Study on Partial Replacement of Cement Using Pertile Powder and Chalk Powder with Sugarcane Fiber in Concrete

Concrete is a vital part of the construction industry. The expansion in population has placed a massive want for more and more infrastructure and it keeps growing. The result of this demand is that the increase in production of cement. This has in turn led to exploitation of natural resources in addition as emission of pollutants that cause damage to our environment. As a result, waste management has become an enormous problem for our environment. Chalk is the most popular material it is used is a fine whitish colored powder composed of calcium carbonate (CaCO3), a form of limestone and is obtained by fine grinding of limestone. Chalk powder can used as partial replacement of cement because of the fact it has some of the binding properties. Volcanic glass is the source of the lightweight, porous material known as perlite powder. It is produced by heating raw perlite ore quickly to a temperature of around 1600°F (870°C), which causes the ore to expand and produce a large number of small bubbles. Perlite's characteristic lightweight and porous structure are attributed to these bubbles. Sugarcane fiber, also known as bagasse fiber, is the fibrous residue left after extracting juice from sugarcane stalks. It is a natural, biodegradable material rich in cellulose, hemicellulose, and lignin. In concrete technology, sugarcane fiber is gaining attention as a sustainable additive that can improve certain mechanical properties of concrete. The research work here deals with the partial replacement of cement with CP and PP together with addition of sugarcane fiber. After mixing, casting and curing the characteristic strength of this new concrete are compared with standard concrete of M35 grade. The experimental investigations are administered for compressive strength, split tensile and flexural strength for curing period of 7, 14, 28 days. Workability gets reduced at higher replacement of materials and the experimental results shows test are satisfactory up that the combined replacement percentage of 14%, which has 7% CP and 7% PP, and 0.6% SCF the values of compressive strength, flexural strength and split tensile strength were higher compared to alternative replacement percentages.
