Abstract

An anti-dust additive composition for industrial mortars, dry coatings, cements and tile adhesives, includes at least a hydrocarbon fluid, a surfactant and 0.01% to 5% wt of water, preferably from 0.01% to 2% wt, more preferably from 0.01% to 1% wt and even more preferably from 0.05% to 0.5% wt of water. A process of preparation of construction material includes the step of adding the anti-dust additive composition to a material powdery binder. The use of the anti-dust additive composition for decreasing the dust emission during the fabrication of construction material with a material powdery binder and/or during the use of the construction material is also disclosed.
