A system for spraying granular pasty matrices onto buildings. A spray gun for a wet mortar which makes possible the easy, safe and efficient spraying of wet mortars including aggregates with a particle size D50 of between 1 and 15 millimeters. The system which it concerns which includes spray gun for wet mortar provided with gun body, with at least one injector emerging in contacting chamber, at least one spray nozzle for mortar, and at least one connection end piece mounted on inlet of body for flow of mortar. Flow of mortar within the guiding duct of body is monodirectional or multidirectional (angular deviation<30°. The position of injection head of the injector in chamber is adjustable. The mortar is constituted by a pasty matrix including aggregates, fillers and additives. The aggregates have a D50=1-15 mm and a form factor F≠1.

The present invention pertains to the discovery that short chain aliphatic fatty acids, such as potassium sorbate, can be used in liquid-additive grinding compositions in the amount of at least 10%, more preferably at least 20%, and most preferably at least 30%, to mill carbonate materials into smaller particle size. The carbonate material can optionally be combined with another inorganic material in the grinding operation, such as limestone, lime, dolomites, talc, titanium dioxide, alumina, and kaolin, ceramics, and cement clinker. The use of the particularly described grinding additive composition are food-grade or food-contact approved, and are believed by the present inventors to resist the humectant behavior of the resultant ground particles which could in herently otherwise decrease efficiency of the particulate grinding process.
