Abstract

A multi-component mortar system contains a curable aqueous-phase aluminous cement component A and an initiator component B in aqueous-phase for initiating the curing process. Component A further contains at least one plasticizer, water, and at least one blocking agent selected from phosphoric acid, metaphosphoric acid, phosphorous acid, and phosphonic acids. Component B contains an initiator, at least one retarder, at least one mineral filler, and water. A multi-component system is useful, which is ready-for-use, for chemical fastening of anchoring means, preferably of metal elements, in mineral surfaces, such as structures made of brickwork, concrete, pervious concrete or natural stone as well as its use for chemical fastening of anchoring means.
