Effect of the Fineness of Artificial Pozzolana (Sarooj) on the Properties of Lime-Pozzolana Mixes

open access: yesSultan 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

Development of artificial hydraulic lime [PDF]

open access: yesНанотехнологии в строительстве
Introduction. Lime mortars used for the restoration of historical buildings are characterized by low resistance during operation. The durability of lime solutions can be increased by using hydraulic lime as a binder.

Barley Straw Ash: Pozzolanic Activity and Comparison with other Natural and Artificial Pozzolans from México

open access: yesBioResources, 2015
The construction industry is one of the largest and most active growth sectors worldwide. It presents an important environmental impact, and one way to reduce the impact of the construction activity is to substitute pozzolanic materials for ordinary Portland cement.

Performance of silicic pozzolans and Portland cements in their behavior in front of gypsum attack as determined by ASTM C 452-68

open access: yesMateriales de Construccion, 2013
For this study, ASTM C 452-68 testing was conducted for two years on 54 POZC-silica fume (SF) or diatomites (D and N) (=Z pozzolans), were tested for 2 years, by ASTM C 452-68 method, having determined to their specimens their Vcl(=ΔL(%)/day) .

Is the clay "exchange capacity" concept wholly applicable to pozzolans?

open access: yesMateriales de Construccion, 2004
One of the most characteristic properties of clays is their "cation exchange capacity", otherwise known as their "exchange capacity ". The research reported in this article shows that for various reasons some natural and artificial pozzolans exhibit this

Clays for Low‐Carbon Cements: Overview, Progress, and Challenges

open access: yesGlobal Challenges, Volume 10, Issue 1, January 2026.
This 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
