    Product Description

    G209L can change ion concentration in cement hydrate to accelerate the acting of C3S、C3A and forming of calcium aluminous stone. So it can densify the structure and enhance early strength.

    Characteristics

    G209L main consists of inorganic compound. 
    Normal dosage: 1.5%~4.0% (BWOC).
    Suitable temperature: 28℃~110℃(BHCT).
    Suitable for low and conditional density cement slurry .
    Suitable for low density cement slurry of fly ash ,normal oil well cement and low density cement slurry of glass micro-spheres. 
    Preferred to mix with water.

    Technical Specification

    The ingredient of cement slurry in the table is: JiaHua G class cement, W/C0.44,
    G209L: 2.5%(BWOC), Water quality: distilled water.
