TO STUDY STRENGTH CHARACTERISTICS OF PAVEMENT QUALITY CONCRETE BY FRACTIONAL SUBSTITUTION OF GGBS, METAKAOLIN AND WASTE MEDICINE WRAPPERS
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
Pavement Quality Concrete (PQC) is that concrete which is used for highway and road construction .Due to high strength, better serviceability and economy. Now a day’s engineers are much focused on development of pavement which could be effective in long run. The attempt of this learning was to develop M40 PQC mix including GGBS and Metakaolin as fractional substitution of cement as well as waste medicine wrappers as fractional substitution of fine aggregates in the concrete mixes. In this study cement was fractionally substituted with Ground Granulated blast furnace Slag (GGBS) at 10%, 20% and 30% whereas Metakaolin was kept constant at 15% as well as Fine Aggregates was fractionally substituted with waste medicine wrappers at 15%, 10% and 5% in the different design mixes. Concrete cubes, beams and cylinders were casted and tested after 7 days and 28 days. The compressive, flexural and split values for PQC mixes for different percentage of substitutions were reported. The Ultrasonic pulse velocity test and SEM were also performed. From study, it was concluded that for fractional substitution of 20% GGBS and 15% Metakaolin with Cement by weight and 10% Waste Medicine Wrappers with Fine Aggregates (FA) by weight, obtained the utmost value for compressive, flexural and split tensile . Further it was accomplished that with increase in waste medicine wrapper content, ahead of 10 %, strength decreases.
