This work is aimed at using Scheffe’s Third Degree Polynomial optimization Model, Scheffe’s (5, 3) for five component mixture, developed by Nwachukwu and others (2022a) to optimize the compressive strength of Nylon Fibre Reinforced Concrete (NFRC).The objective is to compare the results with the results of the previous work done on NFRC based on Scheffe’s Second Degree Polynomial, Scheffe’s (5, 2) Model by Nwachukwu and others (2022d). Through the use of Scheffe’s Simplex method, the compressive strengths of NFRC with respect to Scheffe’s third degree model were determined for different mix proportions. Control experiments were also carried out, and the compressive strengths determined. The adequacy of the model was evaluated using the Student’s t-test and the test statistics confirmed the adequacy of the model. The maximum compressive strength of NFRC based on the Scheffe’s(5, 3) model was 29.42MPa (N/mm2) which is higher than 21.96MPa,being the maximum value obtained by Nwachukwu and others (2022d) for the previous work done on NFRC based on the Scheffe’s(5,2) model. However, the optimum strengths obtained from both models are higher than the minimum value specified by the American Concrete Institute (ACI), as 20MPa. Thus NFRC based on both Scheffe’s models can produce the required compressive strength needed in light-weight structures and construction projects such as Bridge, Building pillars, Sidewalks, Building floors, Drainage pipes, Septic tanks etc., still satisfying all the required economic, aesthetic and safety criteria.
