determined by first water saturating the aggregate (for 24 hours) and then by drying the aggregate so that it becomes water saturated but surface dry. This condition is assessed visually by filling a cone, see figure below, which ten is lifted and the slope of sand cone is assessed.

Sieve Analysis Aggregate gradation (sieve analysis) is the distribution of particle sizes expressed as a percent of the total dry weight. Gradation is determined by passing the material through a series of sieves stacked with progressively smaller openings from top to bottom and weighing the Septic Sand ASTM C-33 Aggregates Division,By using Lafarge Aggregate Division’s Septic Sands that meet the ASTM C-33 gradation you can produce a high quality sewage mound or drainage field that research indicates may reduce the rate of biomat clogging due to fewer fines as com-pared to a sand with additional fines at an equivalent rate. By
Overview. The sand equivalent test (Figure 1) is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils). The term “sand equivalent” expresses the concept that most fine aggregates are mixtures of desirable coarse particles (e.g., sand) and generally undesirable clay or plastic fines and dust (ASTM, 2003{{1}}).TheseInspection & Sampling Procedures for Fine & Coarse ,1-2 5) Templates for belt sampling.
