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 ...

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.

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 By-Product of Alumina Extraction from Fly Ash as Silicate Fertilizer [PDF]
, 2021 Calcium silicate hydrate is proposed as a potential silicate fertilizer. It is the main phase of the by-product of a mild hydrochemical process used to extract alumina from coal fly ash. Its preparation by decomposing sodium calcium silicate hydrate, the

The Atomic-Level Structure of Cementitious Calcium Silicate Hydrate [PDF]
, 2017 Efforts to tune the bulk physical properties of concrete are hindered by a lack of knowledge related to the atomic-level structure and growth of calcium silicate hydrate phases, which form about 50-60% by volume of cement paste.

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.
