Supply of the products necessary for the formulation of the tamping mortars
The high pressures exerted by the depth imposed a preliminary laboratory study in our laboratory. The two-component tamping mortar The two-component tamping mortar is composed of the following MAPEI products: - MAPEQUICK CBS 3, a gas pedal to activate the setting process of the cement the setting process of the cement present in the mortars when added to the when added to the mixture during the injection phase. MAPEQUICK CBS 3 should also to develop early age strengths. - MAPEQUICK CBS 1, a retarder with a cement-thinning effect for mortar and grout. It is added to mortars and grouts mortars and grouts requiring high workability maintenance (long transport times or transport or pumping distances). MAPEQUICK CBS 1 improves grout stability and also its viscosity. - MAPEBENT API 2, an API 2 grade sodium bentonite suitable for for all types of civil engineering applications. |
