▲ Product description

　　KDNOF-5 air-entraining water reducing agent is a kind of retarding air-entraining superplasticizer formulated with a variety of surfactants by our research staff with reference to the advanced process recipes at home and abroad. This product has no chlorine, low alkali, retarding and low slump loss. Under moderate amount of dosage of this product, it can evidently reduce the concrete surface tension, improve the workability of concrete and reduce  water bleeding and segregation. Meanwhile it can enhance the concrete permeability resistance, frost and thawing resistance and durability,etc. The addition of the product into concrete can produce uniform stable tiny bubbles which is not easy to be damaged. This product is suitable for concrete engineering of ports, wharf, water conservancy project, road surface, freeze resistance, anti-corrosion, seepage resistant which requires a certain gas content.
