Prediction of Mix Ratios for Grade 30 Superplasticized Concrete Using Osadebe’s Regression Model
Abstract: This study developed a model for estimating the compressive strength of grade 30 super-plasticized concrete. The regression model was built using a total of 15 experimental mix ratios. The results of compressive strength at 28 days from the concrete cubes were used for model development. Two cubes (150 mm × 150 mm × 150 mm) were produced per mix ratio, totaling 30 cubes for the 15 trial mix ratios. Osadebe’s …
