“…Additional stress is also generated due to difference in volumetric changes owing to high temperature and moisture absorption between two constituent materials. These volumetric changes are responsible for producing tensile stresses at OTZ and creates a condition in which cracks readily develop [15,16]. The interfacial strength also depends upon the intrinsic properties of the constituent materials.…”

“…Thus, the proposed model is not full-intrinsic but "quasi-intrinsic" one. Figure 18 shows the comparison of experiments by Park et al (2012) and the analysis results. In this case as well as the author's experiment, the applicability of the proposed model is elevated.…”

A new method for predicting the water absorption process of unsaturated cementitious composites is proposed, and its functionality is experimentally verified. The mechanism of the capillarity on water absorption process is mathematically termed by a slip boundary condition of micro-flow of pore water, and employed to an unsaturated water permeation on the scheme of multi-scale modeling. The rapid sorption just after the exposure to condensed water is fairly simulated owing to the non-local formulation of hygro-gradient, which simply represents the thermodynamics of non-equilibrated states in dry pores. The proposed model of complexity of micro-pore connection is examined in terms of the initial water content, porosity and saturation of micro-pore structure and volume ratio of aggregate. It is further examined in terms of the intrinsic hydraulic profile by using the Boltzmann's transform.

“…For this reason, the study of the capillary suction properties of construction materials remains a matter much debated [8][9][10][11][12][13]. Its importance is connected to the analysis of their performance when installed as well as their durability [14][15][16].…”

An intermingled fractal units' model is shown in order to simulate pore microstructures as pore fraction and pore size distribution. is model is aimed at predicting capillary water absorption coefficient and sorptivity values in cement pastes. e results obtained are in good agreement with the experimental ones. For validating this model, a comparison with other procedures has been shown. It is possible to establish that the newly proposed method matches better with the experimental results. at is probably due to the fact that pore size distribution has been considered as a whole. Moreover, even though the proposed model is based on fractal base units, it is able to simulate and predict different properties as well as nonfractal porous microstructure.
