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.

Abstract: Amorphous calcium carbonate is included in a fire-resistant inorganic mortar system for a fire-resistant chemical fastening of anchors and post-installed reinforcing bars in mineral substrates. The system includes a curable aluminous cement component A and an initiator component B for initiating the curing process. The component A includes at least one blocking agent selected from the group of phosphoric acid, metaphosphoric acid, phosphorous acid and phosphoric acids, at least one plasticizer and water. The component B includes an initiator, at least one retarder, at least one mineral filler and water. Moreover, amorphous calcium carbonate in a fire-resistant inorganic mortar increases load values. Also, a method is used for a fire-resistant chemical fastening of anchors and post-installed reinforcing bars in mineral substrates, such as structures made of brickwork, concrete, pervious concrete or natural stone.

Abstract: A method is useful for producing a urethane(meth)acrylate resin composition. The method improves storage stability and reduces the reactivity drift of the composition compared to compositions made by other means from the same starting materials. In particular, it reduces the degradation of TEMPOL in mixtures with branched urethane resins.

Abstract: A two-component mortar mass comprises a resin component (A), which contains at least one radically curable resin as a curable constituent, and a curing component (B), which contains a curing agent for the radically curable resin of the resin component (A). The radically curable resin can be obtained by reaction of an at least difunctional isocyanate with a hydroxy-functional silane and a hydroxy-functional, ethylenically unsaturated compound. The hydroxy-functional silane is the reaction product of a cyclic compound from the group of cyclic carbonates, lactones, and carbamates with a silane compound selected from the group of amino-functional, hydroxy-functional or mercapto-functional silanes.
