    State-of-the-art polycarboxylic superfluidifying admixtures with SBA (Sand Blocker Admixtures) technology for summer climates.

    DRACRIL SAND BLOCKER R is a latest-generation superfluidifying admixture specifically formulated for the production of concretes in hot climates and made using ‘difficult sands’ (containing clay or a high content of fine parts). DRACRIL SAND BLOCKER R contains new-generation synthesis polymers with SBA (Sand Blocker Admixtures) technology that enables the production of very high-performance concretes characterised by a very low water-cement ratio and excellent rheological properties even in the presence of complex sands and summer climates.


    • 20 kg can.
    • 200 kg drum.
    • 1000 kg tank.
    • Bulk in road tanker.


    • From 0.5 to 1.2 kg per 100 kg of cement.


    • Amber.


    • The possibility to prepare high performance concrete even in case of complex sand containing clay or a high percentage of fine particles, or recycled aggregates.
    • The possibility to produce concrete with very low W/C ratio (0.4) and S5 slump class, thus increasing durability.
    • It retains consistency for over an hour, depending on the A/C ratio and type of cement, even when hot temperatures or long transport times are involved.
    • The production of highly durable concretes that are resistant to attack by aggressive agents
    • Reduced entrapment of air macro bubbles ensures better surface finish.
    • No segregation or bleeding; improved uniformity and cohesion.
    • Improved quality of “exposed” concrete, concrete/iron adhesion, and resistance to abrasion.
    • Reduced creep and shrinkage; improved adhesion to rebars.
