摘要

Procedure for the obtaining of prefabricated panels employed in the construction of households for chimneys. A mixture is prepared based on a mortar of cement and refractory arids of granulometry less than 20 mm, which also includes a proportion less than 10 per 1000 in the weight of dyes based on natural iron oxides and a proportion less than 1 per 10000 in weight of silicone oils, mixed homogeneously with the aridos. Molding of the mixture is performed by measuring and vibrating the mass in partially flexible wall molds which have its internal surface configured simulating for example bricks and that have machihembrates for its unión to other panels. The gelified mass is left in rest for a period of time of 2 to 6 hours and the scratch of the mortar is performed by immersion in water for a time of 12 to 36 hours, then being proceded to the dismollection of the piece.
