This research work is aimed at developing an improved mathematical model which would be used to optimize the compressive strength of Glass Fibre Reinforced Concrete (GFRC) using Scheffe’s Second Degree Polynomial. From Scheffe’s Simplex method the compressive strength of GFRC was determined for different ratios. Control experiments were also carried out and the compressive strength determined. After the test has been conducted, the adequacy of the model was tested using fisher’s f-test. The result of the test shows that there is no significant difference between the model and control results. An optimum compressive strength of 20.71N/mm2 was produced.
