Examining the Compressive Strength Requirement of M-30 Grade Concrete by Adding the Poly- Propylene Fibres in Different Orientation

Abstract

Worldwide, concrete is a very important construction material, impacting heavily on Gross Domestic Products of many nations. In this paper the experimental work carried out for finding the maximum compressive strength in different orientation under taken the standard size of cubes 15X15X15cm. The testing samples are taken for both with and without polypropylene fibers in different Orientation of fibre cause the value of compressive strength. In this study, poly propylene fibres are used to the M-30 grade concrete which is designed as per IRC44-2017 guidelines. Fibres are added in terms of percentage by volume of concrete mould. The percentage of dosage of fibre was 0.3% by volume of concrete mould. There are five type of orientation including layered form were done in concrete matrix and work is to examine the compressive strength of each variety of orientation of fibre and also to observe the function of fibres in holding the concrete through its surface. The failure criteria and the crack orientations are discussed. Examining the fibres appearance before and after the application of load was done.
