Antifreezing Concrete Admixture Small dosage: 2.0-4.0% Suitable for the winter construction

Description

JK-15 is naphthalene-based non-corrosive, non-chlorine compound antifreeze admixture which compounded with water-reducing, early-strength, reducing the freezing point, preventing freezing damage etc. ingredients, powder, it has early-strength, water-reducing, air-entraining, anticorrosion etc. functions. It is mixed to the concrete according to the request, can obviously improve the configuration of the capillary pores and reduce free-water and the freezing point of the concrete effectively. And it can accelerate cement hydration and concrete hardening under the low temperature condition, enhance the early strength greatly and make the strong more and more by time, is ideal admixture for construction in winter.

  

Advantage

JK-15 is a new generation of high efficient anti-freezing admixture. Small dosage, completely water soluble, low alkali, apparent reducing effect on the alkali-aggregate reaction. It can improve the workability, pumping properties and early strength of the concreteJK-15 is suitable for concrete and precast below C50 but also the concrete above C50 with a addition of our high range water reducing admixture.
