| Abstract: | This paper presents the experimental investigation carried out to study use of pond ash in concrete. Now a day it is important to think about effective utilization of pond ash to preserve natural resources and to have sustainable development. The concrete was prepared with different percentage of pond ash (15, 25, 35, 45 and 55 %) and it was tested at different ages (3,7,28,56,90, and 180 days). Results of pond ash concrete were compared with control concrete. For all proportions slump in a range of 100-120 mm was maintained. A property of pond ash concrete in fresh state and hardened state was tested. IST and FST of pond ash concrete goes on increasing as replacement level of pond ash with cement increases this is because of less content of cement. Also it is found that rate of increase of compressive strength at early ages mainly 3,7 and 28 days was low and during later age this rate was faster. This shows that later age strength of pond ash concrete is very good and has a scope to use in concrete which are of great importance in the present context of sustainability in the construction field. |
| Description: | Lot of research has been carried out to use alternative material in concrete so as to satisfy various properties of concrete. Pond ash is one such alternative material which can be effectively used to replace the natural material. When coal is burned mainly fly ash and bottom ash is produced. The fly ash is collected by Electrostatic precipitator process. The ash which is fall at the bottom of boiler is mixed with water, and then it is carried away from plant through pipes and finally dumped on open land. After evaporation whatever ash remains is called pond ash. The use of pond ash limited by technical and other concern, in structural concrete but it can be conveniently used in geotechnical and highway constructions, mass concrete construction, earth fill, encouraging the use of huge amount of pond ash generated from thermal power station. The power generation in India is likely to go up from 1,12,090 MW to 2,12,000 MW in the year 2012 [1]. Every year about 65 to 75 million tonnes of ash continue to remain unutilized and dumped in ash ponds and the quantity of ash in ash ponds has increased from about 450 million tonnes in 1999-2000 to more than 900 million tonnes in 2005-2006 [17]. For disposal of this ash requires huge valuable land which may be agricultural or forest. Dr. Yashpal Singh (2011) [12] state that by the year 2015, the disposal of coal ash would require 1000 square km. area or one meter square of land per person in India. The disposal of Pond ash is a big challenge to all as concerning to their quantity which is increasing day by day. Hence worldwide investigation was performed to find alternative use of this waste material and its use in concrete as a partial replacement of cement is one of the effective methods of utilization. The possibility of utilization of thermal power plant byproduct i.e. pond ash as replacement to cement in concrete is taken into consideration. |
