More Information
Summary:The present invention relates to a shotcrete binder composition to reduce rebound and dust generation and, more specifically, to a shotcrete binder composition to reduce rebound and dust generation, which generally uses a shotcrete binder combining Portland cement, a particle size classifying fine particle cement, a fine powder of blast furnace slag, a highly fine powder of limestone, and an alkali stimulating agent to improve viscosity and yield stress to reduce rebound and dust generation of shotcrete; and improve the economic feasibility of shotcrete and improve a working condition by the same.
