An investigation on the effect of sisal fiber on the partially replaced cement with Groundnut Shell Ash in Concrete was carried out. Sisal fiber of 3.5cm length which forms 1% of the mix by weight with groundnut shell ash as a partial replacement for cement was used in preparing the concrete specimen. Compressive strength test was carried out using 0%, 5%, 10%, 15%, 20%, 25% and 30% of Groundnut shell ash as replacement of cement at different curing ages of 7, 14, 21 and 28 days. It was observed that at 7 and 14days of curing, it is needless introducing the GSA since the maximum compressive strength obtained were at 0% GSA. At 21 and 28days of curing, a considerable increase in compressive strength was observed for 5% and 10% of GSA. However, 5% of GSA can be regarded as the optimum content since it gives the maximum compressive strength value of 30.1N/mm2 at 28days of curing. This is followed by 10% replacement of GSA yielding 28.10N/mm2 and then 0% GSA replacement yielding 25.01N/mm2.
