IS 2386(2) – 1963 : Methods of test for aggregates for concrete, Part 2: Estimation of deleterious materials and organic impurities CLICK HERE IS 2386(3) – 1963 : Methods of test for aggregates for concrete, Part 3: Specific gravity, density, voids, absorption and bulking CLICK HERE For the same mix design, the recycled aggregate concrete produces almost similar strength compared with the virgin first class brick aggregate concrete commonly used in Bangladesh. In this article, we discuss the properties of the standard aggregates used in the production of concrete as per the American Standards (ASTM- C33/C33M). affects the bond between asphalt binder and aggregate. This could be for a variety of reasons including: susceptibility to change/deterioration. 4 steps of superpose mix design. Teachers. 0.2.1 The requirements for aggregates for mass concrete have been included and it is proposed to withdraw IS: 515-1959*when this standard is printed. Deleterious material (sand equivalency test) - identify amount of clay in fine aggregate. Most research aggregates will be characterized by the Aggregate Image Measurement System for shape, angularity, and texture. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.
