Abstract

In this research work fly ash, iron slag and polyvinyl alcohol fiber was utilized to enhance the strength parameters of the concrete. Fly ash and iron slag were used as replacement of the cement and polyvinyl alcohol fiber was used as an additive at 0 %, 2 %, 3 % and 4 %. After this several samples were casted and then verified for numerous test. Compressive strength test was executed and it finds out that concrete containing Polyvinyl Alcohol fibers (with different curing methods) was showing increasing strength as compared to concrete deprived of Fiber. Specimens of oven cured samples shown a large increase in strength as compared to room temperature curing as shown in the result section. Compressive strength increases up to three percent of adding Polyvinyl Alcohol fiber after that strength decreasing. Flexure strength was carried on the Geo-Polymer concrete with different curing techniques and result show’s an impressive increase in flexural strength, but room temperature cured specimens show lesser growth as compared oven cured specimens. But not lower than concrete which didn’t have Polyvinyl Alcohol fiber in it. Flexural strength increases up to three percent of adding Polyvinyl Alcohol fiber in both the curing techniques and decreases at four percent as shown in the result section. Split tensile test was also carried out for both the curing techniques oven curing and room temperature curing. The samples which were cured in oven curing show impressive growth in strength. Maximum split tensile strength attained at three percent of adding Polyvinyl Alcohol fiber. With the help of UPV, it was found that the concrete that makes with the help of a Polyvinyl Alcohol Fiber is of good quality as shown in results.
