Abstract

Cement is the most important ingredient of the concrete which produces carbon dioxide which is May harmful. So it is a main concern to reduce the usage of cement. The increase in price of the cement not only will increase the budget of a construction however additionally poses a significant threat to the country’s development. It’s known that some waste product like nano silica and metakaolin are having some building material and siliceous properties. The impact of carbon dioxide emission due to production of Portland cement can be reduced by partial replacement of cement with supplementary cementitious materials. Nano silica and metakaolin like waste materials comprise pozzolanic properties but their disposal is causing acute environmental setbacks. This project work is carried with sets of objectives, viz., and effect of metakaolin, nano silica and nylon on properties of M35 grade of concrete with different proportions of cement with metakaolin and nano silica together with 0%, 1%, 1.5%, and 2% of nylon fibers. Nylon was the first truly synthetic fiber to be commercialized. Metakaolin to replace cement in various percentage levels is 10%, 20%, 30% and 40%. The present project involves a comprehensive laboratory experimentation study for the application of new waste materials in the preparation of concrete. The main objective of investigation is to study the strength behaviour i.e. compressive strength and impact resistance of concrete with different percentages replacement of cement with metakaolin and nano silica and to study the tensile behaviour on adding with nylon fibres.
