细碳酸钙在基于矾土水泥的无机砂浆体系中的用途以增加载荷值
摘要：
本发明涉及平均颗粒尺寸在0.5-3μm范围内、优选在1-3μm范围内的碳酸钙在无机砂浆体系中的用途，用于锚定物和后安装加强筋在矿物基材中的化学紧固，其包含可固化的矾土水泥组分A和用于引发固化过程的引发剂组分B，所述组分A还包含至少一种封闭剂和至少一种增塑剂和水，所述封闭剂选自磷酸、偏磷酸、亚磷酸和膦酸，并且所述组分B包含引发剂、至少一种延缓剂、至少一种矿物填料和水。此外，本发明涉及平均颗粒尺寸在0.5-3μm范围内、优选在1-3μm范围内的碳酸钙在无机砂浆中的用途，以便增加载荷值，并且涉及锚定物和后安装加强筋，优选为金属锚定物和后安装加强筋，在矿物基材中的化学紧固的方法，所述矿物基材是例如由砖块、混凝土、透水混凝土或天然石材制成的结构。
摘要（英）：

The present invention pertains to a use of calcium carbonate having an average particle size in the range of from 0.5 to 3 microns, preferably of from 1 to 3 microns, in an inorganic mortar system fora chemical fastening of anchors and post-installed reinforcing bars in mineral substrates, comprising a curable aluminous cement component A and an initiator component B for initiating the curing process, component A further comprising at least one blocking agent selected from the group consisting of phosphoric acid, metaphosphoric acid, phosphorous acid and phosphonic acids and at least one plasticizer and water, and component B comprising an initiator, at least one retarder, at least one mineral filler and water. Moreover, the present invention pertains to a use of calcium carbonate havingan average particle size in the range of from 0.5 to 3 microns, preferably of from 1 to 3 microns, in an inorganic mortar to increase load values as well as to a method for a chemical fastening of anchors and post-installed reinforcing bars, preferably of metal anchors and post-installed reinforcing bars, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete or natural stone.
