the saw dust acts as an insulation against the ice and thus prevents heat by highering the melting point

saw dust act as insulator thus shield the ice from absorbing heat from the outside environment. as a result it takes long time for ice to melt.

Sawdust acts as solid impurity in the ice medium. Its addition results ina reduction of the vapour pressure of ice. This in turn causes a depression of the freezing pt of ice. So it takes longer time to melt.

because the sand stops the ice from getting exposed to air and thus,the ice takes a longer time to melt
