THE STRENGTH ASSESSMENT OF POLYMER FIBER-INDUCED CONCRETE

Abstract

  Concrete utilization has become one of the basic needs of humans in today’s industrialization and urbanization scenario. Ingredients of concrete include cement, sand and aggregates. Cement production is associated with CO2 emission and green house emission issues. Availability of sand and aggregate is also creating serious issue these days. Handling of concrete required technical expertise and day to day research advancements are made to solve issues related to concrete being weak in tensile strength. Weakness is concrete can be mitigated by adding fibers which help to improve tensile strength of concrete. Fibers are available in the form of waste polythene, discarded rubber tyres of automobiles, etc. Polymer fibers can provide better strength. It increases ductility and reduces deflection in large concrete members of structure. In current work, Polythene and rubber tyres were cut down to fine fibers and added in concrete as replacement to cement in different incremental percentages. M30 grade of concrete was prepared. M30 and above grade concrete are generally utilized in construction of industrial flooring. Different tests performed on polymer fiber induced concrete revealed that it can be suitably used as substitute to normal M30 concrete for temperature and impact resistant flooring construction.
