INFLUENCE OF THE PASTE AND AGGREGATE RESPECTIVELY ON THE MEASURED RHEOLOGICAL CHARACTERISTICS OF FRESH VIBRATED CONCRETE

INFLUENCES RESPECTIVES DE LA PATE ET DES GRANULATS SUR LA MESURE DES CARACTERISTIQUES RHEOLOGIQUES DU BETON FRAIS VIBRE

The exclusively viscous behaviour of pure cement paste subjected to vibration can be determined by classical viscometric methods. In this communication the authors have sought to determine the effect on these measurements, of the presence of aggregates exceeding 100 microns in size. For this purpose they have established laws which govern the effect of the addition of aggregates on the viscosity of pure cement paste. It is shown in particular that the presence of aggregates in a pure paste tends to produce a mixture which less and less satisfies the conditions necessary for viscometric measurements, as the concentration and size of the aggregates increase. In a wider sense, it is stated that it is not possible to speak of a possible viscosity of concrete, and consequently that it is futile to attempt to carry out viscometric measurements on this material. /TRRL/
