Abstract
The need for sustainable and durable construction materials has led to the use of supplementary cementitious materials and synthetic fibers in concrete. The use of fly ash and polypropylene fibers (PPF) could improve the mechanical properties and durability of the concrete while also reducing the environmental impact of concrete production. Flyash and fibres are the recognised replacement which can add to the unique properties to the Portland cement, The use of these replacements have expanded its utilisation in cement and concrete technologies. The study intends to propose the effect of flyash and polypropylene replacement level on the cementing efficiency with experimental examination. The experimental investigation and the test procedure adopted to study the effects of fly ash induced PPF reinforced concrete includes six different tests. The durability was also accessed in terms of chemical resistance. Three chemical resistance tests were also performed namely acid attack test, sulphate attack test and chloride attack test. Addition of flyash and fibre showed reduction in the workability of concrete and marginal decrease in compressive strength also. However, incorporation of these two as a replacement showed substantial improvement in impact resistance and dynamic modulus of elasticity as well. The maximum strength is achieved by fixing the flyash percentage as 30% and keeping the PPF percentage at 0.2. Sorptivity test and permeability test indicated a decrease in water absorption and permeability for the flyash induced PPF concrete.
Keywords: Flyash, PPF, compressive strength, concrete, durability.
