O chert, tamb\u00e9m conhecido como s\u00edlex, \u00e9 uma rocha sedimentar rica em s\u00edlica. O chert \u00e9 muito duro e as suas fracturas conchoidais podem deixar arestas afiadas que n\u00e3o se apagam facilmente. Por esta raz\u00e3o, foi um dos primeiros materiais utilizados em ferramentas e armas.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Nalgumas \u00e1reas, o chert \u00e9 omnipresente como cascalho de ribeira e pedra de campo e \u00e9 atualmente utilizado como material de constru\u00e7\u00e3o e revestimento de estradas. Parte da popularidade do chert no revestimento de estradas ou na constru\u00e7\u00e3o de entradas \u00e9 que a chuva tende a firmar e compactar o chert, enquanto outros materiais de enchimento ficam frequentemente lamacentos quando molhados.<\/p>\n

Os cherts est\u00e3o sujeitos a problemas quando utilizados como agregados para bet\u00e3o. O chert profundamente intemperizado desenvolve sali\u00eancias na superf\u00edcie quando utilizado em bet\u00e3o sujeito a congelamento e descongelamento devido \u00e0 elevada porosidade do chert intemperizado. A outra preocupa\u00e7\u00e3o \u00e9 o facto de certos cherts sofrerem uma rea\u00e7\u00e3o \u00e1lcali-s\u00edlica com cimento altamente alcalino. Esta rea\u00e7\u00e3o leva \u00e0 fissura\u00e7\u00e3o e expans\u00e3o do bet\u00e3o e, em \u00faltima an\u00e1lise, \u00e0 falha do material.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
