Notes
(1) typically the concrete may be used for a farm reservoir's floor-slab, the mortar to construct its wall of bricks/blocks, and the plaster for rendering the walls to improve the water retention of the reservoir.
(2) The concrete mix given here should have a strength of 25MPa providing no inferior quality sand, stone, or cement has been used, using just enough water consistent with full compaction. (Too much water results in drying shrinkage cracks, while too little water results in voids - both these conditions are to be avoided).
