Original Abstract

Combination of fine ground granulated slag with proper alkaline activators gives alkali-activated slag (AAS) – a material with remarkable properties. The properties of alkali-activated slag mortars are significantly affected by the curing of the samples. Due to this fact, the main aim of experimental part was to monitor the properties of AAS samples stored for various periods of time in water and in laboratory conditions (temperature 20 ± 2 °C, relative humidity 45 ± 5%). The influences of curing conditions and parameters of mechanical properties and microstructures of AAS were studied and discussed in this paper. The results indicated that the impact of wet conditions was very positive on the level of shrinkage, mechanical strength and homogeneity of the structure. Storage of samples in the laboratory conditions had a rather negative effect on alkali-activated slag. It was also proved by impact-echo and ultrasonic measurements.
