Authentication of Mathematical Models Developed for Properties of Basalt Coarse Aggregate

The coarse aggregate is treated as an inert material and only its physical properties like shape, size, water absorption and specific gravity are studied. Whereas, on increasing the quality of concrete mix, the strength of coarse aggregate also comes into picture. In this paper, effects of all physical properties namely Specific Gravity, Aggregate Impact value (%), Aggregate Abrasion Loss (%), Aggregate crushing Value (%), Soundness Loss (%) 5 cycles in Na2SO4 solution and Water Absorption (%) on concrete properties are discussed. Specific gravity and water absorption of coarse aggregate affect all other properties to an extent. Empirical mathematical models have already been developed between physical & mechanical properties using 14 nos. of basalt coarse aggregate samples. Using these mathematical models, mechanical properties can be determined with physical properties of Basalt coarse aggregates. In this paper, these developed mathematical models have been authenticated.
