The invention concerns a PROCESS for the preparation of cementmortarconcrete compositions or systems,, of a general known type, in which the filler isare comprising or consist of \u201ccalcium carbonate-based filler\u201d, comprising at least one step where the said filler isare treated with an efficient treating amount of at least one treating agent consisting of or comprising superplastifier. The phase controller includes first and second regulators. Based on these selected constraints, the tools may authorize every payment transaction that meets the aggregate constraints without requiring the buyer to authorize every transaction separately. The method generates a remote control signal for controlling the TV set according to the determined hand sign, and controls the TV set to perform a function according to the remote control signal.
