Concrete surface retarder

HY-HN concrete surface retarder HY-HN01 concrete coated delayed-type surface-type retarder for concrete coated surface of the concrete rough surface processing delay retarder, in a modern building construction, concrete is essential engineering materials. The quality of all aspects of the construction of concrete mixing, transport, pouring, curing, etc., directly affect the quality and use of safety engineering. During the construction of the concrete, because of the diversity and inconsistency structure structure cross-sectional area often require multiple forms of pouring concrete to form the structural design requirements, thereby generating the old concrete Jiecha problems. In order to make good bond old concrete to become one, you must be in contact with the original concrete new concrete surface roughening process. That is, to remove the already solidified concrete exposed on the surface smooth rough surfaces. The quality of the concrete rough surface treatment directly affects the old concrete bonding effect. For the shortcomings of traditional construction technology, to provide a increase productivity, reduce construction costs HY-HN01 delay concrete surface coated type retarder. HY-HN0 application methods, according to the following steps: (1) needs to be done before the rough surface of concrete formwork formwork, with a brush or roller on the template surface smear layer delay retarder and let it air dry, so the template concrete (2) pouring concrete, concrete retarder film of water to delay dissolution, release delay retarder penetrate to the contact surface; forming a layer on a water-soluble but rough delay retarder film In summer the concrete curing three days, winter steam curing of concrete structures 10 hours; (3) pressure water washed concrete surface, so that the exposed aggregate and reach the depth of the design requirements explicit. Its advantages are: in the final setting of concrete or prefabricated steam curing after the end of the release, with the pressure of water erosion need to do concrete surface rough surface, rough surface can achieve concrete design requirements. Late binding is also pouring concrete to meet the design requirements. It replaced the original construction method cumbersome, easy to operate, other parts of the concrete without any harm, saving a lot of work time, reduce labor intensity, eliminate the dust pollution, save the financial and material resources, reduce the construction costs. Simple delay retarder production operations, subject to site constraints, and the raw materials essential for organisms to achieve a green philosophy. HY-HN01 varieties according to cement, concrete strength grade, additive type, early ambient temperature curing, flexible control of erosion and delay time amount of retarder, you can control the depth of the rough surface of the exposed aggregate, to achieve the best rough surface treatment effect. HY-HN02 sprayed concrete surface retarder packaging and specifications: 50 or 200 kg drums.
