The four aggregates were tested for particle size and gradation by the wet sieve analysis ASTM C-117-67. The wet sieve analysis was used for an accurate account of dust and agglomerations of fines that may be found in highly textured kiln fired aggre gates. The gradation test data for these four aggregates are included in Table 1.
