Abstract
An experimental investigation was performed to determine the hydraulic pressure variation of cementitious based materials (cement paste, concrete, SCC, etc.) during the plastic phase. A method based on measurements of both total lateral pressure and hydraulic pressure, using a novel device, has been investigated. Just after mixing, a simultaneous drop of both the hydraulic and the total lateral pressures was recorded, followed by a cancellation of total lateral pressure and a negative value of hydraulic pressure. Compared to other standard methods (Vicat, calorimetry, ultrasonic pulse-echo, ), the presented device was able to give simple and direct information about the mechanical state of the material, in situ. The kinetics variation of the hydraulic pressure occurring during the plastic phase of cement pastes using two portland cements fractions and a limestone filler was investigated. We compared the results obtained with the cement pastes with a SCC and a traditional concrete. To evaluate the in situ performance of the novel hydraulic pressure device data were obtained on a construction site. To relate the hydraulic pressure measurements with workability, a study on the evolution of the rheology of the cement paste was conducted. The simultaneous variations of rheological parameters and pressures are discussed and some conclusions are drawn on the possibilities of this approach.Proceedings Title
