Distribution of Water in Synthetic Calcium Silicate Hydrates [PDF]
Langmuir, 2016 Understanding calcium silicate hydrates (CSHs) is of paramount importance for understanding the behavior of cement materials because they control most of the properties of these man-made materials. The atomic scale water content and structure have a major influence on their properties, as is analogous with clay minerals, and we should assess these ...

Nanoscale origins of creep in calcium silicate hydrates [PDF]
Nature Communications, 2018 AbstractThe time-dependent response of structural materials dominates our aging infrastructure’s life expectancy and has important resilience implications. For calcium-silicate-hydrates, the glue of cement, nanoscale mechanisms underlying time-dependent phenomena are complex and remain poorly understood.

Utilization of ZeoliticWaste in Alkali-Activated Biomass Bottom Ash Blends
Molecules, 2020 This study aims to investigate the effects of ammonium-bearing zeolitic waste (FCC) on alkali-activated biomass bottom ash (BBA). FCC was obtained from the oil-cracking process in petroleum plants.

Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The calcium silicate hydrates [PDF]
Cement and Concrete Research, 2008 This article is concernedwith the calciumsilicate hydrates, including crystallineminerals and the extremely variable and poorly ordered phase (C-S-H)\ud that is the main binding phase in most concrete. Up-to-date composition and crystal-structure information is tabulated for the most important crystalline\ud calcium(alumino) silicate hydrates and ...

Effects of slag powder/metakaolin on the early performance of natural hydraulic lime
矿业科学学报, 2022 Natural Hydraulic Lime (NHL) has exceptional application in restoring ancient buildings compared to Portland cement and conventional air-hardening lime, but the characteristic of slow early performance development limits its fields of application.
