The concrete surface retarder comprises one or more cement retarding active components, deionized water, a rheological additive, a humectant, an antifreezing agent, a preservative, an antirust agent, a pigment or dye coloring agent and a filler.

Description

technical field [0001] The invention relates to the technical field of cement concrete retarders, in particular to a substance retarding the surface of a water-based concrete material and an application method thereof. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, people's awareness of environmental protection has become stronger and stronger. Especially with the rapid development of my country's economy in recent years, construction industrialization has emerged as the times require. With rapid development, prefabricated building components are produced in factories, which greatly reduces the dust pollution and noise pollution on the construction site, reduces the labor intensity of workers, and saves a lot of templates. Therefore, prefabricated buildings are of great significance to environmental protection and energy saving. broad. [0003] After the prefabricated build...

Problems solved by technology

[0004] The traditional surface roughening treatment is to use steel brushes, electric hammers, pneumatic picks, steel drills and other tools for construction. This construction method has high labor intensity for workers, low work efficiency, uneven exposure of aggregates, floating dust, and pollutes the environment. , high construction costs and other defects, not only time-consuming and laborious, polluting the environment, low efficiency, high cost, but also because the vibration is easy to cause cracks in the concrete and cause safety hazards

[0005] Chinese patent application CN200480030929.3 discloses an oil-based spray-on surface retarder using vegetable oil and its derivatives or animal oil and its derivatives + sugar or salt or acid, which is not environmentally friendly when washing

[0006] Chinese patent application CN104446642A discloses a kind of concrete smear type surface delay retarder, and its sagging property is poor, and construction efficiency is lower (painting when placing horizontally before formwork supports formwork, and just can support formwork after air-drying ), and it is not friendly to the environment, and the borax in the component has strong toxicity to the human body
