    摘要： The present invention relates to a carbonic acid adduct (CAA) comprising carbonic acid, at least one amine, and optionally at least one salt, said adduct being producible by a method comprising the following steps: a) providing a solution (A) comprising dissolved CO2; optionally b) dissolving a base (BA) not corresponding to the amine (AM) in the solution (A) so as to obtain the solution (A1); c) dissolving the at least one amine (AM) in the solution (A) or (A1) so as to obtain the solution (B); d) freezing the solution obtained after completion of step c); and e) storing the solution frozen in step d) at −100 to 0° C. for no longer than 4 days. The content of CO2 in the solution that is subjected to step c) is at least 6 g/l. The invention also relates to a method for producing the carbonic acid adduct (CAA), a pharmaceutical preparation (PP) comprising the carbonic acid adduct (CAA), and methods for the production thereof and use of the carbonic acid adduct (CAA) or the pharmaceutical preparation (PP) in therapy for a range of indications.

    摘要： 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.

    摘要： A hydratable cement composition which will bond to both asphalt and cementitious substrates is supplied for the repair of various surfaces. The composition comprises of a combination of Portland cement, calcium sulfoaluminate cement or calcium aluminosilicate, and an alkali metal salt activated pozzolonic powder, wherein the Portland cement content of the hydratable portion of the composition is greater than 20%. The composition is free from latex bonding agents and calcium aluminate. The composition is mixed with water to form a typical cement, mortar, or concrete consistency, placed and allowed to cure. The result is a self-adhering patch to damaged surfaces. The hydratable cement composition may also be used to fabricate items of original construction by casting into molds or forms.

    摘要： Embodiments provide a mortar slurry and a method for preparing a hardened mortar. The method includes the steps of: mixing an aramide capsule, a cement, a silica, and a water to form a mortar slurry; and allowing the mortar slurry to set to form the hardened mortar, where the aramide capsule is embedded in the hardened mortar. A continuous solvent and a surfactant are mixed to produce a continuous phase. A dispersed solvent and a dispersed monomer are mixed to produce a dispersed phase. The continuous solvent and a crosslinker are mixed to produce a crosslinker solution. The continuous phase and the dispersed phase are mixed to form a mixture having an emulsion such that the dispersed phase is dispersed as droplets in the continuous phase, where an interface defines the droplets of the dispersed phase dispersed in the continuous phase. The crosslinker solution is added to the mixture such that the crosslinker reacts with the dispersed monomer. An aramide polymer forms on the interface of the droplets, forming the aramide capsule. The aramide capsule is settled and separated from the mixture, and is dried to form a free flowing powder.
