Abstract: Results of experimental investigation carried out to study on impact strength of fly ash aggregate concrete are presented in this paper. Aggregate is most widely used in reinforced concrete construction. In this investigation, fly ash aggregates were used in concrete and Impact strength of fly ash aggregate concrete will be studied.
In cold bonding the pozzolanic behaviour of fly ash is used. As a binder, lime or cement is applied, and optionally additions of calcium sulfate or sulfite. For each type of bonding one aggregate is evaluated. The fly ash aggregate processed on a sintering grate showsthe best quality and also has the lightest weight.

fly ash, slump, compaction factor. INTRODUCTION Sustainable materials are currently widely considered and investigated in construction engineering research. Some examples of sustainable research worldwide are the use of recycled concrete aggregates, coal fly ash, ground clay brick and pervious paver block system.
Lignite or subbituminous fly ash contains up to 30 percent or more calcium, compared with anthracite or bituminous fly ash, which may only contain 4 to 6 percent of calcium. The use of high calcium fly ash may improve asphalt stripping with many aggregates, although there is not a great amount of field performance data to corroborate this .
