Description of the research topic:
Lime-based renders with nano-additives will be tested during this research. Several renders will be analysed containing various amounts of binder and aggregate. The proportion and type of nano-additives will be also modified causing differences in consistency and properties. The mineralogical composition and physical properties of renders will be tested 1,6,9 and 12 months after casting. The effect of environmental stresses on longevity such as moisture, freeze-thaw and salt crystallization will be also monitored. Non-destructive tests (ultrasonic pulse wave, Schmidt hammer, Duroskop) as well as destructive tests (uniaxial compressive strength, bending tests) will be performed. Besides laboratory analyses test surfaces will be also made and tested on site. Previous tests of special renders show that there are nano-additives which have the ability to master CO2 sequestration via in situ mineral carbonation. From the Hungarian rock types ultramafic/mafic stones are the most suitable materials; therefore tests will focus on these ones. The PhD topic is strongly linked with an ongoing EU funded project (M-Eranet2) which is coordinated in Hungary by the supervisor.
