Clx 700

Mortar for concrete surface protection

DESCRIPTION
Premixed powder mortar based on high resistance cements, selected inerts and redispersible dispersant copolymers with the addition of synthetic fibres. The addition of special polymers greatly improves the mortar rheology and physical properties, such as its flexural strength, with the consequent reduction in both instantaneous and permanent deformations induced by the support. The product is formulated to restore the surface layer of the concrete structures, after treating the oxidized steel reinforcement rods and restoring the concrete cover with a thixotropic mortar CLX 400. The mortar can also be used as a protective layer on new concrete if it is particularly exposed to atmospheric agents.


USES AND APPLICATION PROCEDURE
Mix with clean water in a concrete mixer or by paddle mixer until a homogeneous paste is obtained and the water is completely absorbed; extended mixing times involve an excessive formation of air bubbles in the mixture. Apply by hand or by using a proper plastering machine.
