Abstract:

The use of blended cement is becoming common in these days owing to the attempts made by the researchers in the direction of utilization of materials, which are available in natural abundantly. The new additives fly ash and polypropylene (Recron -3s) fibers, which is tried in recent times without any scientific study was found to be satisfactory. While, there is much to be done in order to standardize the properties of the said additives. The experimental study of this investigation consists of design of M40 grade concrete mix. The mix was worked out giving certain proportions by keeping the obtained water- cement ratio constant as 0.40. Concrete blends, viz. conventional concrete blends with differing rates of fly ash (0, 20, 30 and 40%) as cement replacement material were examined. Simultaneously the fibers were varied from 0 - 1% for each of the fly ash replacement in the concrete mix. The compressive strength and split tensile strength test were carried out at the ages of 7, 28 and 56 days. The impact of fibers and fly ash as cement replacement material on mechanical properties were analysed and compared with conventional cement concrete. This paper briefly shows the compressive strength of cubes and tensile strength of cylinders of all the concrete blends explored at 7, 28 and 56 days.
