STRENGTH DEVELOPMENT OF SELF-COMPACTING CONCRETE INCORPORATING HIGH VOLUME OF CALCAREOUS FLY ASH
In this paper the strength development of self-compacting concrete with high volume of calcareous fly ash was investigated. The ultrasonic pulse velocity was also measured and relationships between these were investigated. The results show that compressive strength of the self-compacting concrete samples decreases by increasing the fly ash content in the early period, but with increasing the age of samples the reduction of compressive strength becomes lower. The results further indicate that there is very good correlation between compressive strength and ultrasonic pulse velocity of the samples after 14 days or more.
