| Descripción: | This article collects and identifies the addition of certain mineral additives most frequently used in the construction industry as modifiers of concrete during its fresh and hardened state, most of which are used as a partial replacement for cement. Currently researchers seek to optimize the properties of the design of mixtures depending on the use for which they are conceived, as well as that it is economically feasible and respectful with the environment. 50 articles indexed between 2010 and 2021 distributed in the following databases were reviewed: 37 articles from Scopus, 10 articles from ScienceDirect, 2 articles from Springer and 1 article from SciELO. The additives under study are granulated blast furnace slag (EAHG), fly ash (CV), silica fume (HS), rice husk ash (CCA). Most of them present a considerable improvement in their mechanical characteristics of traction, resistance to compression and modulus of elasticity. The addition of CV improves the mix of the design during its fresh state, the CCA during its hardened state and the best resistances for the HS; However, the EAHG turns out to meet almost all expectations in a higher percentage and likewise, together with the CCA, they are potentially competitive |
