Importance of Aggregate Gradation of concrete slab

Importance of aggregate gradation for concrete slab. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two

A GUIDE TO DETERMINING THE OPTIMAL GRADATION

This guide provides a means to determine the optimal gradation of sand and coarse aggregate materials for highway concrete pavements. The guide is, to a major extent, based on the use of a computer model (1, 2) developed by G. M. Idorn Consult A/S (GMIC) for estimating the porosity remaining after the packing of fine and coarse concrete aggregate.
