The purpose of this paper is to study some mix design on different mortar mixtures whose results aim at obtaining high mechanical strengths, especially for flexural strength, with low water absorption, to prevent material degradation due to the action of various environmental factors and also to ensure their durability. From the category of cement additions widely used in the current practice due to their pozzolanic and hydraulic activity in latent condition, we refer to silica fume (SF) which is a mineral additio...

This paper focuses on a study regarding the use of waste in constructions: such as blast furnace slag from ironworks, as a by-product of the iron oxide reduction reactions by carbon monoxide resulting from coke burning. The slag is used in cement-based mortar mixtures under two forms: as granulated and ground slag powder under 63 ?m and non-granulated slag as an 0/4 mm aggregate resulting from solid slag, processed in crushing equipment and then sorted according to the standards on mortar and concrete aggregates. ...
