Modeling the Early Stage Formation Mechanisms of Calcium Silicate Hydrates and Related Gels [PDF]
arXiv, 2019 Arguably the most ubiquitous construction material in modern civilization, concrete is enabling the development of megacities around the globe together with increasing living standards in developing nations. However, it can be argued that the concrete industry's somewhat empirical and conservative approach to change is hampering innovation and ...

Formation and characterization of ceramic coating from alumino silicate mineral powders in the matrix of cement composite on the concrete wall [PDF]
Materials Chemistry and Physics, 2019, 2018 Enhancement of thermal performance of concrete wall is nowadays of great importance in reducing the operational energy demand of buildings. We developed a new kind of inorganic coating material based on \ce{SiO2}-\ce{Al2O3}-rich minerals and Portland cement (PC) powder. The finely pulverized mineral powder with the particle size distribution (PSD) of 0.

Is Cement a Glassy Material? [PDF]
arXiv, 2015 The nature of Calcium--Silicate--Hydrate (C--S--H), the binding phase of cement, remains a controversial question. In particular, contrary to the former crystalline model, it was recently proposed that its nanoscale structure was actually amorphous. To elucidate this issue, we analyzed the structure of a realistic simulation of C--S--H, and compared ...

Odontogenic effects of a fast-setting calcium-silicate cement containing zirconium oxide.
Dental materials journal, 2015 A fast-setting calcium-silicate cement (Endocem) was introduced in the field of dentistry for use in vital pulp therapy. Similar to mineral trioxide aggregate (MTA), it contains bismuth oxide to provide radiopacity.
