Research Abstract

Recycling of coal ash produced by coal-fired power plants is recently a very significant objective for the environmental conservation. Utilization of coal ash, including both fly ash and cider ash, to reinforced concrete (RC) members for building structures was proposed in this research, in order to consume the large quantity of this product. Experimental studies mentioned below were carried out to estimate mechanical and seismic characteristics of real size concrete and RC members containing high volume coal ash. Test results indicated that there was strong possibility of using concrete containing high volume coal ash for RC building structures.
1. Distributions of material properties in a full-scale concrete column containing high volume coal ash
Material tests of concrete cylinders sampled from a full-scale concrete column containing high volume coal ash by core borings were executed in order to estimate the distributions of mechanical properties in a real size column. Those results were compared with test results of concrete cylinders cured in standard procedures.
2. Full-scale tests of RC columns containing high volume coal ash
Three full-scale RC columns were constructed for this study, while considered parameters were coal ash content and concrete strength. Those columns, of which the section was 800mm square and the height was 2.4m, were designed as flexural failure types according to the current seismic code. Axial loading tests revealed that compressive characteristics of those columns were similar regardless of coal ash content. Test results of lateral loading tests confirmed that full-scale RC columns containing high volume coal ash had sufficient seismic performances, such as lateral strength, ductility and energy dissipation capacity.
