Prioritizing the Aggregate Source Based on Particle Packing Density Using Modified Toufar Model and MCDM Methods

Abstract

In concrete works, to obtain optimum packing density it is necessary to attain effective packing of solid particles. Concrete with best maximum packing density (PD) is preferred for construction works as it is strong, durable, and economical. Performance of concrete is affected by type and degree of packing of its constituents. Ideal proportion for concrete depends not only on grading curve of aggregate but also on packing characteristics of fine components. In this paper, the optimization of different sources of the aggregate mix is done to obtain the best packing density using one of the particle packing models, i.e., modified Toufar model (MTM). The objective of this paper is to select the appropriate source of an aggregate of suitable size and in required proportion to get the suitable combination for optimal packing and also to compare the obtained results with the specifications provided in IS 383.
