A sealant having a specific gravity in the range of from about 0.7 to about 1.6 for heavy oil and/or coal bed methane fields is disclosed. The sealant has a binder including an oxide or hydroxide of Al or of Fe and a phosphoric acid solution. The binder may have MgO or an oxide of Fe and/or an acid phosphate. The binder is present from about 20 to about 50% by weight of the sealant with a lightweight additive present in the range of from about 1 to about 10% by weight of said sealant, a filler, and water sufficient to provide chemically bound water present in the range of from about 9 to about 36% by weight of the sealant when set. A porous ceramic is also disclosed.
L'invention concerne un matériau d'étanchéité possédant une gravité spécifique comprise entre environ 0,7 et environ 1,6 pour champs de méthane de houille et de pétrole lourd. Ledit matériau d'étanchéité comprend un liant contenant un oxyde ou un hydroxyde de Al ou Fe et une solution d'acide phosphorique. Ce liant peut contenir MgO ou un oxyde de Fe et/ou un phosphate acide. Ledit liant représente entre environ 20 et environ 50 % en poids du matériau d'étanchéité qui renferme aussi un additif léger constituant environ 1 à environ 10 % en poids dudit matériau, une charge et de l'eau en quantité suffisante pour permettre à l'eau liée chimiquement qui représente entre environ 9 et environ 36 % en poids dudit matériau, après durcissement. Cette invention a aussi pour objet une céramique poreuse.
