Abstract
The invention relates to a process for producing a composition suitable as accelerator for the curing of cement, by contacting the components aa) at least one component selected from the series of hydraulic binders and/or latent hydraulic binders, and bb) at least one dispersant suitable for the dispersing of inorganic particles in water, and cc) water, the weight ratio of components aa) to cc) being between 1.5:1 and 1:70, wherein the rate ratio of components aa) to bb) is between 20:1 and 1:2. In addition, the use of the composition obtained as hardening acceleration for chemical mixtures in construction is disclosed.
Claims13
A process for producing a composition suitable as an accelerator for curing cement, the process comprising
