Description
Summary:Workability is one of the factors that affect concrete strength and durability in addition to the cost of labor and the appearance of the final product. It is a vital feature of the concrete that must be measured properly to ensure the quality of concrete. This paper presents a method for predicting equations for workability of concrete and correlation between the workability tests by using Pearson correlation coefficient. The results show that the developed model is accurate and it can be used for prediction of the workability parameters with a high degree of accuracy. Based on statistical analysis, the correlation was significant at the 0.01 level (2-tailed) between the workability of concrete tests. Regression equation relating compacting factor and slump was based on nonlinear general equations (C= 0.5371S^0.1204) and also nonlinear equations were found between Vebe and slump tests (V = 8.0689e −0.0175x ).
