Скачать или смотреть Wagners EFC® | Introduction to Geopolymer Concrete

Earth Friendly Concrete® (EFC®) is a traditional concrete that uses no ordinary Portland cement. Instead, EFC® uses a geopolymer binder system made from the chemical activation of two industrial waste by-products - blast furnace slag (waste from iron production) and fly ash (waste from coal-fired power generation). This alternative eco-friendly binder technology reduces the carbon emissions associated with normal Portland cement and also has a much lower embodied energy.

Importantly, the engineering and construction properties of this new environmental concrete are as good, and in some areas better, than normal concrete. In fact, EFC® has some significant performance advantages over normal Portland cement concrete, including improved durability, lower shrinkage, earlier strength gain, higher flexural tensile strength, and increased fire resistance.
