Effects of Composite Fiber on Minimizing the Plastic Shrinkage Cracking and Use of AI Tools for Image Detection in Concrete Pavement Structures

Abstract

The use of fibers in concrete structure enhances the structural integrity and reduces its permeability. The present study is focused on the use of composite fibers in the concrete pavement structures to minimize the potential cracking during transition period. For research purpose polypropylene (PP) and steel fiber (SF) are induced as composite fibers (CF) in concrete mix to analyze its effects on potential cracking with aspect ratio, 200 and 70 respectively and effects of plastic shrinkage cracking (PSC) is evaluated. Under the program objective pavement quality concrete of M40 grade was designed with water cement ratio of 0.35% as per IRC SP: 46-2016. Cubes and slab were casted under strict lab quality control and plastic shrinkage cracking and compressive strength were evaluated with different percentages of composite fibers.The result shows that the effectiveness on compressive strength on 7 and 28 days curing from design mix proclaim that adding CF escalate the compressive strength by 15%. shrinkage cracking is reduced up to 99%by adding 0.2 and 0.5% of CF and is highly effective. The Artificial intelligence (AI) Internet of Things (IoT) based machine learning software tool was developed and used for the comparative crack analysis and to plot the results of different cracking pattern
