Abstract

A dry mix, for producing a cement suspension for filling and/or injecting pore spaces and cavities in loose rock or cavities and/or cracks in rock or in concrete components, is in the form of a ready mix containing (a) sulphate additive-free finely ground clinker and/or smelter sand powder; (b) additives; and (c) an ettringite-forming swelling component which produces swelling during strength development of the fine cement-binder mixture while the matrix is still soft after the filling and/or injection operation. The entire homogeneous dry mix has a continuous graduated particle distribution with sieve pass values of d95 = ≤ 24 (preferably ≤ 16) microns and d50 = ≤ 7 (preferably ≤ 5) microns, the d50/d95 ratio preferably being 0.33 plus or minus 0.04. Preferably, the mix contains a naphthalene sulphonate-formaldehyde condensate as plasticiser. Also claimed are: (a) preparation of the above dry mix, in which all the components have the above defined fineness and particle distribution and are stored separately in storage silos, certain components being dosed from the corresponding silos for delivery to a mixer and the components being homogenised and mixed in the mixer to form the ready mix; and (b) apparatus for carrying out the above process, in which a storage silo (7-12) is provided for each component and is combined with a dosing device, the silos being followed by a mixer (14).
