flow test, O-funnel test, box test, L type test and slump test were carried out to obtain the properties for the workability of fresh concrete. The mechanical properties of hardened concrete were also investigated in terms of compressive strength, splitting tensile strength, modulus of elasticity, creep and drying shrinkage.
In fresh concrete, it was found that super flowing concrete had excellent workability and flow ability compared with ordinary concrete. Super flowing concrete also had good mechanical properties at both early and late ages with compressive strengths up to the 40 MPa at 28 days. The creep deformation of super flowing concrete investigated were relatively lower than that of ordinary concrete, but drying shrinkage was much higher.
