This happens because smaller the size of the reactant particles higher is the rate of reaction

rm3456663: In the process of dilution of concentrated sulphuric acid with water,very large amount of heat is liberated. As a result,water gets evaporated instantaneously, if it is poured in to the concentrated sulphuric acid,which may cause an accident.To avoid this, required amount of water is taken in a glass container and small quantity of conc sulphuric acid at a time is added with stirring.Therefore,only a small amount of heat is liberated at a time.

This is because the tile pieces will first disintegrate into powder form then only will dissolve in HCL. But its powder is already in disintegrated form so it will automatically dissolve faster in HCL..
