　　There is an increasing decline in the availability of traditional pozzolans due not only to their reduced exploitation and limitations on quarrying, but also to the downward trend in the establishment of new sites,mainly to minimize the environmental impact on the landscape.Also, environmental policies are focused on the decrease or elimination of dumps, prioritizing the recycling of waste products and industrial residue as raw materials in cement manufacture.All of these reasons mean that the use of alternative pozzolans involves the search for by-products and waste that may present pozzolanic activity.The principal aim of this work is the recovery of one of these by-products (ceramic sludge) from the enamelling and milling stages in the ceramic industry as pozzolanic components in cement.
