TamCem AE200 is an air-entraining admixture for concrete applications meeting the requirements of EN 934-2. TamCem AE200 creates small, uniformed and stable air bubbles within the wet concrete matrix that remain present after hardening. By entraining this uniformly spaced air, hardened concrete with greater durability and freeze/thaw protection is created. Furthermore, TamCem 200AE offers improved mix workability and surface finishing.
