USE OF BOTTOM ASH AS FINE AGGREGATE IN CONCRETE: A

investigations been carried out by many researchers to study the use of bottom ash as aggregates in concrete. Effect of bottom ash on the properties of concrete such as workability, compressive strength, flexural strength, are discussed elaborately. Bottom ash use in concrete is becoming more important in view of the fact that sources of natural sand as fine aggregates are getting depleting gradually, and it

Influence of Bottom Ash Replacements as Fine Aggregate

This research focuses on evaluating the feasibility of utilizing bottom ash from coal burning power plants as a fine aggregate in cellular concrete with various foam contents. Flows of all mixtures were controlled within 45 ± 5% and used foam content at 30%, 40%, 50%, 60%, and 70% by volume of mixture. Bottom ash from Mae Moh power plant in Thailand was used to replace river sand at the rates of 0%, 25%,
