SECONDARY CONSTITUENTS IN PRODUCTION OF CEMENTS

SUBSTITUT-RAAMATERIALER I CEMENTPRODUKTIONEN-TEKNISKE ASPEKTER

This paper surveys the pros and cons of producing cements based on portland clinker and substitute raw materials. The trend from product to performance standards, dwindling resources and the environmental advantages of disposing in this way of waste materials or polluting by-products are mentioned as incentives. The disadvantages of the use of substitute raw materials are examined. Although fuel for clinker burning is saved, additional energy is needed for drying, transporting and grinding the new materials. Their economic attractions must be considered in relation to the increased costs of checking raw materials and cement and, in particular, the extra capital and operating costs of a distribution system complicated by the marketing of an additional type of cement. The paper also examines some properties of concretes made with the mixed cements. /TRRL/
