Chemical description
LCS (LIGHTWEIGHT CEMENT SYSTEM) REPRESENTS A MULTICOMPONENT MIXTURE OF MATERIALS, PREDOMINANTLY OF INORGANIC ORIGIN
Physical properties
Appearance: powder, ranging from gray to dark gray color
Solubility in water: partial
Solubility in water: partial
Properties of cement stone
Density of cement slurry — 1.0 g/cm³ – 1.7 g/cm³
Compressive strength after 24 hours at 60°C — not less than 6.9 MPa
Thickening time at 60°C — adjustable
Compressive strength after 24 hours at 60°C — not less than 6.9 MPa
Thickening time at 60°C — adjustable
Advantages
- The cement stone has increased early and final strength.
- The cement stone has enhanced adhesive properties compared to standard lightweight systems.
- Thanks to improved rheological parameters, the cement slurry facilitates its injection into the well with small clearances without a significant pressure increase.
Usage limitations
Operating temperature range from 20°C to 130°C.
Packaging and storage conditions
Lightweight cement system (LCS) 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 opening the FIBC, it is necessary to ensure the packaging's tightness to prevent product spoilage. The product has a shelf life of at least 12 months.
APPLICATION
In conditions of MKP leakage risk
for cementing technical and operational columns in intervals with increased MKP leakage risks or when it is necessary to shorten the time of cement setting.
Differs in strength.
It has increased early and final strength of the cement stone.
It has increased sedimentation stability
and reduced water loss, which has a positive impact on cementing interval results.
