Android Giveaway of the Day - Cement and concrete dosing

I need to have a powerful tool for my work made me offer you this application.
This calculation cement dosage for the concrete, concrete, tile, mortar, screed, masonry, concrete and clean foundation.
It calculates:
- The total volume for possible control M3 materials.
- The different ingredients depending on the type of structure (foundation slab and screed ...).
- Depending on the useful volume that serves the mixture (wheelbarrow, bucket, mixer or trough) count the number of times to perform the work.
- And the quantities to fill this useful volume with optimum way to make the right choice of loading (bucket, shovel or weight).

good work and good courage for your work.
