Maturation of fresh cement paste within 1- to 10-m-large formworks
Source abstract
Abstract
The objective of this research was to examine the maturation of early-aged cement paste through the survey of the evolutions of the total lateral pressure exerted by cement paste against formworks and of the pore water pressure. The experimental device was specially developed for this purpose. Three types of cement paste mixtures with a water/cement (W/C) ratio of 0.30, 0.36 and 0.45, respectively, have been tested. In addition, temperature and setting kinetics were also examined. The results have shown that the kinetics of the pore water pressure and the total lateral pressure were strongly affected by the W/C ratio, the vibration and the level of stress, to which the fresh cement paste is subjected. The confrontation of these results with the theory currently available as regards setting of cement makes it possible to identify the physicomechanical phenomena, which occur within formworks.
