Subject: concrete technology Specific gravity and absorption of fine aggregate Experiment No: 5 Name: Rezhwan Hama Karim. Group: B Year of Study: 2019-2020 University Of Halabja. Civil Engineering Department.2nd stage Concrete lap. Contents: Introduction References Purpose Of This Experiment Materials And Equipment Procedure Data analysis Discussion Conclusion Introduction Specific gravity of fine aggregate (sand) is the ratio of the weight of given volume of aggregates to the weight of equal volume of water. But absorbed water is the water that lies close to solid surfaces under the influence of attractive forces References 1. ASTM C127-07, ASTM C128-07a 2. ASTM D75-92 3. BS EN 1097-3:1998 Purpose of this experiment To determine the bulk and apparent specific gravities of fine aggregates so they can be used for calculation of volume occupied by the aggregate in various mixtures containing aggregate, absorption, computation of voids in aggregate.
