Multiscale Poromechanics of Wet Cement Paste [PDF]

, 2019
Capillary effects such as imbibition-drying cycles impact the mechanics of granular systems over time. A multiscale poromechanics framework was applied to cement paste, that is the most common building material, experiencing broad humidity variations ...

Thermal Damage of Set Silicate Cement in Ultra-High Temperature Xerothermic Environment

Zuanjingye yu wanjingye
In coal gasification and shale gas in-situ development, the bottoms of the wellbores are in an ultra-high temperature xerothermic environment, which is of great challenge to the thermal stability of the cement sheaths.

Extensive reuse of soda-lime waste glass in fly ash-based geopolymers [PDF]

, 2018
The possibility of extensive incorporation of soda-lime waste glass in the synthesis of fly ash-based geopolymers was investigated. Using waste glass as silica supplier avoids the use of water glass solution as chemical activator.

Solidification/stabilisation of soil contaminated with metal: a review [PDF]

, 2008
Solidification/stabilisation (S/S) is generically defined as a chemical and physical alteration technique of reducing the mobility as well as solubility of contaminants in wastes in order to convert them into chemically inert form.

Crystalline phases involved in the hydration of calcium silicate-based cements: Semi-quantitative Rietveld X-ray diffraction analysis [PDF]

, 2017
Chemical comparisons of powder and hydrated forms of calcium silicate cements (CSCs) and calculation of alterations in tricalcium silicate (Ca3SiO5) calcium hydroxide (Ca(OH)2) are essential for understanding their hydration processes.

Exploring a new Portland cement-free calcium silicate cement —Part 1: Synthesis of dicalcium and tricalcium silicate

Dental Materials Journal
Mineral trioxide aggregate cement is an excellent pulp-capping material; however, its base Portland cement contains highly toxic elements and is expensive. This study aimed to explore the possibility of using calcium silicate cement without Portland cement.
