Use of Chalcedonite Powder as a Supplementary Material in Lime Mortars
Popis výsledku v původním jazyce
This paper presents a study on partial replacement of lime binder with chalcedonite powder with the purpose of exploring a new application of this waste dust as lime mortar additive. Chalcedonite powder is formed as a by-product of the treatment of mined stone containing chalcedony as the main mineral. Standard air lime mortars were made by incorporating from 0% to 40% of micronized chalcedonite powder in replacement to lime and their mechanical performances, microstructure, and durability were determined. Despite the fully crystalline nature, the chalcedonite powder showed an unusually high pozzolanic activity predicting an improvement in the mechanical properties and durability of lime mortars. As the replacement level in lime mortars increased, the amount of mixing water needed for the same mortar consistency decreased, and the performance properties of the mortars improved. The increase in strengths of mortars was manifested in the long term of 180 days. The progress in mortars carbonation, as well as the pozzolanic reaction of chalcedonite powder, led to the formation of denser, less water absorptive, and more frost resistant structure in air lime mortars.
