Abstract :

High Volume Fly Ash concrete system addresses all the major sustainability issues. It is recommended over the ordinary concrete as it considerably saves cement and also prevents environmental pollution. The use of fibres improves specific material properties of the concrete, impact resistance, flexural strength, toughness, fatigue resistance, and ductility. In this paper an attempt is made to study the mechanical properties of High Volume Fly-Ash Concrete with addition of fibres at 0.1, 0.2, and 0.3% of cement and with 60% fly ash replacement with cement. It is found that fibre additions have increased its strength characteristics considerably over the ordinary cement concrete. A mathematical model was developed using SPSS 20 for the strength parameters of HVFAC with fibres. The major parameter that affected strength was total binders and water-binder ratio.
