ARTIFICIAL LIGHTWEIGHT AGGREGATE MADE WITH NGHI SON FLY ASH

Le Phuong Thanh

Tóm tắt


The study focuses on the production of fly ash lightweight aggregate. The basic physical properties and mechanical characteristics of lightweight aggregate produced are analyzed systematically. Factors affecting the efficiency of pelletization process such as type of binder, moisture content, process duration and alkali content are evaluated. Further, characterization of aggregates was evaluated based on the specific gravity, gradation, density and aggregate crushing strength. It is observed from the test results that different aggregates were found to be maximum when the angle of pelletizer is set to 36 0 with a speed of 55 rpm.
