Cement Concrete Blocks (5 to 1)

Fixed in position below water-line, bedded with neat cement. Blocks to be composed of one part cement, two parts of sand or clean gravel, two parts broken stone, and one part of stone.

The concrete for these and all other blocks is to be mixed on a suitable and proper close jointed platform which shall be kept clean and dry for the purpose, it shall be turned over twice in a dry state, and then only sufficient water shall be added to moisten the mass, and the whole turned over three times in its wet condition. When adding the water, care must be taken that none of the cement is washed away.

It is then to be filled into moulds made to exact size of blocks required and well punned ; during filling one part of stone may be added, care being taken to place the stones well apart. Under no circumstances must the work be stopped during filling of a mould.
