Experimental Investigation On Study Effect of Polyester Fibre on Abrasion and Impact Resistance of High Volume Fly Ash Concrete with class-F Fly Ash

Use of supplementary cementing material is one of the emerging area and need in the field of cement concrete construction and technology to address the issue of sustainability. This will take care of economical and environment factors to gather with concrete life cycle analysis. Fly as is one of the major by product of coal fired thermal power generation plant. Production of fly ash in Indian context is of order 132 million tone annually; against which the utilization is of order 42% in all possible area of application. High Volume Fly Ash (HVFA) concrete is one of the important area for large scale utilization of pulverized coal ash as concrete is most widely use material on earth after water. Use of fly ash in concrete will address the all issues of sustainability by less utilization of cement the principal binder a major source of green house gas contribution, durability aspect due to its pozzolanic property and less consumption of virgin material. Though use of High Volume Fly Ash (HVFA) concrete is proven technology since last two decade the use is till date is not wide spread due to specific limitations like early slower strength gain, poor resistance to flexural, abrasive and impact loading. Authors in this article will present the experimental work to study on effect of polyester fibre in improvement of Impact and Abrasion resistance of HVFA concrete. Experimental study with inclusion of fibre at the rate of 0.15% and 0.25% by mass of cementing material and cement replacement by 50%,55% and 60% with class-F fly ash for design mix M25,M30,M35 and M40 is consider in the present work.
