Clays for Low-Carbon Cements: Overview, Progress, and Challenges. [PDF]
Glob ChallThis review provides a critical overview of recent developments of activated clays to function as artificial pozzolans. After a thorough description of the clays that yield good pozzolanic performances, selected examples are given on thermal and mechanical activations. Chiefly, general correlations are extracted from reported data despite its scattered

An approach for predicting the stability of vertical cuts in cohesionless soils above the water table [PDF]
, 2013 Temporary vertical excavations in cohesionless (granular soils) pose a problem for conventional ‘two-phase’ soil mechanics theory since non-zero collapse height is not predicted using the classical ‘dry/saturated’ shear strength criterion, given that ...

Effect of the Fineness of Artificial Pozzolana (Sarooj) on the Properties of Lime-Pozzolana Mixes
Sultan Qaboos University Journal for Science, 2002 Strength development of lime-pozzolana mortars is affected by the fineness of the pozzolan. This paper examines the effect of the fineness of artificial pozzolana on the strength development of lime-pozzolana mixtures. An artificial pozzolana produced by
