Abstract
The development of high strength concretes has increased considerably due to the demand from the construction industry. The requirement of cementitious materials, such as metakaolin, silica fume, fly ash, slag, etc. demands supplementary for replacement of cement. High strength concrete with the use of supplementary cementitious materials is economical as the industrial wastes and byproductsavailable in abundance. Metakaolin (MK) is one of such waste / non-conventional material which can be utilized beneficially in the construction industry.MK is produced by heat treating kaolin, a natural, finely divided, alumino siliceous mineral. By addition of pozzolanic material such as MK, the main properties of concrete like workability, durability and strength can be improved. The HDPE fibers are made from the used plastic jute cement bags, which are free from all debris and maintained uniform aspect ratio. In this studyMK as a partial replacement of cement (15%) and fibers (3%) were added to control concrete,the compressive strength was found to be significantlyincreased for fiber reinforced concrete, MK concrete and fiber reinforced MK concrete up to 17.7%, 22.8% and 27.5% respectively, when compared to that ofcontrol concrete.The Pozzolanic reaction of MK, changes the microstructure of concrete and chemistry of hydration products by consuming the released calcium hydroxide (CH) and further producing additional calcium silicate hydrate (C-SH) gel, resulting in an increased strength, reduced porosity and improved durability. From X-Ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS) and Scanning Electron Microscopy (SEM) studiesit isconcluded that the formulation of more intensity of C-S-H gel and less intensity of portlandite aretogether responsible for the increase in concretestrength.
