Particle Motion in Fluid: Analytical and Numerical Study

Applied Rheology, 2016
Particle motion in fluid is discussed for one-particle systems as well as for dense suspensions, such as cementitious materials. The difference in large particle motion between larger particles and behaviour of fines (< 125 μm) is explained, motion of ...

Adhesive cements and cementation.

Journal of the California Dental Association, 1993
Luting cements are a critical, but weak, link between fixed prostheses and their supporting tooth structures. Luting cements have relatively poor physical properties compared to bulk restorative filling materials, but they must fulfill an additional series of requirements such as low film thickness.

CEMENT TLA

, 2019
Da bi se na nekoj podlozi nešto sagradilo potrebno je da podloga ima određena svojstva primjerena gradnji. Danas se za pripremu neadekvatne podloge za gradnju koriste dva načina. Jedan podrazumijeva da se podloga za izgradnju u potpunosti promjeni, a drugi je da se postojećoj podlozi poboljšaju svojstva.

Workability, compressive strength, and efflorescence characteristics of one-part mix alkali-activated circulating fluidised bed combustion fly ash-based mortars

Cement
In this study, one-part alkali-activated mortars are formulated using circulating fluidised bed combustion (CFBC) fly ash, derived from lignite (brown coal) combustion, as the precursor, and sodium hydroxide (NaOH) and sodium metasilicate (Na2SiO3) as ...
