The lightweight grout composition of the present invention comprises: 10-60 wt% of Portland cement, 1-10 wt% of silicon wafer waste sludge solid-liquid separation dry substance, 10-60 wt% of air cooling dry bottom ash, 0.1-10 wt% of calcium sulfoaluminate, magnesium sulfoaluminate, or calcium aluminate, 0.1-10 wt% of anhydrous gypsum, gypsum hemihydrate, or gypsum dihydrate, 0.01-3 wt% of superplasticizer, 0.001-1 wt% of thickener, and 0.01-1 wt% of anti-foaming agent. The lightweight grout composition of the present invention: reduces fractures caused by compressive, bending, and tensile strengths thereof at early ages, especially by an expansion characteristic thereof at early ages by being mixed with the silicon wafer waste sludge solid-liquid separation dry substance; has improved acid proof and chloride invasion resistance by using dry bottom ash having pozzolanic reaction properties ...

The present invention relates to a zeolite complex catalyst, and to a preparation method thereof. More particularly, the zeolite complex catalyst has high heat resistance, excellent oxidation resistance, and excellent chemical resistance. Also, the zeolite complex catalyst has remarkably excellent persistency of catalytic activity while having excellent catalytic activity, thereby having an extended duty cycle. The preparation method of the zeolite complex catalyst comprises the following steps of: (1) forming a silica (SiO2) layer on the surface of a silicon-based support; and (2) growing zeolite particles on the silica layer. COPYRIGHT KIPO 2016 (S1) Step of forming a silica layer on a surface of a silicon-based support (S2) Step of growing zeolite particles on the silica layer ...
