dcterms:description
Since 2003 research work of fly-ash alkali activation has been proceeding. This work is provided by the Department of Construction Technology, Faculty of Civil Engineering, CTU in Prague and the Department of Glass and Ceramics ICT Prague. A very important part in activation process of fly ash grains is the quantity of alkali activator and water. Water is used for preparation of activator solutions, its volume and its quantity is deciding for workability of the mixture. To achieve optimum results it was necessary to search quantity of activators and their concentration in activator solutions that allows required workability. Of course it is necessary to keep mechanical and physical properties of fly ash binder. Quantity of water in activator solutions may be various, but quantity of alkali activators is the same. This paper describes problems with different water ratio in fly ash concrete mixtures especially with reference to concentration of alkali activator solutions.
