New concrete curing compounds and their application to road construction in Austria

Paper by SOMMER from ISCR 5th 1986 Aachen Germany

The curing compounds hitherto employed have not always been found satisfactory when applied to road concrete with superplasticizer, to concrete on small jobs, to concrete placed by slipforming and to cement-boundsurfacings. For this reason three new types of curing compound have been introduced, namely, compounds which - give good protection against loss of water by evaporation and against early shrinkage cracking when sprayed on the very fresh concrete surface; - form a strong membrane within a few minutes which protects the fresh concrete against damage by pelting rain; - form a membrane which can subsequently be pulled off, so that after the very young concrete has been protected against the loss of water it is possible to follow this up with wet curing.
