Abstract
The present invention refers to a hydraulic binder made from Portland clinker containing calcium fluoroaluminate 11CaO.7Al O .CaF , to which sodium aluminate, lime, and optionally, sodium bicarbonate are added. The added lime has not undergone the formation process of clinker. The cement mix that can be obtained with this binder has a very short hardening time, scarcely influenced by temperature variations during laying operations.
