| titleOfInvention | Method for accelerating the setting of a cement, in particular of sprayable concrete and cement set-accelerator |
| abstract | dem Zement wird neben Zuschlagsstoffen eine erste oder zweite Komponente eines Beschleunigersnzugegeben und durchgemischt, die jeweils andere Komponente des Beschleunigers wird dem Zement in einem zeitlichen Abstandnzur Zugabe der ersten Komponente kurz vor der Verarbeitung des Zements zugegeben,nwelche erste Komponente folgende Stoffe enthält (alle Angaben in Gew-%): n 40- 90 % Calciumhydroxid, 5-50% Calciumformiat und/oder 5-20% Weinsäure, nund welche zweite Komponente folgende Bestandteile enthält:n Aluminiumsulfat oder Aluminiumhydroxisulfat 20-40% Aluminiumhydroxid 5-25% H 2 O 10-50%, und eine Carbonsäure oder organische Sulfonsäure oder deren Salze 5-45%. The invention relates to a method for accelerating the setting of a cement, in particular shotcrete, using an accelerator having at least two components, with the following method steps: the cement is added in addition to aggregates a first or second component of an accelerator and mixed, the other component of the accelerator is added to the cement at a time interval from the addition of the first component shortly before the processing of the cement, which first component contains the following substances (all figures in% by weight): 40-90% calcium hydroxide, 5-50% Calcium formate and / or 5-20% Tartaric acid, and which second component contains the following components: Aluminum sulfate or aluminum hydroxysulfate 20-40% aluminum hydroxide 5-25% H 2 O 10-50%, and a carboxylic acid or organic Sulfonic acid or its salts 5-45%. n n n The invention also relates to a two-component accelerator having the above composition. |
