The objective of this paper is to investigate the characterization of moisture diffusion inside early-age concrete slabs subjected to curing.
Time-dependent relative humidity (RH) distributions of three mixture proportions subjected to three different curing methods (i.e., air curing, water curing, and membrane-forming compounds curing) and sealed condition were measured for 28 days.
A one-dimensional nonlinear moisture diffusion partial differential equation (PDE) based on Fick’s second law, which incorporates the effect of curing in the Dirichlet boundary condition using a concept of curing factor, is developed to simulate the diffusion process.
Model parameters are calibrated by a genetic algorithm (GA).
Experimental results show that the RH reducing rate inside concrete under air curing is greater than the rates under membrane-forming compound curing and water curing.
It is shown that the effect of water-to-cement (w/c) ratio on self-desiccation is significant.
Lower w/c ratio tends to result in larger RH reduction.
RH reduction considering both effect of diffusion and self-desiccation in early-age concrete is not sensitive to w/c ratio, but to curing method.
Comparison between model simulation and experimental results indicates that the improved model is able to reflect the effect of curing on moisture diffusion in early-age concrete slabs.
