Pond Ash: An Alternative Material as Fine Aggregate in Concrete for Sustainable Construction Bharathi Ganesh1,a, H.Sharada Bai2,b , R.Nagendra3,c and Shivram Bagade4,d 1Assistant Professor, Department of Civil Engineering, Global Academy of Technology, RR Nagar, Bangalore – 560098, Karnataka, India 2Professor, Faculty of Engineering – Civil, Bangalore University, Jnanabharathi Campus Bangalore – 560056, Karnataka, India, 3Technical Director, Civil Aid Technoclinic Pvt.
This paper summerises various characteristics of Pond Ash as fine aggregate in concrete with its engineering properties such as its shape, gradation, texture, physical, chemical and also morphological aspects when used in concrete.
Some of the engineering properties are of particular interest when Pond Ash is used as an aggregate in concrete, being very close to the range of natural resources.
Loss on ignition, percent by mass, (Maximum) 0.52 < 5 Pond Ash as fine Aggregates in concrete possess somewhat unique engineering properties and characteristics when compared to more conventional sources of aggregate materials.
