Nanostructure of calcium silicate hydrates in cements.
نویسندگان
چکیده
Calcium silicate hydrate (CSH) is the major volume phase in the matrix of Portland cement concrete. Total x-ray scattering measurements with synchrotron x rays on synthetic CSH(I) shows nanocrystalline ordering with a particle diameter of 3.5(5) nm, similar to a size-broadened 1.1 nm tobermorite crystal structure. The CSH component in hydrated tricalcium silicate is found to be similar to CSH(I). Only a slight bend and additional disorder within the CaO sheets is required to explain its nanocrystalline structure.

Estimation of the Elastic Properties of Important Calcium Silicate Hydrates in Nano Scale - a Molecular Dynamics Approach
Approximately, 50 to 70 percent of hydration products in hydrated cement paste are polymorphisms of C-S-H gel. It is highly influential in the final properties of hardened cement paste. Distinguishing C-S-H nano-structure significantly leads to determine its macro scale ensemble properties. This paper is dealt with nano-scale modeling. To achieve this, the most important C-S-H compounds, with a...
متن کاملSolubility and Structure of Calcium Silicate Hydrate
A poorly crystalline class of calcium silicate hydrates known as CSH possesses extensive disorder and structural variations at the nanometer scale. The extent of these variations has generally obscured a comprehensive understanding of the CSH nanostructure, but new relationships between solubility and structure appear to shed new light on this old problem. These relationships were inspired ...
متن کاملVital pulp therapy with two different calcium-silicate cements: two cases report
It is a worthy aim to preserve the pulp vitality in teeth with immature root in order to continue the root's maturation. Traumatic injuries and caries are two main reasons for pulp exposure in immature teeth. This article describes two vital pulp therapies on two patients, a nine-year-old boy with traumatized central tooth and a 10-year-old boy with caries exposure in a premolar tooth. Both tee...
متن کاملCesium and Strontium Retentions Governed by Aluminosilicate Gel in Alkali-Activated Cements
The present study investigates the retention mechanisms of cesium and strontium for alkali-activated cements. Retention mechanisms such as adsorption and precipitation were examined in light of chemical interactions. Batch adsorption experiments and multi-technical characterizations by using X-ray diffraction, zeta potential measurements, and the N₂ gas adsorption/desorption methods were conduc...
متن کاملCreep of a C-S-H gel: a micromechanical approach.
Both clays and calcium silicate hydrates(the main hydration products of Portland cements) exhibit a microstructure made up of lamellar particles. The microscopic mechanism responsible for the macroscopic creep of such materials is often described as the relative sliding of the sheets. This paper proposes a micromechanical approach to estimate the macroscopic creep behavior rising from this micr...
