<jats:title>Abstract</jats:title>
<jats:p>Rock pore is the storage space and migration channel of geo-fluid resource like petroleum, coalbed methane and shale gas etc. In this paper, the rock core microscopic pore structure based on CT image is studied through image processing. Then the parameters are analyzed statistically by numerical modelling. The reconstructed software Mimics is used to reconstruct the core structural model. Finally, the relationship between the pore structure parameters and penetrability is studied by numerical simulation. The equivalent permeability of the reconstructed core is calculated by using FEM software Abaqus. The results shown that fluid percolation is directly related with porosity, pore shape, pore conectivity. The permeability of core can be obtained by substituting flow numerical simulation for seepage laboratory experiment.</jats:p>

摘要：
A study presented findings on the behavior of ordinary concrete against superabsorbent polymers (SAPs) SAPs-modified concrete. Specimens were evaluated for resistance to freeze-thaw, shrinkage, and sulfate attack. Scanning electron microscopy (SEM) was utilized to investigate the modification mechanism. The cement used to prepare concrete samples was No. 42.5 Portland cement. The fine aggregate was a medium-coarse sand with a fineness modulus of 2.7 and a density of 1.57 × 103 kg/m3, in accordance with the specifications of JGJ 52-199. Tap water was utilized for all concrete samples. A base water/cement ratio of 0.4 was used to prepare specimens that incorporated 0.0, 0.1, 0.3, 0.5, 0.7, and 0.9% of the SAPs as concrete additives.
摘要：
A study was conducted to verify the validity of silane as an additive by monitoring the corrosion behavior of silane-enhanced mortar. Silane coupling agents were used in varying proportions, and the effect of the coupling agent content on mortar properties was studied. The integral silane mortar additive was (γ-glycidoxypropyl) methyldimethoxysilane (KH560). River sand with a fineness modulus of 2.43 was used as the fine aggregate. A water/cement ratio of 0.4 was used for preparing mortar mixtures incorporating no silane (the reference sample), and 1, 3, and 5% silane. Distilled water was used to prepare the mortars.
摘要：
A microemulsion was successfully prepared via polycondensation of alkoxy silanes. Research into the control of the preparation and properties of the microemulsion was conducted. The structure and properties of the microemulsion were characterized by transmission electron microscopy (TEM) and photon correlation spectroscopy (PCS). The variation in the temperature, the methods, and the amount of catalyst and surfactant was studied in relation to the properties of the final microemulsion.
摘要：
This paper studies the mixture of cement mortar with a phase change material (PCM) and analyzes the changes in mechanical and physical performances. The experimental results demonstrate that an increase in PCM content results in decreases in consistency, compressive strength, bulk density and water retention. Therefore, these results can provide a reference for the application of phase change materials in practical engineering conditions.

摘要：
A new method, Dynamic Leaching Test (DLT), was put forward to analyse the leaching behaviour and leaching mechanism of heavy metals in solidification body of municipal solid waste incineration (MSWI) fly Ash. In this study, two groups of solidification materials were used, one with ordinary Portland cement (C), and the other with slag-and-clinker (SC). In each solidification body, solidification material/ (solidification material + MSWI fly ash) weight ratio was 25% and water/solid weight ratio was 0.3. After a 60-day curing period, DLT was applied to analyse the leaching behaviours and leaching mechanisms of lead and chromium in solidification body with a mathematical model based on Fick's first law. The test results showed that most of lead and chromium were leached out during the initial stage (0∼7d), and their leachability decreased greatly later. In the cement-based solidification body, the leaching behaviour of chromium is approximately consistent with Fick's first law. The leaching of lead is a combination of diffusion and acid erosion mechanisms. In the slag and clinker-based solidification body, the leaching of lead is approximately consistent with Fick's First law. The leaching of chromium is more complicated than simple diffusion or acid erosion, which indicated the need for further research.
