Experimental Investigation of Mechanical and Durability Properties of Concrete Containing Nano Silica, Alccofine and Polypropylene Fibers

Received Date:01 February 2023, Accepted Date:04 April 2023, Published Date:12 May 2023


Objectives: To evaluate the strength and durability behaviour of concrete specimens that have been reinforced with micro reinforcements made of polypropylene fibers and microfillers and nanofillers such as alccofine and nanosilica, respectively. Methods: The concrete samples were made to achieve a targeted strength of 33 MPa. In this experiment, polypropylene fibers were added to the concrete mix in volume fractions of 0%, 1%, 0.2%, 0.3%, and 0.4%, with the optimum percentages of alccofine (15%) and nanosilica (1%). Concrete mixes with and without PP fibers were evaluated for their mechanical properties, such as compressive strength, elastic modulus, and flexural strength and also looked at several durability characteristics, including acid resistance, porosity, sorptivity, and water absorption. The proper instrumentation has been used to make the measurements related to the experimental parameters. Findings: After the introduction of Alccofine, Nanosilica, and Polypropylene fibers, the following properties have been improved: compressive strength, elasticity modulus, flexural strength, water absorption, porosity, sorptivity, and acid resistance. Adding polypropylene fibers increased the compressive strength of cubes and cylinders by up to 15.15 and 14.87 percent, respectively. It also increased flexural strength by up to 10.47% and elasticity modulus by up to 14.35%. Novelty: The novel material, comprising polypropylene fibers, significantly enhances the mechanical and durability characteristics of concrete, enabling the concrete to avoid brittle and rapid failure and instead experience a more ductile failure that enhances the durability and serviceability of the concrete.
