Concrete surface retarder
Performance metrics
◆ Water based products, safe and environment-friendly, easy to operate.
◆ Applicable to different site conditions and formwork surfaces, including steel formwork, bamboo plywood and wood formwork. It is unnecessary to roughen the concrete surface by mechanical methods such as iron cone or chisel, so as to greatly reduce the labor intensity and save the construction cost.
◆ The thickness / etching depth of retarding concrete (which can be adjusted as required) can be up to more than 10mm.
◆ Do not reduce the strength of the concrete body and the holding force to the reinforcement.
◆ No corrosion to steel formwork and reinforcement.
◆ Good surface retarding effect can also be achieved for steam cured concrete.

classification:
Concrete surface retarder is a brush-type paste surface retarder, it is a variety of cement retarder active components formulated, environmentally friendly water-based environmentally friendly products, directly coated in the template, greatly delaying the concrete surface of the condensation. When the internal concrete reaches sufficient strength, the surface of the concrete can be easily rinsed off with water due to the delayed setting, thus exposing the internal aggregates.
Scope of application
1. Concrete surfaces of prefabricated components in the field of assembled buildings that require exposed aggregates on the connecting surfaces
2. Connection surfaces of precast concrete panels for bridges, etc.
3. Pervious pavement with exposed aggregate.
