U S and Metric Sieve Sizes

* Not a standard ASTM size Sieve mesh sizes are based on dimensions of the mesh size opening or on the number of openings per linear inch The two major standards governing test sieves and appropriate sizes are ASTM E11 and ISO 565/3310-1 both of which specify parameters for aperture dimensions mesh size and statistical variations Step 6 Determine Coarse Aggregate Content Using Table 12-4 (PCA Design and Control of Concrete Mixtures) 1 inch aggregate and a FM = 2 8 the bulk volume of coarse aggregate per unit volume of concrete = 0 71 Therefore the weight of the course aggregate = 0 71 x (27ft3/yd3) x (103 lb/ft3)
