Description

本発明は、硫化水素発生を抑制できる石膏組成物、石膏系建材及び石膏系固化材に関し、さらに詳しくは、石膏の硫黄成分によって硫化水素が発生し難いように構成されている硫化水素発生を抑制できる石膏組成物、これを用いた石膏系建材及び石膏系固化材に関する。 The present invention relates to a gypsum composition, a gypsum-based building material, and a gypsum-based solidifying material capable of suppressing hydrogen sulfide generation, and more specifically, suppressing hydrogen sulfide generation that is configured so that hydrogen sulfide is not easily generated by the sulfur component of gypsum. The present invention relates to a gypsum composition , a gypsum-based building material and a gypsum-based solidifying material using the gypsum composition.

さらに、本発明の別の実施形態としては、上記いずれかの石膏組成物を原料としてなることを特徴とする石膏系建材、或いは、上記いずれかの石膏組成物を有することを特徴とする建設残土や汚泥や泥土の土壌処理用の石膏系固化材が挙げられる。
Furthermore, as another embodiment of the present invention, a gypsum-based building material characterized by using any one of the gypsum compositions described above as a raw material , or a construction residual soil characterized by comprising any gypsum composition described above. And gypsum-based solidifying materials for soil treatment of sludge and mud .
