Based on the fine aggregate gradation in the FAM, the volume fraction of fine aggregates and filler dusts can be separated, which are 64.2% and 8.8%, respectively. To study the effect of the volume fraction of fine aggregates on the dynamic shear modulus test, the air void content and the asphalt mastic property should remain constant.

Key words: SCC, Flowability, Elastic modulus, S/A. ABSTRACT In order to study the effect of sand ratio (S/A ratio, fine aggregate volume/total aggregate volume) on the elastic modulus of self-com-pacting concrete (SCC), concretes with various S/A ratios were cast and tested. Elastic moduli of SCC were compared with those of normal concrete.

The results show that the tensile moduli are approximately 1.0–1.3-times larger than the compressive moduli within the material's first week of age. To enable a direct estimation of the tensile modulus of concrete, a simple three-phase composite model is developed based on random distributions of coarse aggregate, mortar, and air void phases.

The Fine aggregate (Sand) taken is Yamuna river sand and coarse aggregate taken is Dolomite limestone in crushed form. It has been sorted in several categories starting the Fineness Modulus (FM) of sand from 2.0 to 3.0. These were mixed in different proportions to get a consistent combined FM. The combined FM is determined like All-in-aggregate FM.
