ENVIRONMENTAL LOW CARBON DIOXIDE BINDER COMPRISING METAL SALT REACTIVE COMPOUNDS AND CONCRETE COMPOSITION USING THE SAME

摘要

PURPOSE: An environment-friendly low carbon binder which is grafted with metallic salt-based reactive compound and a concrete composition using thereof are provided to reduce hydration heat followed by use of reaction accelerator and to improve mobility and durability. CONSTITUTION: An environment-friendly low carbon binder which is grafted with metallic salt-based reactive compound comprises 1-5 parts by weight of reactive compound and 1-3 parts by weight of acetate based compound based on 100.0 parts by weight of binder. The binder comprises 10-40 parts by weight of cement and 60-90 weight% of blending material. The blending material is one or more which are selected from fly ash and blast furnace slag. The reactive compound is one or more which are selected from magnesium salt based compound, lithium salt based compound, and sodium salt based compound. The cement is a first OPC(ordinary Portland cement). The magnesium salt based compound is MgCl2·6H2O. The lithium salt based compound is LiNO3·3H2O. The sodium salt based compound is Na2S2O3·5H2O. The acetate based compound is CH3COONa·3H2O.
