Abstract

During the production of higher density lightweight concretes filler aggregates can be used instead of the part of the binding material. One type of filler aggregates is active filler aggregates that change the course of the reactions of hydration. The technogenic waste material – catalyst utilised in the reactor of catalytic cracking can be used as filler aggregate. Lightweight concrete (expanded – clay lightweight concrete), with the filler aggregates – technogenic waste materials is analysed in the research. During the analysis, the influence of the filler aggregate on the properties of concrete mixture was identified, thermographic analysis of exothermic effect was carried out, strength, structural properties were analysed, X-ray structural analysis was carried out. Additionally, the analysis of crush resistance of the coarse aggregate is carried out and described during the research. Article covers the information on the changes of the investigated properties in relation to the amount of the filler aggregates.
