Abstract:
The evolution of early-age structure in fresh cement-based materials fundamentally involves a transition from a suspended dispersion system to a porous medium, accompanied by changes in the energy state of the internal water. Monitoring pore water pressure (PWP) evolution reflects these changes in water energy state and provides insight into the underlying mechanisms governing the development of early-age performance in cement-based materials. Building on concepts from soil physics, this paper examines the thermodynamic mechanisms driving PWP evolution during the early stages of cement-based materials' formation. It further synthesizes advances in PWP testing methodologies and instrumentation for cement-based materials, alongside their applications in both fundamental research and engineering practice.
