Abstract
The invention relates to the technical field of anti-freezing agents, particularly to a concrete anti-freezing agent. The concrete anti-freezing agent is formed by the following raw materials of, by weight, 15 to 25 parts of poly carboxylic acid water reducing agents, 5 to 10 parts of sodium lignin sulfonate, 5 to 10 parts of alkyl glycoside, 0.3 to 0.8 part of tea saponin, 3 to 6 parts of sodium gluconate, 0.1 to 0.5 parts of sodium dodecyl benzene sulfonate, 6 to 12 parts of calcium formate and 30 to 40 parts of water through preparation. According to the concrete anti-freezing agent, the adaptability to concrete is good, the quality is stable, the product is environmentally-friendly, various engineering requirements can be met, and the concrete can be maintained not to freeze at minus 30 DEG C to minus 20 DEG C.
Description
technical field [0001] The invention relates to the technical field of antifreeze, in particular to a concrete antifreeze. Background technique [0002] In winter construction in northern my country, in order to ensure the quality of the project and prevent concrete from freezing damage, two protective measures are mainly taken. One is to use covering or enclosure heating methods to prevent the concrete temperature from dropping below 0°C. This method is costly and complicated to operate; The second is to add antifreeze to the concrete. This method is simple in construction and good in effect, so it has been widely used in our country. [0003] So far, the pumping antifreeze used in construction projects at home and abroad are all formulated with water-reducing components, compounded with early-strength components, antifreeze components and air-entraining components. Among them, the water-reducing components include naphthalene sulfonate formaldehyde condensate (naphthalene-...
