For a lean mortar a small admixture of fine sand with the coarse is beneficial If very fine sand is the only kind available the mixture must be excessively rich in cement and a smaller quantity of the sand in proportion to the gravel or stone may be used To secure great density and practical water-tightness of concrete a larger percentage...

AGGREGATES FOR CONCRETE E1-3 sieve and predominantly retained on the 75 181 m No 200 sieve is called fine aggregate or sand and larger aggregate is called coarse aggregate Coarse aggregate may be available in several different size groups such as 19 to 475 mm 3/4 in to No 4 or 375 to 19 mm 1-1/2 to 3/4 in...

In this test method we will determine the relative density ie specific gravity and the water absorption of the coarse aggregat The knowledge of the specific gravity is important for the concrete technologist to determine the properties of concrete made from such aggregat...
