摘要

Mortar of very high performance. This mortar is obtained by mixing with water a mixture which comprises a Portland cement, a vitreous microsilica obtained as byproduct in the zirconium industry, a superplasticising agent and/or a wetting agent, a quarry sand, optionally other adjuvants, in the proportions shown. The invention makes it possible in particular to obtain mortars which have a crushing strength of the order of 250 MPa and to prepare concrete of very high performance.
