Durability of composite cements with calcined clay

13 December 2018, Published under Cement News

Composite cements are clinker efficient and play an important role in reducing CO 2 emissions from cement manufacturing. To assure their correct application in concrete, their performance in concrete has to be demonstrated, especially with regard to durability under different concrete exposure conditions. As part of a long-term research programme, such cements made of different calcined clays were used in conventional concrete mixtures and tested for their resistance to carbonation, chlorid...
