Identification of Mechanical Fracture Parameters of Alkali-Activated Slag Based Composites During Specimens Ageing
Original language description
The aim of the paper is to present the results of the experiment focused on the development of the mechanical fracture characteristics of alkali-activated slag (AAS) based composites within the time interval from 3 days to 2 years of ageing. Two AAS composites, which differed only in the presence of shrinkage reducing admixture (SRA), were prepared for the purpose of experiments. The composites were prepared using ground granulated blast furnace slag activated by water-glass with silicate modulus of 2.0, standardized quartzite sand with the particle grain size distribution of 0-2 mm, and water. Commercially produced SRA was added into second mixture in amount of 2 % by weight of slag. The test specimens were not protected from drying during the whole time interval and were stored in laboratory at ambient temperature of 21 ± 2 °C and relative humidity of 60 ± 10 %. The prism specimens made of above mentioned composites with nominal dimensions of 40 x 40 x 160 mm and the initial central edge notch were
