Sentence examples for between silicate chains and from inspiring English sources
Tobermorite is comprised of a CaO sheet sandwiched between silicate chains, and intermittent absent SiO4 tetrahedra creates a depolymerized silicate chain network.
Cong and Kirkpatrick [18, 19] suggest that CSH has a structure in which CSH contains repeating silicate chains and calcium polyhedra similar to tobermorite but with missing chain segments and silicate sites resulting in little long range periodicity.
Single silicate chains and associated interlayer Ca atoms are shown in (c).
A model dimer can also be derived from a clinotobermorite structure that had staggered silicate chains, and as with the orthotobermorite models, there are two alternative positions for the interlayer Ca atom that seem plausible.
The next structure that is needed is the other end-member, i.e. a structure that has infinite silicate chains and no interlayer Ca (Ca/Si = ), which will be referred to as T∞ (after Richardson & Groves, 1992 a ▸).
The name of the datablock for each structure starts with 'T' to denote 'tobermorite-based structure'; a number or '∞' that denotes the mean length of the silicate chains; and an underscore.
Because the interlayer water molecules prevent reconstruction of the bonds between the Caw and the silicate chains, the plasticity of the C-S-H gels is reduced significantly in the change from a dry state to a saturated state.
The structure consists of tobermorite slabs that have staggered silicate chains, no interlayer Ca atoms, and a layer spacing of 13.3 Å.
It is shown that there are no interlayer calcium ions when the silicate chains are of infinite length and that one is added for each tetrahedral 'bridging' site that is vacant.
The work of Murray et al. (Murray et al. 2010) suggests that electrostatic and bond forces at the atomic level of silicate chains as the main reason for the compressive strength of concrete and that its weak tensile strength is due to breaks in silicate chains at the atomic level.
11 Å clinotobermorite that has staggered silicate chains has not been observed in nature nor synthesized and so there is no structure available.
