This is for the construction of Compost Tank east of the gate for an easy access. (I wonder the visitors should not be greeted with composting smell - hope the best). The bricks are to be laid with 1 inch gap between them for proper aeration.
The tank will be having two compartments so that one will be filled with vegetable waste and allowed to compost. While the other will be slowly filling in. once the first one is turned into compost, the it will be emptied and process reversed. That's the idea. It may also happen that if there are earth worms, they can travel back and forth.
A total of 250 cement bricks at the cost of Rs. 18/- each has been purchased. Add transport etc it comes to around Rs. 5500/-. Cool. I guess by the time project ends it will be 10,000/- including mason and wages.
"In place of backed mud bricks,
this is coming out cheaper", said Subbu. The normal bricks cost Rs. 5/- each and around 800 will be required. Therefore compared to that, the cement bricks which are 3 times the size of normal bricks is a better choice. Nature lovers may however prefer normal bricks. But using flyash bricks is more eco-friendly than normal bricks which require firewood to make.
Logic is great. Anyway decision taken and implemented.
But calculations show there is not much difference in cost, but otherwise.
Cement Bricks = 16" x 8" x 4 = 512 cubic inches
Normal Bricks = 9" x 4.5" x 3 = 122 cubic inches
Therefore 1 cement brick = 4 normal brick by volume.
Therefore if 250 bricks are costing Rs. 4500/-, then equivalent 1000 should cost RS. 5000/- by same volume.
Not much difference. But there is definitely difference in weight and cost of handling etc. The normal bricks have to be brought in two/three vehicles. That will add another 1500 cost.
