Work continues on the foundation of the school. As I understand it: powdered cement is mixed with sand and water to form mortar. To this same mixture is added stones which makes concrete. Different rations are used depending on the desired usage. All this is done by hand (shovels) on the ground in large piles and then transported to the correct trench with buckets.
Today we worked to add the 2nd (and in some places the 3rd) layer of brick to the 1st that we finished on Saturday.

This first picture shows the first layer of brick resting on the poured foundation. (The work we finished on Saturday.) The picture is looking down into a 5 foot trench. Mortar connects each brick in the line.


This second picture shows the bricks being filled in with concrete. This eliminates any gaps in the brick.


This third picture shows the 1st layer of brick with the holes now completely filled and dry. Notice that the rebar (steel skeletal rods) are through each brick giving it strength.


This fourth picture shows the 2nd layer of brick now being laid on top of the 1st. A steel rod goes through each brick, mortar is placed between each layer and between each brick, and concrete will fill the gaps within the brick.
