A Comparison Study on Mechanical Properties by Using Polyesters and Polypropylene Fiber Concrete

EasyChair Preprint 12296

Abstract

Right now, concrete is used in the greatest volume of construction projects, and the near future, there won't be any other options available. It is necessary to develop better quality concrete that will survive longer and have increased mechanical qualities to extend the service life of any structure since enormous volumes of concrete are being utilised for new construction work. It is not possible to change its innately breakable nature or the requirement for any concrete structure's tensile strength. Fiber-reinforced concrete (FRC) appears to be a feasible substitute under these circumstances. The practical application of polyester and polypropylene fibre (pp) as secondary reinforcement in concrete to alter its brittle properties is the main topic of this research paper. The M40 grade of concrete was employed in this investigation. As a result, different proportions of polyester and polypropylene fibre were added to the concrete. such as 0.32, 0.37, 0.42, and 0.47 by the concrete's weight, in that order. To investigate the usage of polyester and polypropylene fibre in concrete, a series of controlled lab tests were conducted. For compressive and flexural strength, only the basic concrete mix is evaluated in the first sample. The second sample is evaluated for compressive strength and flexural strength again after 0.32, 0.37, 0.42, and 0.47%, respectively, of polypropylene fibre, are added to the concrete mix. The polyester and polypropylene fibres were tested in the third concrete sample in the same way. which demonstrates how adding fibre to concrete can raise its quality.

Keyphrases: Polyester fibre, Polypropylene fibre, Split tensile strength, flexural strength
