Abstract:
The subject of consolidation of superplasticized concrete with flowing consistency has been studied by, among others, the Swedish Cement and Concrete Research Institute and the Dynapac Research Department. A basic question is the need for consolidation with regard to different consistencies of the mix, different applications, etc. The effect of internal vibration of superplasticized concrete mixes has been investigated in laboratory tests. The performance of internal vibration in practice is discussed. Surface and form vibration of superplasticized concrete have been studied in laboratory and field tests.
