Geotechnical and Chemical Engineering Properties for Incinerated Ash and Mixtures

Abstract

India is reeling under huge pressure of managing its quantum of waste because of its direct proportionality to the population of the country. Once it is generated, the next step is to dispose it by any prevailing or advanced methods that are practiced for waste management. The real challenge lies in the huge cost that is incurred while disposing it of by any method. To overcome from the cost burden, mostly landfills serves as the end phase of waste management. The issue that rises from such practice is the use of huge land area just for dumping waste and with time, the availability is also reducing at a fast pace. The paper aims at reducing the flow of end materials going to landfills by focussing on the properties of incinerated ash. In this paper, incinerated ash with its physical, chemical, and geotechnical engineering properties are discussed to find the reuse. The paper also aims to introduce to the generation of biomedical incinerated ash and divert the attention toward its management as well. The paper discusses on “ash in its received form (A-R)” behavior and interaction with soil and with clay. The paper highlights tests which are important to understand the engineering properties of the mixture before reusing those in any building industry.
