    I found a supplier of sand/salt here but the sand is more of a squeegee mix, about 1/4"-3/8" aggregate. I thought the sand portion would be almost a masons sand. Which should it be?

    Also, the mix is 20% salt to sand. How long should it take to see active thawing in 10-20 degree temperatures? I put some down yesterday on a portion of my contract that had ice and didnt see any active thawing even after an hour in 40 degree air temps.

    I am thinking about mixing my own with a smaller aggregate and bagged ice melt. Would that be a wise idea?

    Thanks

    Salt and Sand Mix

    In Kansas City we use Concrete Sand or C33. The blend that you have would a 5-2 blend of Sand and Salt. Mason sand would be to fine and could possibly bridge in the spreader.

    Typically on coarse road salt it does not work to the best of it's ability until there is traffic basically crushing the salt causing the car to be a carrier of the salt allowing a broader area. Sodium Chloride Eutectic Temperature is -6 F which only lasts for a very short period but the effective temperature of Sodium Chloride is 5 F until it is diluted with moisture from the storm.

    Hopes this help.
