◆ Concrete surface with exposed aggregate is required for the connection surface of prefabricated components in the field of prefabricated buildings;
◆ Connecting surfaces of precast concrete panels such as bridges;
◆ Exposed aggregate permeable pavement.
Advantage
◆ 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.
