15th September

Today we made brock layers and we put mortar in the layers. Mortar is made out of water, sand and concrete mix: 4 spades of sand, 1 and 1/2 spades of cement mix and 3/4's of a bucket of water. Add sand and cement together and mix until cement is mixed in properly. Add water gradually until it is like quick sand and drops off your hand easily.

We had four layer of blocks with 10 in each layer. Two double blocks at the start with 8 single blocks around it to form a U shape.

We used three wheel barrow loads of mortar to join the blocks. On the last layer we had to cut the reinforcing steel rods with a hack saw so they were below the top of layer of blocks.

Tomorrow we will give the blocks a light spray of water so it doesn't dry to quickly,. (The slower the mortar drys the harder it becomes).

On Thursady we will be filling the triangular gaps at the back of the U shape and the square holes of the blocks with concrete.
