Description
YL-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.
Uses
YL-15 is suitable for the winter construction (in ambient temperatures ranging from -5 ℃ degree to -20 ℃degree) of common concrete, pumping concrete, large volume concrete and ready mixed concrete.
