Abstract

The development of construction additives based mainly on by-products or wastes of the Cuban industry has been one of the research lines in the Materials and Corrosion Engineering Group in the Faculty of Chemical Engineering. Technological University of Havana. The proposed objective is showing an overview of the main results obtained in the study of these substances and the enormous perspectives offered by the Cuban industry in the development and production of additives for construction. The by-products of the sugar industry and other industries that use these by-products, together with some waste, constitute a source for the production of different substances to be used in the industry in general, including the construction industry. The work shows the additives developed for concretes, mortars and gypsum terminations. Between the first two are, water reducers, plasticizers, retarders and anti-corrosion agents. The development, production and use of these additives would allow the substitution of imports, the use of by-products and eliminate polluting residues from the environment of the national industry.
