Experimental study on utilization of coal ash to R/C members

Coal ash, produced by coal-fired power plants, is one of industrial by-products against to the environmental conservation. Utilization of the coal ash is an urgent and important objective for the ecological and resources problem. Static loading tests were carried out to investigate shear characteristics of short R/C columns containing high volume coal ash, which included both fly ash and cinder ash. Lateral strength of the columns was able to estimated by the proposed formula for R/C members used normal concrete. The columns had better ductility than the column of the similar shape without coal ash. From these results, it is anticipated that there is strong possibility of using concrete containing high volume coal ash for R/C building structural members.
