描述:

Special ultralight sedimentation-resistant cementing material BauCem UL-50 for well cementing, which has high contact strength of cement stone with the wall of the well and casing, with a variable density of mortar in the range of 900–1350 kg / m³. It was produced on the basis of high-quality grouting Portland cement, unique in chemical composition of specially modified, mechanically and thermally treated bentonite clay of Russian deposits and special additives that regulate grouting and technical properties.

概观:

Benefits

the ability to control the density of the solution during application by simple methods (increase the time and speed of mixing, the use of hydroactivators, hydraulic funnels);
the use of the material does not require the introduction of special additives in the preparation of the solution
(in dry form at the well it simply mixes with water);
possesses:
- good colmatizing ability;
- optimal thixotropic properties;
- adjustable terms of thickening and setting;
- normalized expansion;
economical: the solution yield is up to 1.5 m³ / t;
allows cementing columns in various mining and geological conditions
without the use of MSCs (step cementing couplings);
not demanding mixing fluid.

Cooking

The mixing and pumping of the BauCem UL-50 grouting mortar can be carried out in any way (through a chunk, hydraulic funnel, etc.), according to the Customer's guidance document, using a water-mixing ratio.
To obtain the optimal rheological properties of the cement slurry and strength characteristics of cement stone, it is necessary to use averaging tanks.

Recommendations

Temperature range of application of the BauCem UL-50 grouting material from 20 to 50 ° C.
At negative and low positive ambient temperatures (from +5 to -30 ° C), it is advisable to use heating fluid mixing.
When using the “on-pass” method (“in years”), the use of a hydroactivator is recommended
(stream to stream or stream to wall).
