1. We mix the cement and sand as per the requirement of particular work.

2.The properties of sand changes with change in temperature like it becomes cold at night and warm at day time this will affect the cement strength in case of premixed.

3. It will be costly as the transportation charges based on per bags.

If we mix design is particular ratio of cement and sand then we sell by combination. But as per Code of practices we have different ratioes of cement and sand in calculation.  thats why we don't sell by combination
