The Complexation of Lanthanides by Azo-B-Diketones Stability Constants
(
Qatar University
, 1982 , Article)
The stability constants of the complexes between the trivalent lanthanide series of cations and series of azo-B-diketone ligands are reported. The measurements were conducted at 30°C and zero ionic strength (free KN03), ...
Studies on Soil Cements: 1 - Role of Hydrated Lime and Dolomitic Monohydrate in Montmorillonite Stabilization
(
Qatar University
, 1982 , Article)
Montmorillonite clay was stabilized by either hydrated lime or the dolomitic monohydrate (Ca(OH)2. MgO) during suspension hydration at 25 and 60°C for 45 days. The distinct phases produced from the hydration of each ...
Stability Constants of Lanthanide Complexes with some Structurally Related Organic Ligands
(
Qatar University
, 1982 , Article)
The stability constants of the complexes formed between trivalent lanthanide ions and related carboxyphenylhydrazo-B-diketones ligands are repoted, at 30 °C and at constant ionic strength (0.1 KN03), in 75 % dioxane-water. ...
Studies on Soil Cements : 2 — Physicochemical Properties of the Hardened Soil Cement Pastes.
(
Qatar University
, 1982 , Article)
Various hardened soil-cement pastes were prepared from dry mixtures of montmorillonite clay and portland cement clinker by using different W/C ratios of 0.20, 40, 0.60 and 0.80 and cured in air for various ages. Compressive ...
