Examine the Carbonation Depth of Concrete Containing Basalt Fibers and Fly Ash

According to a study undertaken by the governments of various countries, buildings built between 1961 and 2000 are now showing notable signs of deterioration. It's clear how an aggressive workplace affects the likelihood of failure. Given the concerns regarding the durability of concrete, this study aims to determine how carbonation affects the concrete's characteristics. This investigation was conducted on an experimental examination to examine carbonation's effects on the mechanical characteristics of ordinary Portland cement (OPC) and concrete that contained varying amounts of fly ash and basalt fibers by weight replacement. OPC with a constant water/cement ratio of 0.46 is used in this study. Depth of carbonation using phenolphthalein solution is measured to observe the effect of carbonation. The present study adjudged that from all basalt fibers and fly ash-based mix combinations the mix combination MB5F20 was adjudged as the most optimum mix combination in terms of increasing compressive strength, split tensile strength, and decrease in carbonation depth.
