Study of high early strength of mortar for repairing contruction works

Abstract

    The high strength mortar with no shrinkage propertie is increasingly used in the construction sector. Especially, this type of motar is common for repairing works such as transportation works and an indispensable feature is high early strength developpement. This article studies the mix design of non-shrinkage mortar with early strength development used to repair construction works in general and transportation works in particular. The material used for design this motar is local material. The mix design of mortar have to ensure the mechanical properties: mobility; compression strength; no shrinkage and especially early development, after 3 hours the compressive strength is 30 MPa
