Dr Rackel San Nicolas
- Alkali activated materials for constructions (Alkali-activation, Geopolymers, Constructions, Slag, Fly ash)
- Durability of concrete (Durability, Additions, Performance-based approach)
- Smart materials for construction (Self healing concretes, bioconcrete)
Rackel San Nicolas is working to develop reliable test methods for sustainable materials for constructions durability, and to understand the relationship between sustainable concretes microstructure, mechanical, structural properties and durability. She is also developing new smart materials for construction, as biomodified self-healing concrete for examples, using her multidisciplinary background and network.She is working in close collaboration with several industries.
