Abrégé

Disclosed is a mixture comprising two components to be mixed together to form a settable cementitious composition wherein a first component comprises: (a) Portland cement; (b) calcium sulphate; and (c) water in a weight ratio of water to Portland cement and calcium sulphate solids of from 0.5:1 to 5:1; and a second component comprises: (d) a water soluble silicate; and (e) water, in a weight ratio of water to silicate solids of from 1.5:1 to 25:1; which cementitious composition has a high early strength. The mixture is suitable to be used in an inflatable support for use in mines, since it hardens slowly and remains its plasticity in order to deform under load.

A method, apparatus and inner pipe for renovating a pipe (1) or conduit makes it possible to deliver a filling material/multi-component resin (15) in a targeted manner to the place of use. This is provided by shaping the inner pipe (5) into the form of a trough before introducing it into the pipe section (3) to be renovated. The quantity of filling material/multi- component resin (15) is preferably selected while charging the trough (16), preferably via the pipe-charging connecting piece (26), so that the required quantity is provided at the point of use in order to fill the intervening space (14) and any cavities (11, 12). This precisely targeted filling process is provided by carrying out the reverse deformation of the trough-shaped inner pipe (5).

According to the invention, a drill rod comprising an inner channel is drilled
into the rock. A free-flowing, self-hardening mass is pressed through the
inner channel of the drill rod, filling the drilled hole, so that it hardens
with the drill rod remaining in the drilled hole. The hardening mass is a
mixture of a hardenable plastic and a hardening plastic. Said plastics are
supplied to the inner channel of the drill rod over a pre-determined transport
time F which corresponds to the hardening time. The hardening time is defined
by the selection of the plastics and the mixing ratio thereof such that the
transport time essentially corresponds to the hardening time and leads
essentially to the flow path of the hardened mixture being completely filled
between the mixing point and the output of the drilled hole.
