PURPOSE : A reinforced soil block composition using carbon-reducing inorganic binder is provided to satisfy compressive strength and absorption rate of group standard capability rules of the reinforced earth block.CONSTITUTION : A reinforced soil block composition using carbon-reducing inorganic binder comprises 200-300 parts by weight of aggregate with less than 5mm, 10-100 parts by weight of building stone micro powder, 30-200 parts by weight of aggregate, and 10-40 parts by weight of mixing water based on 100 parts by weight of carbon reducing inorganic binder. The carbon reducing inorganic binder comprises 40-80 wt% of alkali activated slag based binder, 5-20 wt% of industrial by-product activation stimulant, 10-40 wt% of sulfate group activation stimulant, and 1-5 wt% of absorption rate reducer. The alkali activated slag based binder is composed of one or more of aluminosilicate based industrial byproduct and ordinary Portland cement. The industrial by-product activation stimulant is composed of more than one or more of paper mill sludge ash, high calcium fly ash and red mud dry powder.COPYRIGHT KIPO 2013
