Aggregate dissolution kinetics

Magazine of Concrete Research, 2023
The alkali–silica reaction (ASR) starts with the dissolution of silica in alkali-reactive aggregates. Besides the thermodynamic basics of silica dissolution, kinetic data are needed to model ASR in order to describe the temporal course of the reaction. Although the dissolution kinetics of silica has been investigated frequently, data for concrete-like

Dissolution Kinetics of Primary Chalcopyrite Ore in Hypochlorite Solution

open access: yesMinerals Engineering, 2006
Dissolution kinetics of primary chalcopyrite ore from Artvin-Murgul, Turkey has been studied in hypochlorite solution. The dissolution kinetics was found to be controlled by diffusion through the product layer as the rate-determining step. The activation

Dissolution Kinetics of Phenylbutazone

Journal of Pharmaceutical Sciences, 1981
This study investigated the possible effects of simultaneous, noninstantaneous, reversible chemical ionization of carbon acids on the dissolution of a typical pharmaceutical carbon acid, phenylbutazone, and its deutero analog. The dissolution rate versus pH profile for phenylbutazone was consistent with phenylbutazone acting as if it were an acid where

Dissolution Kinetics of Nanocrystals

ChemPhysChem, 2013
A simple series of test-tube experiments is all it takes to quantify a largely neglected nano-effect responsible for a dramatic increase-by orders of magnitude-in the surface-area-normalized rate of dissolution of nanocrystals. Though the observed variation in this specific rate as a function of size is unprecedented, the effect may be rationalized in ...

Dissolution Kinetics of Hydroxyapatite

Nature, 1966
THE formation of white spots, which is the first clinical sign of dental caries, is a consequence of sub-surface decalcification1. The carious process therefore involves dissolution of the crystallites—predominantly hydroxyapatite—which constitute the bulk (about 95 per cent by weight) of human dental enamel2.

Kinetics of Dissolution of β-Tricalcium Phosphate

Journal of Colloid and Interface Science, 1997
The rate of dissolution of beta-tricalcium phosphate (beta-Ca3 (PO4 )2 ; beta-TCP) has been measured in the solution system Ca(OH)2 -H3 PO4 -NaOH-HNO3 -H2 O. The effects of different parameters such as pH, temperature, time, and saturation have been investigated.
