Abstract:

This study investigated the effect of properties of concrete stabilized with coconut fibre (CCF). The following properties were investigated: compressive, flexural, split tensile strength, setting time and workability. 24 concrete cubes and cylinders of size 150mmx150mmx150mm, 100mmx100mmx500mm and 150mmx300mm were cast for both the plain concrete and concrete mix stabilized with coconut fibre. The mix proportion used for the experiment was 1:2:4 batched by weight of one part of Ordinary Portland Cement, two parts of river sand and four parts of crushed granite. The water cement ratio was 0.6. 2%, 4%, and 5% coconut fibre was added to the concrete mix. The control mix had 0% coconut fibre. The compressive, flexural, split tensile strength, were obtained after 7 and 28 days respectively. The workability and setting times of the fresh concrete, containing these percentages by weight of coconut fibre were also determined. The compressive, flexural and split tensile strength decreased as the percentage of coconut fibre was increased at 7 and 28 days respectively. The initial and final setting times and workability of the fresh concrete also decreased as the percentage of the coconut fibre increased.

Keywords:

coconut fibre, Compressive Strength, Flexural Strength, Split Tensile Strength, workability, setting time.
