Transient and steady states of Gd2Zr2O7 and 2ZrO2∙Y2O3 (ss) interactions with calcium magnesium aluminium silicates [PDF]

, 2019
Reactions between calcium magnesium aluminium silicates (CMAS) and Gd2Zr2O7 or 2ZrO2∙Y2O3 (ss) are investigated within a temperature range of 1200–1300 °C and for durations of 1 h–100 h. The evolution of CMAS penetration depth in Gd2Zr2O7 and 2ZrO2∙Y2O3 (

Interaction of calcium lignosulfonate with tricalcium silicate, hydrated tricalcium silicate, and calcium hydroxide

Cement and Concrete Research, 1972
Abstract Tricalcium silicate, bottle-hydrated tricalcium silicate and calcium hydroxide were each treated with 0.015–1.0% calcium lignosulfonate (CLS) using water or dimethyl sulfoxide. At low CLS concentrations C 3 S hydrates and irreversibly adsorbs CLS. At concentrations beyond about 0.25–0.35% the hydration of C 3 S is inhibited.

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

Calcium silicates and their surface layers in aqueous electrolyte solutions

, 1968
In a survey of Ca silicates and hydrated silicates it is shown that the following compds., some of which are important in portland cement, occur in the CaO-SiO2 phase diagram: modifications of SiO2 with O2-ions in bridging positions; CaSiO3 with endless ...
