Improvement of properties of aluminosilicate pastes based on optimization of curing parameters

conference paper

Alkali-activated binders represent a low-energy alternative to traditional binders based on lime or cement. In this paper, a new binder of this type is designed and the influence of curing parameters on its mechanical properties, namely 7-days compressive strength, is investigated. The curing parameters include the curing temperature and the period of exposure. To maximize the compressive strength of the binder, simplex optimization procedure is applied in order to demonstrate its applicability for this research. The preliminary results indicate that the procedure is able to reach positive results as the compressive strength is found to increase by ~11 %. As this improvement is achieved already after the first optimization step, it can be concluded that this approach has a potential to be more effective than traditional empirical design which is common in building materials engineering.
