Hydrophobizing plasticizer for pavers and wetcast
Ha-Be Betonchemie GmbH & Co KG has broadened its surface protection product range with the hydrophobizing plasticizer Antipor® aqua proof. The new product combines various advantageous effects. It hydrophobes the concrete, improves its compactability and increases the concrete’s final strength. The plasticizer is suitable for both, manufacturing wet-cast elements and fabricating paving stones.
Analysis and tests in concrete plants confirm that concrete stones produced with the latest plasticizer from Ha-Be present a severly reduced water penetration particularly compared to other hydrophobic agents. Thereby the occurrence of unwanted efflorescence is minimized and the freeze-thaw resistance is considerably increased.
The improvement of concrete’s compactability is obvious and can even be recognized by the eye. “The stones manufactured with the new plasticizer have a lower height than concrete stones manufactured with other products.” said Thomas Henke, head of department surface protection at Ha-Be. Increased compactability can also be seen at the closed vertical structure. Antipor aqua proof ensures a homogenous structure and minimizes the occurrence of porous surfaces.
Additionally tensile splitting strength measured 28 days after production obtained Antipor-stones have a 20 % higher strength than the comparative stones manufactured with conventional products.
Antipor aqua proof is a ready to use admixture that is added into the ready mixed concrete mixture. Being dosed like conventional admixtures, concrete plants are mostly already equipped with a suitable dosing system. “Therefore costs for an appropriate equipment does not emerge” Henke states.
