Abstract
A method for producing concrete parts and a structure includes (i) supplying a first concrete composition based on a quick binder containing Portland cement, curing accelerator system based on Al2O3, CaO lime and SO3 sulphates, a retardant system and a superplasticizer, (ii) adding a releaser system for forming a second concrete composition and pouring the second concrete composition into a concrete form. The use of a releaser system and the preparation of the first concrete composition are also disclosed.
