    Product Description

    G204 can stabilize and strengthen low density cement slurry through bridging and changing concentration of ion in cement slurry. 

    Characteristics

    Mainly composed of inorganic early-strength materials.
    No-toxic, odorless.
    Normal dosage: 1.0%~5.0% (BWOC).
    Suitable temperature: 30℃~90℃(BHCT).
    Can decrease free fluid and volume contraction in low density cement slurry, stabilize and enhance the strength.
    Obvious effects of early strength. The strength of cement is more than 6MPa after 24 hours.
    Can be used in ultra low density cement slurry systems (1.65±0.01g/cm3).
    Suitable for low density cement slurry of fly ash, normal oil well cement, and low density cement slurry of glass micro-spheres. 
    It can also play a better early strength effect in conventional specific gravity cement slurry.
    Mixed without water.

    Technical Specification

    Test conditions: G class cement:floating beads: micro-spheres=100:10:5, W/C (water to cement): 0.70, Dosage of G204:2.0% (BWOC), Water quality: distilled water.
