| Publication Name | Equations for Mix Design of High Strength Concrete |
| Publication Description | In this study, a model of equations was developed based on tabular data and charts in American Concrete Institute Code (ACI 211.4R.93) to optimize the high-strength concrete mixture design in terms of time, effort and cost. The model of equations was developed with the aid of Microsoft excel sheets after tried various models and choose the most accurate model that adequately represents the data based on the regression coefficient and its predictive capability. The model has the capability of predicting the optimum design of high-strength concrete in an optimum time and it reduces the errors that could happen due to human errors. This model of equations is useful for the adjustment of mixture proportioning of high strength concrete as it can be used instead of data in ACI. Moreover, the validation of this model was performed analytically by design a specific high-strength concrete mixture and compared with the results obtained by the model. The maximum percentage error of the program was about 0.14 % and this is considered a fair result. |
