Abstract:
The main reasons for using superplasticizers in precast concrete are to improve the physical properties of either the fresh or hardened concrete, to faciliate the placement and compaction of concrete in intricate moulds, to obtain better finishes or to reduce the costs of these operations. The examples described in this paper illustrate the uses of superplasticizers for more than one of these reasons.
