Complex antifreeze is a water-reducing, high early strength, lower the freezing point, to prevent frost and other components made of Non-Chlorinated compound antifreeze, Powder shaped, A high early strength, frost, reducing water, air-entraining, anti-corrosion and other features. Concrete required incorporation of this agent, Can significantly improve the structure of the pores, Reduction of free water, Effectively reduce the freezing point of concrete. The promotion of low-temperature conditions, the hydration of cement and concrete hardening, Substantial increase in early strength, Mid-and late strength continued to grow, is the ideal additive species for construction in winter.
Main Technical Performance: 1, Dosage range: Dosage for the cementing material dosage 2.0-3.5%, Water-reducing rate is 15-25%. 2, The product is chlorine-ammonia-free and low-alkali type composite antifreeze, With the dual role of frost and reduce water, Will not be caused by steel corrosion as mixed antifreeze. By adjusting the dosage can be used to adapt to 0 celsius - 20 celsius in winter coagulation construction requirements. 3, The product uses a new type of antifreeze components, Significantly reduce the alkali content, To avoid mixing of soil alkali-aggregate reaction. 4, This product can be mixed with soil mixed with greatly improved the workability, Improve and enhance the physical and mechanical properties of concrete, improve freeze-thaw resistance of concrete, More suitable for the preparation of a concrete pumping antifreeze requirements. 5, Applicable to all kinds of reinforced concrete and prefabricated units which below C50, Preparation of above C50 concrete can be in conjunction with superplasticizer or require our company to adjust.
Use 1, Please follow the "application of technical specifications of concrete admixtures, " the provisions of the construction. 2, after pouring covered with plastic sheeting and straw mat surface, Do not make an immediate cold or cracks due to excessive wind. Into the mold temperature should be controlled at 5 celsius or more. 3, require rapid increase in early strength Shike Jia heat conservation, After the concrete in forming the surface of ice will not cause damage, after ambient temperature increased, Intensity is still growing rapidly.
