High performance and durability of recycled silica fume mortars

Abstract

The purpose of this article is to develop a special mortar, realized using cement, silica fume, sand, water and super plasticizer. The proposed silica fume mortar should have high mechanical properties such as compressive and tensile strength, but also good workability. The samples were tested at 28 days; in function of compressive and bending tensile strengths the special mortars researched can be framed into repair mortars. By recycling of silica fume we can help to protect the environment.
