To determine the strength of concrete using human hair & corn starch

Abstract

Admixtures are used to alter the properties of concrete. They are introduced to a batch of concrete during or immediately before its mixing . The specific effects of admixtures generally vary with a type of cement & mixed proportion. The benefits of using admixtures are improve quality, improve, workability, improve fibre resistance, increase in setting time&increase in tensile strength. Fibre reinforced concrete provide good flexular strength with less crack development. Since concrete is weak in tension. Human hair are strong in tension, non degradable and is available in abundance, present studies have shown the effect of human hair on cement concrete increase the tensile strength of concrete. Human hair doesn’t harm the environment. Also in addition of human hair enhances the binding properties, micro cracking control, impart ductility and also increases swelling resistance. In this study an attempt has been made to identify the various properties necessary for design of concrete mix by adding human hair.
