Expanding stabilizing cement slurry is manufactured based on Portland cements, active polydisperse siliceous additives, and expanding components. If necessary, water loss properties, rheological parameters, reinforcing properties, etc., can be modified.
ECS
ECS
Chemical description
Ecs (extendcem c 50) represents a multicomponent mixture of mainly inorganic materials.
Physical properties

Solubility in water: partial
Properties of cement stone
Compressive strength at 50°C: not less than 20 MPa
Density: 1.7 g/cm³ - 2.0 g/cm³
Thickening time: within 10 - 16 hours
Expansion: 1.5% - 5%
Density: 1.7 g/cm³ - 2.0 g/cm³
Thickening time: within 10 - 16 hours
Expansion: 1.5% - 5%
Advantages
- Improvement of adhesive properties of the cement slurry, enhancing the quality of bonding between the casing and the formation;
- Designed for effective isolation of productive layers in intervals ranging from 15 to 50°C and prevention of cross-flows between layers;
- Exhibits expansion effect – ensures maximum filling of the annular space.
Usage limitations
Operating temperature range from 16°C to 100°C
Packaging and storage conditions
The Expanding Cement System (ECS) is packed in soft containers (FIBC) weighing up to 1 ton, equipped with a triple polyethylene liner. The product is recommended to be stored in a dry place on pallets away from moisture, open flames, and heating devices. After the FIBC has been opened, it is necessary to ensure the packaging is sealed tightly to prevent product spoilage. The shelf life of the product is not less than 12 months.
APPLICATION
Used for cementing technical and operational columns
In intervals of moderate temperatures with the technological necessity of expanding the cement stone.
Stimulates the crystalline growth of cement stone.
During its formation, it stimulates the crystalline growth of cement stone, eliminating shrinkage and allowing maximum filling of the annular space. This effect has a positive impact on both insulation quality and CBL results.
It has increased sedimentation stability
And reduced water loss, which positively affects the cementing results in the interval.
