Apesar de sua falta de combustibilidade e baixa condutividade t\u00e9rmica, durante um inc\u00eandio o bet\u00e3o sofre com a forma\u00e7\u00e3o de press\u00f5es porosas e tens\u00f5es internas d\u00facteis que geram lascas explosivas. Isto tem como resultado a perda de sec\u00e7\u00f5es e a explos\u00e3o do a\u00e7o de refor\u00e7o a temperaturas extremamente elevadas.<\/p>\n
Adicionalmente, devido ao aquecimento o bet\u00e3o perde resist\u00eancia, principalmente em temperaturas superiores aos 300\u00b0C. Estes problemas podem ser enfrentados mediante a prote\u00e7\u00e3o passiva contra os inc\u00eandios dos elementos estruturais do bet\u00e3o.<\/p>\n
A prote\u00e7\u00e3o contra inc\u00eandios dos elementos estruturais do bet\u00e3o \u00e9 importante para prevenir a explos\u00e3o de estilha\u00e7os quando a um grau superior de temperatura o bet\u00e3o torna-se muito mais sens\u00edvel.<\/p>\n
Em termos gerais, a prote\u00e7\u00e3o passiva contra inc\u00eandios converte-se em um assunto priorit\u00e1rio em qualquer lugar que se apresente uma combina\u00e7\u00e3o que englobe as seguintes caracter\u00edsticas: preven\u00e7\u00e3o de explos\u00e3o de estilha\u00e7os; prote\u00e7\u00e3o do refor\u00e7o de a\u00e7o para que estes n\u00e3o excedam temperaturas cr\u00edticas; prote\u00e7\u00e3o para que o bet\u00e3o n\u00e3o exceda temperaturas excessivas.<\/p>\n
