  • Fire-resistant two-component mortar system based on aluminous cement for a fire-resistant chemical fastening of anchors and post-installed reinforcing bars and use thereof
    Patent number: 11858866
    Abstract: A fire-resistant two-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 blocking agent selected from phosphoric acid, metaphosphoric acid, phosphorous acid and phosphonic acids, at least one plasticizer, and water. Component B contains an initiator, at least one retarder, at least one mineral filler, and water. A fire-resistant two-component system, which is ready-for-use, can be used for a fire-resistant chemical fastening of anchors and post-installed reinforcing bars in mineral surfaces, such as structures made of brickwork, concrete, pervious concrete or natural stone.
