Abstract

The permeability of concrete is becoming a focal characteristic with regard to the durability and performance of cement-based materials, pastes, mortars and concretes. Since it is mainly affected by the microstructure of the porous media, many models and theories have been developed relating the permeability of porous media to their microstructural parameters. One which proved to be useful in predicting the permeability of sedimentary rock, from mercury intrusion porosimetry data, is the Katz-Thompson theory. A review of this theory and its assumptions is presented, and its applicability to cementitious materials is investigated using two sets of data of various hardened cement pastes and concretes. Also, the major differences between cement-based materials and sedimentary rock from the microstructural point of view is reported.

Improved predictions of permeability properties in cement-based materials: A comparative study of pore size distribution-based models
2024, Construction and Building Materials
Permeability is a fundamental physical property of a cement-based material and is closely related to its pore structure. This study developed an improved model for permeability prediction of cementitious materials with a function of the pore size distribution (PSD), in which PSD is simulated from single and compound lognormal distribution functions, respectively. The efficiency of the improved model is demonstrated by calculating permeability for mortars and pastes available in the literature. It is found that, first, for cementitious materials with unimodal PSD, the single lognormal distribution function is adequate to describe the pore structures. In contrast, for cementing mixtures presenting multimodal PSD, the compounded lognormal distribution function is highly recommended to cover a wide range of pore components. Second, the permeability model based on the compound PSD can predict well permeability to gas intrusion, whereas the single PSD-based model is applicable for calculating permeability via water intrusion. Furthermore, slippage effect and water saturation degree are introduced in the PSD-based model. Results prove that the corrected gas permeability model from the compound PSD performs well in estimating the gas permeability in unsaturated states. Finally, the compound PSD-based model is extended by considering varying porosities and relative humidities, which can be used to quantitively describe permeability when cementitious materials undergoing pore structure degradation induced by durability issues.
Pore structure characteristics and permeability analysis of natural anhydrite with various water /anhydrite ratios based on mercury intrusion porosimetry
2023, Construction and Building Materials
The characteristics of the gypsum pore structure are closely related to its macroscopic mechanical properties and permeability. Recent research on anhydrite-based cementitious materials is mainly focused on modification and enhancement and their effect on pore structure characteristics, while the relationship between pore structure and permeability remains unclear. Here, we characterized the pore structure and permeability of natural anhydrite-based cementitious material under various water-anhydrite (W/A) ratios based on the mercury intrusion porosimetry, intending to investigate the relationship between these two parameters. This paper investigated the effect of the W/A ratio on the characteristic pore diameter of natural anhydrite-based cementitious materials. The hydration products optimize the pore structure through the filling effect to form a dense spatial structure, thereby improving the mechanical properties and permeability of the hardened body, where porosity is the main factor affecting the mechanical properties. The multifractal characteristics of natural anhydrite-based cementitious materials and the pore size dependence of permeability were clarified, and the thermal fractal dimension of its small pore range (4–1 600 nm) satisfied the k = aD^b relationship with the permeability coefficient based on the Katz-Thompson model, providing a novel thought for the calculation and research of the permeability of anhydrite-based cementitious materials.
Comparative study on effects of pozzolanic nano-SiO<inf>2</inf> and non-pozzolanic nano-TiO<inf>2</inf> on the microstructure and macro properties of cement paste subjected to early-age frost attack
2023, Cold Regions Science and Technology
The effects of nano-SiO₂ (NS) and nano-TiO₂ (NT) on the microstructure, strength and chloride diffusivity were compared, and the mechanism of both nanoparticles on early-age frozen cement paste was revealed. The thermogravimetric (TG) results demonstrate that NS effectively increases C-S-H gel content and degree of hydration to make up for hydration loss due to early-age frost attack, while NT had little effect on compensating for hydration loss. The mercury intrusion porosimetry (MIP) results indicate that NS and NT have the same improvement mechanism for frost-damaged pore structures, while NS has a better improvement effect on pore structure than NT. The macro results show that the enhancement effects of NS and NT on strength are similar, while the improvement effect of NS on chloride diffusivity is much better than that of NT. Finally, it is concluded that, in the early-age frozen cement paste, NS promotes cement hydration and optimize pore structure through pozzolanic effect, while NT mainly improves pore structure through nano-filling effect.
A new analytical method to predict permeability properties of cementitious mortars: The impacts of pore structure evolutions and relative humidity variations
2023, Cement and Concrete Composites
This research develops analytical models in respectively describing the water vapour sorption isotherm and permeability properties based on a probabilistic method for pore size distribution and two transformation models for pore radius of cementitious mortars. By adopting the water vapour sorption model, the water saturation degree in cement-based materials is acquired and the influence of ions on water vapour sorption isotherm is modelled by introducing the water activity in thermodynamic equilibrium relation between liquid and vapour phases. The results reveal that the presence of ions increases the susceptibility of mortars to be water-saturated. Additionally, intrinsic permeability and relative permeability of mortars are predicted and the reliability of the permeability model is investigated. Finally, the permeability model is further extended considering the evolutions of pore structure and variations of relative humidity when cementitious mortars are subjected to precipitation and dissolution, which attempts to give an understanding of interactions between permeability and evolved pore structure that are not yet very commonly mentioned in literature. Modelling results show that both pore size distribution and relative humidity significantly affect permeability properties of mortars, especially when the water saturation degree is large. This research provides a novel insight into quantifying the permeability of mortars undergoing pore structure degradations.
Experimental study on gas permeability of cement-based materials
2022, Cement and Concrete Composites
Gas permeability is an important property associated with the durability of cement-based materials. In this study, an experimental method based on applying a quasi-stationary flow is adopted to evaluate the gas permeability of cement-based materials. The results indicate that the intrinsic permeability of dried cement-based materials is affected by the addition of limestone powder, fly ash, and aggregate. The Katz-Thompson equation could predict the intrinsic permeability by using the capillary porosity, average diameter, and pore tortuosity. The intrinsic permeability of partially saturated cement-based materials decreases when the water saturation increases. The Van Genuchten-Mualem model could describe the relative gas permeability of partially saturated cement-based materials, and the model parameters n value between 1 and 2 while m value ranging from 0.64 to 0.69 for cement and mortar. Moreover, the power function relationship between the intrinsic permeability and Klinkenberg constant of cement-based materials has also been corroborated. Finally, a prediction model of gas permeability of cement-based materials under arbitrary water saturation and pressure gradient is proposed.
New sights in early carbonation of calcium silicates: Performance, mechanism and nanostructure
2022, Construction and Building Materials
Low calcium minerals were considered as a potential sustainable binder and reported to be reactive to CO₂. In this research, the carbonation characteristics of C₃S, β-C₂S and γ-C₂S at early age were investigated in some new sights. The results show that carbonation degree and compressive strength of C₃S increased most rapidly in the first 8 h carbonation, then slowed down. After 48 h carbonation, β-C₂S and γ-C₂S were close to C₃S in compressive strength, and apparently higher than C₃S in carbonation degree. The crystalline CaCO₃ generated by carbonation were mainly calcite and aragonite, while vaterite was observed in β-C₂S and γ-C₂S within 8 h carbonation. Carbonation curing increased MCL of C-S-H and silicate polymerization. Besides, based on the combination of TG-DTG, XRD and ²⁹Si NMR, the decalcify priority of Ca sites in C-S-H was analyzed. The results indicate that interlayer Ca atoms inside C-S-H participated carbonation first, then the calcium atoms within interlayer and silicate chains of C-S-H would be removed successively.
