Possibilities to use municipal solid waste incineration bottom ash in cementitious materials

Abstract

Blended cements whose clinker is partially substituted with other materials have been under intense scrutiny in the last decades. Such binders can provide improved performance regarding consistence, strength, and durability. Moreover, these binders have major environmental advantages such as lower CO2 emissions, the ability to utilise industrial by-products in the manufacture of binder and their lower cost [1-2]. The aim of this work is to analyse properties of municipal solid waste incineration bottom ash (MSWI BA) and to use it as much as possible for the cement-based road binder composition, at the same without compromising constructional characteristics of the hydraulic binder for roads.
