Event Title

Effect of fly ash on setting times of concrete Comparison of result by using Kosovo’s and Japan’s fly ash

Session

Civil Engineering, Infrastructure and Environment

Description

Coal fly ash is discharged from coal-fired plants and it is expected to be used in industrial world. However, it's known that fly ash highly resembles to cement characteristics in its chemical properties and also physical composition. In light of this fact, this study intended to develop further. So, the objective of this research is to investigate the using of fly ash in producing concrete by replacing of cement content in different percentage and the focus in this paper is analysing the effect of fly ash on setting time of cement also comparing results achieved by using Kosovo’s and Japanese’s fly ash. The research conducts fly ash’s basic chemical and physical properties, setting time for various contents of fly ash and also comparing results for both cases. All results are based on experimental tests according to ASTM and entire work took place in concrete laboratory in Japan. To develop this research 20 different mixes underwent to the testing procedures and results are compared by charts.
