Disintegration property is an important parameter for evaluating the performance of pesticide water dispersible granules (WDGs). The purpose of this study is to explore the effects of pore size and pore-size distribution formed during granulation and the drying process on the disintegration property of WDGs. It was found that the pore sizes of 10% difenoconazole WDGs, prepared by adding NH 4 HCO 3 as the pore-forming agent, were mostly within 4-25 µm. Among different drying methods, the vacuum-drying technique was responsible for a bigger capillary porosity, due to the more rapid evaporation of water. Larger pore sizes of WDGs prepared with a stronger hydrophobic polycarboxylate dispersant were obtained, as the water evaporation rate increased with increased hydrophobicity of WDGs during the drying process. The disintegration results of WDGs confirmed that a larger pore size was advantageous to the disintegration. Thus, we suggest that pore size is the key factor that significantly influences WDG disintegration performance.

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.

“…Ren et al [2] utilized the images from the micro-CT analysis to develop 2D meso-scale FE models to simulate crack propagation processes in concrete under uniaxial tension loading. There were also several attempts to study the porosity of concrete [3], ceramics [4] or soil [5]. Liu et al [6] presented an imaging method to assess the homogeneity of asphalt concrete using X-ray computed tomography whereas Steppe et al [7] applied computed microtomography for non-invasive determination of wood anatomical characteristics.…”

Abstract:The aim of this paper is to present an example of the material microstructure characterization with the use of X-ray micro-CT and nanoindentation measurements. Firstly, the current scope of application of the aforementioned techniques is provided within different fields of science. Then, background of each of the methods is presented. The methodology of X-ray micro-CT is described with the emphasis on the Beer's law formulation. In addition, the basics of the nanoindentation technique are outlined and major formulas for the hardness and Young's modulus calculation are given. Finally, example results for a concrete sample are presented. The microstructure of the selected material is firstly characterized in terms of geometry using the results from the microtomograhy measurements, e.g., porosity and attenuation profiles, pore and aggregate size distribution, shape factor of pores, etc. Next, the results of the nanoindentation tests are provided, namely the hardness and Young's modulus versus the height of the sample. The influence of the number of tests and statistical analysis on the final results is underlined.
