Abstract

An a.c. impedance technique was applied to the investigation of crack growth mechanisms in portland cement and cement-silica fume pastes, mortars and cement-wollastonite micro-fiber reinforced systems during compressive loading. It was demonstrated that the high frequency arc in the complex plane is very sensitive to microstructural change and micro-cracking in the specimens subjected to compressive load. The experimental results indicate that micro-cracking in different cement-based materials depends on their intrinsic microstructural characteristics.

AC impedance spectroscopy characteristics of chloride-exposed cement pastes
2020, Construction and Building Materials
Citation Excerpt :
During these measurements, bulk resistance or DC resistance is mostly obtained and limited electrochemical properties are able to be studied. The application of AC impedance spectroscopy, especially the establishment of electrical circuit model provides more information on the microstructure [14–16] and interfacial properties [17] of testing samples besides the bulk resistance. Besides the capacitance related to electrolyte-electrode interface in most electrochemical systems, the electrical double layer (EDL) formed at the interface of solid and liquid within cement-based materials will also generate capacitance.
In this paper, the characteristics of AC impedance spectroscopy of cement paste immersed in chloride solution were measured and analyzed with a proposed equivalent circuit model. The elements in the proposed equivalent circuit, including the resistance of interface between electrode and specimens, resistance of continuous and discontinuous pore, capacitance of solid phase and electrical double layer (EDL) were discussed. The results showed that the resistance of interface between electrode and testing specimen was much lower than that of cement paste. With the increase of chloride concentration in the soaking solution, the resistance of continuous gradually decreased due to the higher conductivity of chloride solution. Stripped out the impacts of concentration of pore solution on resistance of pores, the resistance of continuous pore increased firstly due to the decrease of continuous pore volume from the formation of Friedel’s salt. However, the resistance of discontinuous pores gradually decreased with the increase of soaking solution concentration due to the transformation of continuous pores to discontinuous pores. The reaction between chloride ions and hydration products and formation of Friedel’s salt decreased the porosity of cement pastes and led to higher capacitance of solid phase. Based on an idealized two-plate capacitor model for EDL, the thickness of EDL was calculated from the measured capacitance. The decrease of EDL thickness with chloride concentration in soaking solution was in agreement with the results of chloride contents in EDL obtained from pore solution expression test.
Synergistic approach to quantifying information on a crack-based network in loess/water material composites using deep learning and network science
2019, Computational Materials Science
Deep learning and network science are applied in a synergistic manner to address structural crack issues with the aim of providing the characteristic features of crack generation and a quantitative description of crack networks in natural materials. Loess/water mixtures were chosen as a model system due to the facile formation of cracks resulting from water evaporation. Deep learning algorithms are applied to the detection and classification of edges and nodes in cracks forming in the drying stage of the loess/water mixture system. Deep learning is shown to effectively detect and classify cracks in terms of nodes and edges. Based on the guided information on nodes and edges, cracks were subject to a connectivity analysis with network science.The combined deep learning/network science approach is proven to be suitable for understanding crack formation and propagation in both qualitative and quantitative aspects.
A review on microstructural characterization of cement-based materials by AC impedance spectroscopy
2019, Cement and Concrete Composites
As a non-destructive method, AC impedance spectroscopy is a promising technique for the characterization of cement-based materials owing to its advantages in real time monitoring. In this paper, the equivalent circuit models in publications applied for different cement-based systems are summarized. The determinations of hydration properties, microstructural changes and chloride induced corrosion parameters of cement-based materials by AC impedance spectroscopy measurements are reviewed. With some appropriate models, the AC impedance parameters can be applied to characterize microstructure and interfacial properties of cement-based materials. The experimental condition control and data analyses are discussed. Some improvements for measurement device and development of equivalent circuit models for different kinds of binding materials are needed.

2018, Non-destructive Testing and Evaluation of Civil Engineering Structures
The electrical measurement techniques in concrete were initially developed mainly for the diagnosis of steel corrosion. By extension, they have undergone developments focusing on the characterization of the concrete and the indicators of damage. The electrical resistivity of concrete is strongly conditioned by its porosity, its water state and the salinity of the interstitial solution. These three parameters are also major factors conditioning or revealing the alterations of the concrete. Measurement of electrical resistivity has become a means of assessing the condition of the material.
Influence of slag incorporation on electrochemical behavior of carbonated cement
2017, Construction and Building Materials
A research work is carried out to understand the influence of slag incorporation on the electrochemical behavior of carbonated cement systems. Measurement of carbonation depth and electrochemical impedance spectroscopy is conducted. A suitable equivalent circuit model is applied to fit the measured electrochemical impedance data (Nyquist curve) and quantitatively obtain the electrochemical property for carbonated slag blended cement. Test results demonstrate that increasing the slag replacement ratio in cement can increase the carbonation depth, enlarge the semi-circle of the Nyquist curve, and improve the resistance of ion transfer at the “solid-liquid phase” interface. We also compare the slag incorporation effect on the electrochemical system of carbonated cement with another common mineral admixture (i.e. fly ash). It is found that slag blended cement exhibits smaller semi-circle of Nyquist curve and larger carbonation depth than fly ash blended cement. Based on the electrochemical modification, we also predict the carbonation depth of blended cements with different slag contents.
