WebStructural grade lightweight aggregates have been extensively used throughout North America for more than 70 years in cast-in-place structural lightweight concretes for high-rise buildings and bridges and are now being widely used for geotechnical applications. Structural grade lightweight aggregates, when used in backfills WebGradation. 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.
