Ternary cements in Iceland

20 February 2013, Published under Cement News

Producing cement in Iceland is a unique experience. The scarcity or even absence of traditional raw materials on this volcanic island requires some inventive thinking. In addition, exposure to water, particularly seawater, heavy winds and cold weather makes special demands on the concrete and hence, the cement used in construction. This led to the development of ternary blended cement, using locally-available pozzolans. Dr Guðmundur Guðmundsson, former manager of the Iceland State Cement Wor...
