O bet\u00e3o celular autoclavado como material de constru\u00e7\u00e3o tem sido produzido industrialmente desde o in\u00edcio do s\u00e9culo XX. Na sec\u00e7\u00e3o abaixo l\u00ea sobre a hist\u00f3ria relativamente curta deste material de constru\u00e7\u00e3o de longa dura\u00e7\u00e3o. A vers\u00e3o alargada do artigo “Hist\u00f3ria do bet\u00e3o celular autoclavado”<\/a> pode ser encontrada num artigo especializado publicado na nossa sec\u00e7\u00e3o de download.<\/p>\n

Os primeiros dias<\/h3>\n

Os primeiros desenvolvimentos na hist\u00f3ria do bet\u00e3o aerado autoclavado s\u00e3o baseados numa s\u00e9rie de patentes de processos. Em 1880, um investigador alem\u00e3o Michaelis recebeu uma patente sobre os seus processos de cura a vapor. Hoffman checo testou e patenteou com sucesso em 1889 o m\u00e9todo de “arejamento” do bet\u00e3o por di\u00f3xido de carbono. Os americanos Aylsworth e Dyer utilizaram p\u00f3 de alum\u00ednio e hidr\u00f3xido de c\u00e1lcio para obter uma mistura ciment\u00edcia porosa, para a qual tamb\u00e9m receberam uma patente em 1914. O sueco Axel Eriksson deu um passo s\u00e9rio em direc\u00e7\u00e3o ao desenvolvimento da AAC moderna quando em 1920 patenteou os m\u00e9todos de fazer uma mistura aerada de calc\u00e1rio e ard\u00f3sia mo\u00edda (uma chamada “f\u00f3rmula da cal”).<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
