Hydration and microstructural characterization of early-age cement paste with ultrasonic wave velocity and electrical resistivity measurements

Hong Jae Yim et al.

Summary: This study evaluates the microstructural evolution of fresh cement paste for 24 hours through two types of non-destructive measurements and compares them with the setting time by Vicat needle test. The results show that the critical times obtained by different methods vary. XRD and TG analyses were then performed to identify hydration products at specific points.

Predicting pore volume, compressive strength, pore connectivity, and formation factor in cementitious pastes containing fly ash

Keshav Bharadwaj et al.

Summary: This paper uses thermodynamic modeling to predict the properties and reaction products of cementitious pastes containing fly ash. A pore partitioning model is utilized to estimate pore volumes and a model is proposed to quantify pore refinement. Predicted properties by the model are compared with experimental results, finding errors within 5% for porosity, 14%-46% for compressive strength and formation factor.

Fractal Analysis on Pore Structure and Hydration of Magnesium Oxysulfate Cements by First Principle, Thermodynamic and Microstructure-Based Methods

Jiasheng Huang et al.

Summary: A novel multiscale modeling strategy is proposed to simulate the hydration and pore structure of magnesium oxysulfate (MOS) cement system. The study found that large M and large H had different impacts on the formation of specific phases and the decomposition of the cement paste. Visualization of the hydration status and fractal analysis revealed the changes in pore structure after hydration.

Investigation and Application of Fractal Theory in Cement-Based Materials: A Review

Lei Wang et al.

Summary: Cement-based materials, such as cement and concrete, are the most widely used construction materials in the world. Recently, the application of fractal theory in analyzing the complex characteristics of these materials has gained global attention. The seven fractal dimensions commonly used in cement-based materials have different physical meanings and testing techniques, providing valuable insights into the macroproperties of these materials.
