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.

A dry grout composition including a calcium aluminosulfate based hydraulic cement, a mineral filler, a thixotropic agent, and a superplasticizer agent. Also, an anchoring capsule, containing the dry grout composition, for use in anchoring reinforcing member dowel, or anchor elements in a hole of a substrate, and a method of use.

A two-component mortar mass includes a resin component (A), which contains as curable constituent at least one radically curable resin, and a curing component (B) which contains a curing agent for the radically curable resin of the resin component (A), wherein the resin component (A) and/or the curing component (B) contain(s) as further constituent at least one inorganic additive. The inorganic additive contains a transition aluminum oxide having an average particle size d50 of at least 7.0 m and a pore diameter of 4.0 nm to 30.0 nm.

A reactive resin includes a vinyl ester resin based on renewable raw materials, in particular a dianhydrohexitol-based vinyl ester resin as the base resin. A reactive resin component containing this reactive resin is useful for chemical fastening.
