Possibilities of Using Clinical Waste Combustion Products as an Aggregate in Manufacturing Construction Materials

Abstract:

In recent years there has been an increasing tendency to use wastes in manufacturing construction material. Some of the studies were dedicated to recycling hazardous waste in a manner that is safe and protective of human health and the environment. The aim of this work is to study the possibility of using clinical waste as the aggregates for manufacturing construction materials. For that purpose, firstly a technology of initial sterilization with combustion of clinical waste was considered. Secondly as along as the clinical waste became sterile and environmentally safe, non-hazardous fractionated products of clinical waste combustion were proposed as aggregate for concretes. This study reports the results of the experiment when different concrete compositions with such aggregate were obtained, investigated and tested using samples (100 mm cubes). Physic-chemical properties of the material were described; its environmental impact was assessed. Thirdly, the potential of the big city in clinical waste generation and subsequent use of fractionated products of clinical waste combustion in construction materials manufacturing was evaluated. As a result of the use of ArcGIS ESRI geoinformation system, a visual representation of the information has been provided. The results of this study show the possibility of using non-hazardous clinical wastes combustion products in manufacturing construction materials and also in road construction.
