Method for producing precast prestressed concrete slabs with increased fire resistance

摘要

process for the production of prefabricated concrete panels spru0119u017canych enhanced fire resistance and different lengths, for construction of concrete dcnf characterised by this,that the individual components of mixtures of percentage, mixed in the first mixing stage.what is simultaneously mixed with aggregates prepared acrylates modified nanostrukturalnie, subsequently dosed is cement cem and 42 r with cem and 42.5 n sr3 on,and at the end the following quantity based on multikarboxylatu00f3w and the polymeric fibers that undergo fragmentation and dosing together with sand and kruszywem,and, after mixing, make transporting to leu in mieszalnikiem, which follows her release while forming process by forming the external and internal longitudinal channels.then formed record covers paroizolacyjnu0105 foil and heats the lower part, then undergo a maturation process and subjected to cutting length.
