Structural Survey, 1994
Briefly reviews the history of the calcium silicate brick and examines the manufacturing process involved. Details various qualities of the bricks, including durability, precision, thermal conductivity and some more general attributes, and advises on which conditions are most suited to the use of calcium silicate bricks.

Surface charges on calcium silicates and calcium silicate hydrates
Journal of Colloid and Interface Science, 1968Calcium ions effect a reversal of the sign of the electrokinetic potential on a- and ß-CaSiO3, a-Ca3Si2O7, ¿-Ca2SiO4, vitreous CaSiO3, xonotlite, and tobermorite in 0.01 N NaOH solution. Points of zero charge range from 1.10-3 to 4.10 M Ca2+. Differences of electrokinetic characteristics between different solids indicate that the surface layers are not

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 ...

Calcium Silicate Carbonation Products
Journal of the American Ceramic Society, 1995calcium silicates such as C 3 S, βT‐C 2 S, and γgM‐C 2 S were carbonated under saturated humidity at room temperature. Carbonation products were examined by DT‐TGA, gasphase mass spectroscopy, and XRD.

Strontium binding by calcium silicate hydrates
Journal of Colloid and Interface Science, 2006In the present study the binding of strontium with pure calcium silicate hydrates (C-S-H) has been investigated using batch-type experiments. Synthetic C-S-H phases with varying CaO:SiO(2) (C:S) mol ratios, relevant to non-degraded and degraded hardened cement paste, were prepared in the absence of alkalis (Na(I), K(I)) and in an alkali-rich artificial

Abstract Pastes of tricalcium silicate (C3S) and β-dicalcium silicate (C2S) 23 years old were studied by electron probe microanalysis. In both cases, regions consisting entirely or largely of calcium hydroxide and of CSH were distinguished on a scale of 2–50 μm. The regions high in CSH accounted for 75–80 percent of the whole in the C3S paste and

Aggregation of Calcium Silicate Hydrate Nanoplatelets
Langmuir, 2016We study the aggregation of calcium silicate hydrate nanoplatelets on a surface by means of Monte Carlo and molecular dynamics simulations at thermodynamic equilibrium. Calcium silicate hydrate (C-S-H) is the main component formed in cement and is responsible for the strength of the material.

The hydrated calcium silicates
Eos, Transactions American Geophysical Union, 1937The 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
