Application of Scheffe’s model in optimization of compressive strength of lateritic concrete
In this research work, the use of Scheffe’s simplex theory for the optimization of the compressive strength of lateritic concrete was investigated. The objective of the study is to develop a model that can predict the mix ratio when the desired compressive strength is known or vice-versa. A total of sixty (60) concrete cubes were cast. For each of the twenty mix ratios, three cubes were cast and the average determined. The first thirty cubes were used to determine the coefficients of the model while the other thirty cubes were used to validate the model (control test). The optimum compressive strength of concrete at 28 days curing was found to be 25.04 N/mm² and the corresponding mix ratio was 0.6:1:1.75:1.75 (water, cement, laterite, granite). The model was found to be adequate for prescribing concrete mix ratios, when the desired compressive strength is known and vice-versa.
