Fine Aggregate Specific Gravity, The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water , Typically, aggregate used in HMA production will have a bulk specific gravity between about 2400 and 3000 ,THE NEED FOR STANDARDIZATION OF AGGREGATES FOR ,, Aggregates, both fine and coarse, take about 65-75% by volume of concrete and are important ingredients in concrete production The parent materials of aggregates are derived mainly from volcanic activity The dominant rock for coarse aggregate production in Ethiopia is generally basalt while ignimbrite is most commonlySPECIFIC GRAVITY AND ABSORPTION OF FINE AGGREGATE, fine aggregate loosely in the mold, filling it until overflowing occurs, and heaping additional material above the top of the mold Lightly tamp the fine aggregate into the mold with 25 light drops of the tamper Each drop should start about 02 inch above the top surface of the fine aggregateA Review on Recycled Aggregates for the Construction Industry, The results suggest that both FBA and FRA can be used as fine aggregates for concrete production The properties of RA derived from parent concrete (PC) of three strengths were studied, each of them made with three maximum sizes of aggregat Using these nine recycled aggregates, three strengths of RAC were made and studied ,The Effect of Aggregate Properties on Concrete, Aggregate is classified as two different types, coarse and fine Coarse aggregate is usually greater than 475 mm (retained on a No 4 sieve), while fine aggregate is less than 475 mm (passing the No 4 sieve) The compressive aggregate strength is an important factor in the selection of aggregate.
