The hydrated calcium silicates

Eos, Transactions American Geophysical Union, 1937
The hydrated‐calcium silicates are of particular geological interest as typical minerals formed by hydrothermal reactions at contact‐zones of different mineral species. They are also of technical significance as compounds which may be formed in the steam‐treatment of Portland cement and pozzolanic materials and in the manufacture of sand‐lime brick. To

Microstructure of calcium silicate hydrates

Cement and Concrete Research, 1971
WHILE CONSIDERABLE ATTENTION AND STUDY HAVE BEEN DEVOTED TO THE STRUCTURE AND MORPHOLOGY OF CALCUM SILICATE HYDRATE, NEITHER THE INTERRELATION BETWEEN THE VARIOUS OBSERVED PARTICLE SHAPES NOR THEIR ROLE IN FORMATION OF THE FINAL MICROSTRUCTURE OF THE HARDENED PASTE HAS BEEN ESTABLISHED.

Doping as a Way To Protect Silicate Chains in Calcium Silicate Hydrates [PDF]

ACS Sustainable Chemistry & Engineering, 2018
A critical challenge in reducing anthropogenic impacts on the environment is to decrease the carbon footprint of the cement industry. A key concern in the search for more sustainable cement designs is the understanding and control of the depolymerization process that eventually determines the integrity of their silicate chains under mechanical ...

Structural models of random packing of spheres extended to bricks: Simulation of the nanoporous calcium silicate hydrates [PDF]

, 2009
Structure simulation algorithms of random packing of spheres and bricks have been developed. These algorithms were used to reproduce the nanostructure of the cementitious calcium silicate hydrates. The textural parameters (specific surface area, porosity,

Alleviating aluminium toxicity on an acid sulphate soils in Peninsular Malaysia with application of calcium silicate [PDF]

, 2015
In response to human population increase, the utilization of acid sulfate soils for rice cultivation is one option for increasing production. The main problems associated with such soils are their low pH values and their associated high content of ...

Calcium silicates synthesised from industrial residues with the ability for CO2 sequestration [PDF]

, 2014
This work explored several synthesis routes to obtain calcium silicates from different calcium-rich and silica-rich industrial residues. Larnite, wollastonite and calcium silicate chloride were successfully synthesised with moderate heat treatments below

Bioactive calcium silicate ceramics and coatings

Biomedicine & Pharmacotherapy, 2008
CaO-SiO2 based ceramics have been regarded as potential candidates for artificial bone due to their excellent bone bioactivity and biocompatibility. However, they cannot be used as implants under a heavy load because of their poor mechanical properties, in particular low fracture toughness.

A model for reactive porous transport during re-wetting of hardened concrete

, 2009
A mathematical model is developed that captures the transport of liquid water in hardened concrete, as well as the chemical reactions that occur between the imbibed water and the residual calcium silicate compounds residing in the porous concrete matrix.

Larnite powders and larnite/silica aerogel composites as effective agents for CO2 sequestration by carbonation [PDF]

, 2009
This paper presents the results of the carbonation reaction of two sample types: larnite (Ca2SiO4) powders and larnite/silica aerogel composites, the larnite acting as an active phase in a process of direct mineral carbonation.
