HOW TO DECIDE MAXIMUM SIZE OF COARSE AGGREGATE TO BE

Mar 23, 2015 · For the same strength or workability, concrete with large size aggregate will require lesser quantity of cement than concrete with a smaller size aggregate. In a mass concrete work the use of larger size aggregate will be useful due to the lesser consumption of cement. This will also reduce the heat of hydration and the []

A GUIDE TO DETERMINING THE OPTIMAL GRADATION OF

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.

Gradation Test Pavement Interactive

Overview. The gradation and size test (Figure 1) is used to determine aggregate particle size distribution. Size distribution is perhaps the single most important aggregate quality associated with the control of HMA mixtures. Aggregate gradation and size affect HMA volumetric properties as well as mixture permeability and workability.
