Concretes based on solid residues from fluidized bed combustion

By Michaela Darakevová

Abstract

The work is focused on the possible use of secondary raw materials of the energy industry in the construction industry, particularly in concrete applications, where as the main raw material of the binder composition are used solid fluidized bed combustion residues - filter and ground. The aim of this work is to prepare concrete or concretes based on solid residues from fluidized bed combustion, that will fulfill or at least approximately approach by their parameters to commonly used concretes based on portland cement. The experimental part is divided into several chapters, at first the results of analyzes of feedstock and solid residues from fluidized bed combustion, portland cement and calcium hydroxide. Other chapters describe proposals for alternative binders, concrete, characterization and testing. Mainly were observed changing properties of the prepared concretes by changing the ratio of binders and aggregates. In tests were evaluated mainly mechanical properties and phase composition
