Method for premixing and addition of fibres in the dry state

Abstract

The process is described for the dry mixing of fibers of different types and sizes with materials formulated with cementants or agglutinant components, granular aggregates and able to include or otherwise other additional ingredients. The principal characteristics of the process are to ensure a correct incorporation of the fibers with the rest of the materials, increase the mechanical fastening of same with the rest of the components and facilitate the use of formulas with high fiber content (over-fibration).

Description

technical field [0001] The method relates to the production of premixed products for use in the fields of art, construction, engineering and industry, in particular containing cements and / or adhesives or adhesives, and fine particles in a loaded or dry and inactive state. Various products of aggregates and / or heavy aggregates, usually powdered or granulated products prior to activation in order to initiate their hardening process. In particular, these materials can be fibrillated, microfibrillated and / or multifibrillated, as well as microstructured and / or prestructured, any of which is applicable, using this method. [0002] The invention also increases the content of fibers in the material, hereinafter referred to as "overfibrillation", although due to its state of the art, an amount of fibers significantly lower than the recommended amount is used. Excessive fibrillation has nothing to do with inhibiting the generation of fissures and microcracks in the initial and subseque...
