CALCULATIONS 5.1 Calculate the percentage of each or a combination of deleterious materials: PDW ï½ï´100 Where: P = Percentage of deleterious matter by weight D = Weight of deleterious substances, g W = Weight of total sample (retained on No. 4 [4.75 mm] or No. 8 [2.36 mm]), g.est the material retained on the No. 8 (2.36 mm) sieve for compliance with the specification requirements if the sample contains an aggregate that predominately passes the No. 4 (4.75 mm) sieve. 8.7 Remove any material other than coated particles of aggregate that will slake down during the test.

Lutein (from the Latin luteus meaning yellow) is one of over 600 known naturally occurring carotenoids. Found in green leafy vegetables such as spinach and kale, lutein is employed by organisms as an antioxidant and for blue light absorption.Lutein is also found in egg yolks, animal fats and the corpus luteum.utein is a xanthophyll, like its sister compound zeaxanthin. It has primarily been used as a natural colorant due to its orange-red color. Lutein absorbs blue light and therefore appears yellow at low concentrations and orange-red at high concentrations.
