Claim 1
Independent Claim
92 words
A process for the preparation of mortar, such as jointing mortar, characterized in that a silo located on a storage yard or in a storage space for aggregate and binders is filled in such a way that the aggregate and the binder are contained in separate compartments within one silo, which is then conveyed to the building site where the volumetric flows of aggregate and binder are mutually adjusted, whereupon the aggregate and the binder are mixed together with addition of water, yielding the mortar ready for use at the building site.
Claim 2
Dependent Claim

Claim 8
Dependent Claim
39 words
Apparatus according to claim 2, characterized in that the shaft of the conveyor screw for the binder carries a cam against which a plunger rod rests, which rod terminates in the binder compartment and is provided with transverse projections.
