Two-component mortar system based on aluminous cement and use thereof

A process for fastening a construction element within a mineral substrate, the process comprising:

• arranging separately produced component A and component B of a multi-component mortar system comprising:
• a curable aqueous-phase aluminous cement component A, and
• an initiator component B in aqueous-phase for initiating a curing process;
• wherein component A comprises at least one blocking agent and water, and component B comprises an initiator, at least one mineral filler, and water, in separate containers,
• ejecting component A and component B by a mechanical device,
• guiding component A and component B through a mixing device, to obtain a mixture of component A and component B,
• injecting the mixture of component A and component B into a borehole,
• inserting the construction element into the borehole, and
• leaving the mixture of component A and component B to set and harden,
• wherein said multi-component mortar system has an initial set-time of at least 10 min.
