A Study on Strength of Fibre Reinforced Concrete with Palm Oil Fuel Ash as Partial Replacement of Cement

Samhitha D., Bhanu Pravallika S.

Abstract: One of the main products required in manufacturing concrete is cement, with the increase in the amount of cement used, heat of hydration increases which will lead to the formation of cracks in concrete accompanied by shrinkage effect. To control this, palm oil fuel ash and agro waste which contains some amount of silica act as a pozzolonic material is being used as cement replacement and its strength is compared with conventional concrete of grade M25. Palm oil fuel ash which is obtained by burning palm fruit and dry leaves of palm oil tree in palm oil mills is also used to control heat of hydration effect on concrete, after pulverizing and making into a fine powder. In this study cement is being replaced with palm oil fuel ash in different percentages (5 %, 10 %, 15 %, 20 %) to get an optimum point. From this optimum point the Steel fiber in different percentages (0 %, 0.5 %, 1 %, 1.5 % and 2 %) and glass fiber in different percentages (0 %, 0.1 %, 0.2 %, 0.3 %, 0.4 %). For each set of fibers, mechanical properties were studied by performing Compression test for Cubes, Flexural test for beams and Split Tensile test for cylinders and durability properties were studied by performing sulphate attack test cubes.
