Cured composition and cured article

本发明涉及一种硬化组合物，特点在于，含有(A)一种矿渣组合物，含有0～37wt％的CaO、23～90wt％的SiO#-[2]、和0～40wt％的Al#-[2]O#-[3]和0.1～50wt％的一种或多种选自由氧化铁、碱性组分、含磷组分、二氧化钛、氧化锰、和氧化镁组成的组中的化合物，和/或0.1～10wt％的卤素；和(B)一种碱性激活剂。本发明还涉及通过把所说的硬化组合物与水混合得到的硬化产物。所说的硬化产物适用于各种混凝土材料，所以，可以有效地利用垃圾焚烧后的灰分、污水污泥等，并作为资源再循环。 The present invention is directed to a hardening composition characterized by comprising (A) a slag composition containing 0 to 37 wt.% of CaO, 23 to 90 wt.% of SiO2, and 0 to 40 wt.% of Al2O3 and 0.1 to 50 wt.% of one or more compounds selected from the group consisting of iron oxide, alkali components, phosphorous components, titanium dioxide, manganese oxide, and magnesium oxide, and/or 0.1 to 10 wt.% of a halogen; and (B) an alkaline activator. The invention is also directed to a hardened product obtained by mixing the hardening composition with water. The properties of the hardened product are suitable for use as various concrete materials, and therefore, refuse-incinerated ashes sewage sludge, etc. are effectively utilized and recycled as a resource.
