Despite more than a century of research, drying shrinkage still causes unwanted stresses
and cracks in our concrete infrastructures. This is partly due to the lack of understanding of …

The fundamental chemical hydration process of portland cement and its main mineral
component, tricalcium silicate, was studied by investigating the effects of various additives. A …

In recent years, continuum and atomistic modeling of cementitious materials has provided
significant advances towards studying the durability of civil infrastructure. An important …

This paper investigates the applicability of nucleation and growth mechanisms to the
hydration of alite. Various possible mechanisms of nucleation and growth were simulated …

With shear interest in nanoporous materials, the ultraconfining interlayer spacing of calcium–
silicate–hydrate (C–S–H) provides an excellent medium to study reactivity, structure, and …

The basic building block of calcium-silicate-hydrate (C–S–H) gel, which is the major
hydration product of a commercial Portland cement paste, is usually referred as “globule” in …

Portland cement reacts with water to form an amorphous paste through a chemical reaction
called hydration. In concrete the formation of pastes causes the mix to harden and gain …

In the appropriate concentration range, three-component systems of polar, nonpolar and
amphiphilic molecules can result in isolated nanoscopic droplets of the polar phase …

The transport properties of water and ions play a key role in the durability of cement-based
materials. However, little work has been done to study the diffusion behaviors of water and …

Since Roman times, cement is one of the synthetic materials with the largest production and
usage by mankind. Its properties allowed the expansion of the Roman Empire and the …
