Recycling of bottom ash and fly ash wastes in eco-friendly clay brick production

Abstract

The use of waste-based materials in the construction industry has received significant attention in recent years to develop environmentally-friendly construction materials. This paper presents an experimental study on the properties of bricks containing clay, fly ash (FA), and bottom ash (BA). A total of 12 batches of bricks were manufactured and experimental tests were conducted at two firing temperature of 950 and 1050 °C to determine the apparent porosity, water absorption, apparent specific gravity, bulk density, compressive strength, and thermal conductivity. Microstructural analysis was undertaken to describe the reasons for the obtained experimental results. The results show that the ..
