In publication since 1974, the 1996 edition of the annual review of research on Portland cement and related materials focuses cement manufacture and nomenclature, chemistry and structure of hydration products, properties of fresh and hardened paste, curing of Portland cement and concrete, chemical admixtures, durability of cements, calcium phosphate cements, and the art and science of high-performance concrete (a special section). Papers, reports, and patents during 1996 reflect interests in alternative raw materials and technologies, as well as improving environmental conditions around cement manufacturing facilities.
