Abstract: The paper focuses on the study of the properties of cement-based composites produced using secondary crystallization (crystalline additive). In this study, cement mortar made with secondary crystallization was exposed to an aggressive environment and the influence of secondary crystallization on the degradation of the cementitious composite was investigated. The results indicate that the crystalline additive contributed to increasing the resistance of the cement-based composite to the attack of the selected environments (sodium sulphate solution and ammonium chloride solution).
Abstract: This paper deals with a proposal of a new
methodology for durability assessment of solidification product for
its safe further use. The new methodology is based on a review of the
current state of assessment of treated waste in Czech Republic and
abroad. The aim of the paper is to propose an optimal evaluation
methodology for verifying properties of solidification product to
ensure its safe further use in building industry.
