摘要：

To prove the applicability of cement with calcined clays as main constituent in concrete the performance of such composite cements, especially with regard to durability, has to be demonstrated. Composite cements with different calcined clays were used in conventional concrete mixtures and tested for their resistance to carbonation, chloride migration, frost and frost-deicing salts. Attention had to be paid to the workability of the concretes which could be affected strongly by the increases in the water demand of cements with calcined clays. Adjustments with superplasticisers could become necessary. The results of the durability tests showed that the performance of such binder systems is comparable to cements with other substitution material like limestone, slag or fly ash.
