Verfahren zur Regelung des Hydratationsverhaltens von Gips bei der Verbundwerkstoff-Herstellung

The description refers to a process for the controlled influencing of the relationship between the hydration time (HT) and the opening time (OT) in the production of composite materials. The material mixture from which the panels are produced consists of hydratable calcium sulphate, in particular gypsum binding agent, aggregates, fibres, additives for water and other additives. The ratio (HT:OT) is smaller than 1. This is achieved by adding a delayer-accelerator combination in conjunction with the effect of pressure. The result is a maximum shortening of the hydration time in relation to the open time relating to the manufacturing process.
