<p>The invention refers to a binding agent for sprayed concrete where the binding agent is a certain mineral hydraulic compound with low sulphate content, preferentially portland cement, portland composite cement, slag cement, ferrous portland cement or alumina cement and containing usual, in a given case additional components and agents. The components of the binding agent are balanced in such a way as to achieve a short duration of hydraulic reactions, where the binding agent particles have, at least to a partial extent, their envelope made of a combination of a hydrophobic and an accelerating agent without alkalis.</p> |
