Composición ligera a base de ceniza volante
Composición cementosa consistente en: 100 partes en peso seco de ceniza volante de clase C; 2-3,5 partes en peso seco de una sal de metal alcalino de ácido cítrico; de 0,5 a 1 parte en peso seco de silicato de sodio; y agua.
A method of making a lightweight cementitious binder composition with improved compressive strength for products such as cementitious panels is disclosed. The method mixes fly ash, alkali metal salt of citric acid, alkali metal silicate, foaming agent for entraining air, water and in the preferred embodiment a foam stabilizing agent. Compositions which include fly ash selected from the group consisting of class C fly ash, class F fly ash and mixtures thereof, alkali metal salts of citric acid, alkali metal silicates, foaming agents, and preferably a foam stabilizer, such as polyvinyl alcohol, and do not require use of set retarders. Compositions containing class F fly ash can optionally contain Type III Portland cement.
