Document Type and Number:
Japanese Patent JPS61500842
Kind Code:
A
Abstract:
The present invention relates to a process for the quick and controlled setting of a hydraulic binder containing both Portland cement and alumina cement. Furthermore the invention relates to a hydraulic binder, optionally in a mixture with an aggregate and/of reinforcing material, for use herein, as well as to a process for the manufacture of building elements using such a hydraulic binder. According to the invention a composition comprising Portland cement and alumina cement in a weight proportion of from 3:1 and 10:1 and an additional amount of a calcium compound of from 0.5 to 5%, by weight, based on the dry weight of Portland cement plus alumina cement, is prepared, water is added to this composition and the slurry obtained is allowed to set. Generally also an aggregate, such as sand, will be added to said binder composition. Preferably fly ash is added too. The use of an acid, in particular citric acid is advantageous.
