COMPARING STRENGTH PROPERTIES OF POLYPROPYLENE CONCRETE WITH FLY ASH AS CEMENT AND/OR SAND RELACEMENT

Abstract

Research on Fly ash has been done more than 10 years. Though Several researches have been done on the utilization and use of the fly ash in various fields such as construction material, fertilizer, adsorbent, embankment, road pavement etc. But still there is huge amount of fly ash has been disposing on land area which is coming through Coal burning process in electricity generation and various process. We need more options and ways to utilize the fly ash. Fly ash has binding properties which helps to utilizing it with cement in concrete. fly ash can be added up to a limit proportion of cement in concrete. Beyond this limit if we add more fly ash in concrete, the strength of concrete will decrease. Polypropylene fibers are widely using in concrete industry are going very useful. Polypropylene fiber in concrete gives improvement in form of toughness, fatigue, impact resistance, permeability, shrinkage, and wear resistance. In this report the main parameters are investigated for M40 grade concrete with use of polypropylene fiber, fly ash as Cement replacement and sand replacement. In this study, the effect of both parameter polypropylene fiber and fly ash in concrete are evaluated. The combination of these parameters will give a new approach to more utilize the fly ash. The result shows that along with 0.30% of popropylene fiber gives improved strength properties as The use of fly ash as sand replacement along with polypropylene fiber also gives better strength than other proportions. Hence it could provide a commercial feasibility for the fly ash disposal and useful for extra utilization of fly ash.
