Tecwool\u00ae F - Prote\u00e7\u00e3o elementos estruturais de bet\u00e3o<\/h1>

Presente na maioria das edifica\u00e7\u00f5es modernas, o bet\u00e3o forma parte da nossa paisagem por conta das suas m\u00faltiplas aplica\u00e7\u00f5es. Entretanto, a solidez do bet\u00e3o v\u00ea-se seriamente reduzida na presen\u00e7a do fogo, o que compromete a sua resist\u00eancia quando a temperatura ultrapassa os 300\u00b0 C e perde-a quase por completo a partir de 550\u00b0C. No caso do bet\u00e3o armado, a resist\u00eancia das armaduras diminui a partir dos 250 \u00b0C, o que produz danos na ader\u00eancia entre o a\u00e7o e o bet\u00e3o.<\/p>\n
mcr tecresa\u00ae<\/sup>\u00a0<\/strong>comercializa a argamassa Tecwool\u00ae <\/strong>F, ensaiada segundo a norma UNE ENV 13381-3, <\/strong>na qual determina-se sua capacidade como material para proteger contra o fogo, para permanecer coerente e fixado ao bet\u00e3o e para proporcionar dados sobre a distribui\u00e7\u00e3o das temperaturas em todo o elemento do bet\u00e3o protegido quando exposto \u00e0 curva padr\u00e3o de tempo\/temperatura.<\/p>\n
Com os dados de temperatura obtidos nos ensaios realizados, proporcionamos:<\/p>\n
– A rela\u00e7\u00e3o entre a temperatura do bet\u00e3o, o tempo e a espessura da prote\u00e7\u00e3o contra o fogo.<\/p>\n
– A espessura equivalente de bet\u00e3o.<\/p>\n
O bet\u00e3o utilizado pode ser leve, normal ou pesado e dos tipos de resist\u00eancia 20\/25 (LC\/C\/HC) a 50\/60 (LC\/C\/HC). O elemento pode conter barras de armadura de a\u00e7o.<\/p>\n
