Abstract

This research paper mainly focuses on the utilization of Class F-fly ash (by-product of power plant) for production of aggregates by different method. In the present study three different types of methods are adopted for preparation of aggregates. Cold bonding, autoclaving and sintering techniques are the very general technique used for preparation of the aggregates. Sodium hydroxide, Bentonite and Sodium silicate are used as a binder material during the pelletization process. The binder and fly ash proportions of 15: 85, 10: 90 and 17: 83 with water to cement ratio 0.3 are mixed to get the fly ash aggregates. Various mechanical properties of the aggregates such as crushing strength, impact test, abrasion test, specific gravity, water absorption, porosity were determined. The test results shows that the 7 days crushing strength and water absorption value of cold bonded aggregates 6.30 Mpa and 12.25% followed by autoclaving is 5.46 Mpa and 13.10% and sintering are 5.80 Mpa and 5.20% respectively. Overall test results have shown that fly ash aggregate can be used as a possible construction material in concrete world.
