The first step in making concrete is to prepare the cement. One type of cement, Pordand cement, is considered superior to natural cement because it is stronger, more durable, and of a more consistent quality. To make it, the raw materials are crushed and ground into a fine powder and mixed together.

The concrete mix should be used within two hours of mixing and must never be retempered by mixing in additional water, as this reduces the resultant strength of the mix. Moulding: Adequate care must be taken when compacting the concrete in the moulds of the blockmaking machine. Too little or poor compaction will result in greatly reduced ...

A concrete paver typically use a "slipform" process to pave roadways, first spreading fluid concrete placed on the grade with an auger, then removing excess material with a strikeoff plate. Hydraulic vibrators consolidate the concrete, and tamper bars push the large aggregate below the surface. The paver's profiling plans then set the finished elevation and provide an initial finishing of the ...
