In this research, the effect of flaxseed oil and paraffin oil as hydrophobic substances used for the protection of coconut fibres against the alkaline medium of cement in structural type mortars was studied. Mortars reinforced with coconut fibre were mechanically characterized by compression and bending tests, which were carried out 7, 21 and 28 days after processing, varying the length (1, 2 and 5 cm) and the percentage by weight of the fibre (0.5 % and 1 % by weight). The results showed that
