Products

Tekbar M Cementitious Mix is a high-performance, fast-setting,
one-component cement-mineral product designed for the construction of
structures in the underground conditions of coal mines and mining
operations.

Initial setting time at 10 °C

4.5 ± 2.5 min

Compressive strength (28 days)

>7.5 MPa

Cement mix consumption

840 ± 10 kg/m³

Applications

► Construction of isolation, explosion-resistant, and water-tight
stoppings
► Construction of protective barriers for roadways adjacent to longwall
faces
► Filling voids and roof cavities behind mine support systems and sealing
boreholes
► Sealing annular spaces during the casing of degasification and
preventive boreholes
► Enhancement of existing isolation structures (extensions to previously
constructed stoppings and protective linings in crossings and crosscuts)

Component Description

Tekbar M is a one-component cement-mineral product.

Key Advantages

► Rapid strength development
► Short setting and flow-loss time
► High compressive and tensile strength
► Higher load-bearing capacity compared to conventional sand-cement
mixtures
► The cementitious mix is non-combustible, non-explosive, and
non-flammable
► Ready-to-use packaged product that minimizes human error during
preparation and reduces losses during handling and transportation

Operating Principle

After mixing with water, the Tekbar M cementitious mix forms a cement
paste (mortar), which is placed into the formwork using a specialized
MONO WT 820 pumping unit.

Packaging

Tekbar M is supplied in 20 kg polypropylene bags with polyethylene liners,
packed in 1,000 kg big bags (FIBCs).

Storage

Shelf Life: At least 9 months when stored in dry and cool conditions.

Storage: Store in a location protected from direct sunlight.

Equipment

Using a MONO WT 820 pumping unit.
