POBphotocontest New Round: SAND

This photo was taken with my Redmi 9a and represents a sand bank in the doorway of a house under construction. There you can see several phases for the use of this mineral in the different types of mixtures with the cement

In the background the sand with all its components at the moment of being extracted from the quarry and in the foreground the granzon with stones and coarser sand. The lump of sand is contained around it by concrete blocks, wood and other materials to prevent it from spilling. Sand is a primordial element in any type of construction, from the base to the roof.
