ABSTRACT:
In the preparation of a cement paste about 30 to 76% of the total water is added to the cement to form a funicular state, capillary state or slurry state, and the resulting mixture is kneaded so as to reduce the coagulated lumps of cement. Then the remaining quantity of water is added and the composition or mixture is kneaded again. Sand and/or gravel may be incorporated after the firstly kneaded mixture. The resulting cement paste, mortar or green concrete exhibits a small percentage of bleeding water and products prepared therefrom have a high compression strength.
