Abstract
"MATERIAL COMPREENDENDO UMA MATRIZ INORGâNICA COMO CIMENTO, ARGAMASSA, GESSO E CONCRETO, REFORçADO POR FIBRAS E PRODUTOS DE TIPO FIBROCIMENTO". A invenção refere-se a materiais compreendendo uma matriz inorgânica tal como cimento, argamassa, gesso ou concreto reforçado por microfibras, que podem ser utilizadas em diversos tipos de produtos, tais como materiais de construção, por exemplo, pisos, telhas, reservatórios de água, e tubulações, em particular para o escoamento de águas usadas. Em particular, as microfibras de poliamida de reforço do cimento da invenção apresentam preferencialmente um título inferior ou igual a 1 dtex, um módulo elástico superior a 1 GPa, um alongamento à ruptura compreendido entre 8 e 100% e uma tenacidade compreendida entre 30 e 100 cN/tex. O alto módulo destas microfibras aumenta a tensão após ruptura dos produtos e permite uma ductilidade maior. As fibras de reforço são fiadas em fundido uma vazão reduzida através do capilar e depois submetidas a taxas elevadas a fim de se obter fibras de alto módulo e de baixo título."MATERIAL UNDERSTANDING AN INORGANIC MATRIX AS CEMENT, MORTAR, PLASTER AND CONCRETE, STRENGTHENED BY FIBERS AND FIBROCYMENT PRODUCTS". The invention relates to materials comprising an inorganic matrix such as cement, mortar, plaster or microfibre reinforced concrete, which may be used in various types of products, such as building materials, for example floors, tiles, water reservoirs. , and pipelines, in particular for waste water runoff. In particular, the cement reinforcing polyamide microfibers of the invention preferably have a titer of less than or equal to 1 dtex, an elastic modulus of greater than 1 GPa, an elongation at break of between 8 and 100% and a toughness of between 30 and 100. cN / tex. The high modulus of these microfibers increases the stress after breakage of the products and allows greater ductility. The reinforcing fibers are spun into a reduced flow through the capillary and then subjected to high rates to obtain high modulus and low titer fibers.
