Strength and Durability Study on Polypropylene Fibre Reinforced Ternary Blended Concrete Containing Alccofine and Zeolite.

Abstract

The study was an experimental evaluation of the strength of concrete incorporating Alccofine, Zeolite, and Polypropylene fibres. Zeolite (10%) and Alcofine (15%) have been used in place of cement in this study. Trials have been conducted to determine the optimum combination. As a fine aggregate, a mixture of natural river sand (55%) and M-Sand (45%) was used. For all the mixtures, the water to binder ratio was kept constant at 0.5. Volume fractions of  0.1%, 0.2%, 0.3%, and 0.4% of polypropylene fibres were added. Through a typical testing approach, the mechanical and durability characteristics of concrete, such as compressive strength and water absorption, were determined for concrete mixes with and without PP fibres.According to the test results, adding polypropylene fibre to a cube and cylinder increased their compressive strength to a maximum of 15.15% and 14.87 % respectively, and decreased water absorption to 0.13%.
