Abstract
Shape and texture of aggregate is one of the major parameter that influence the properties of fresh and hardened state of concrete .The present methods on mix proportioning of normal concrete have incorporated shape characteristics of aggregate. Since the classification of aggregates is very broad .It often leads to inconsistent results and the property of concrete varies. Thus quantification of these properties is essential to further rationalize the process of concrete mix proportioning. Various codes have envisaged certain tests that indicate the shape characteristics of aggregate. Flakiness index, Elongation index and angularity number, Index of aggregates particle shape and texture (IAPST). An elaborate study covering fine aggregates with different size, grading, shape and texture characteristics is essential. However, this paper deals with the study of the influence of shape and texture of fine aggregate (natural sand, stone dust) on concrete mix proportioning. Experimental investigation was done on fine aggregate with different shape and texture characteristics, water cement ratio, water content, and coarse aggregate content for the study. Aggregate of 10 mm and 20 mm from single source as coarse aggregate and 53 grade (28 days strength of 53 Mpa) ordinary Portland cement are considered as the constant parameters.
