Whilst easily the best ice melt safe for concrete calcium chloride is one the more expensive options.
Calcium chloride ice melt concrete.
It is considered one of the more environmentally safe ice melt products.
Calcium chloride is fast acting forming a brine quicker than most similar ice melts.
This heat quickly melts the ice and snow thus turning it into water.
Being a hygroscopic compound it absorbs moisture and thereafter starts dissolving.
This calcium chloride formula is exothermic meaning it generates heat from within to penetrate through snow and ice.
The dissolving process is exothermic and generates heat of up to 60 degrees celsius.
