    Abstract: A composition for use as an additive for enhancing the strength of a cementitious composition, the composition comprising an alkanolamine comprising ethanoldiisopropanolamine (EDIPA) and optionally at least one selected from the group consisting of triisopropanolamine (TIPA), diethanolisopropanolamine (DEIPA), triethanol amine (TEA), and tetrakis-(2-hydroxyethyl)ethylenediamine (THEED); at least one set retarder selected from the group consisting of a gluconate salt, sucrose, corn syrup, and molasses; and at least one set accelerator selected from the group consisting of a thiocyanate salt, sodium chloride, and calcium chloride, wherein the alkanolamine and the set accelerator are present at a mass ratio of from 0.2 to 4.0 and the set accelerator and the set retarder are present at a mass ratio of from 1 to 10. The additive enhances the short term and long-term strength of cement when hydrated.
