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

Optimization of concrete design mixing artificial pozzolan based on orthogonal test [PDF]
In this paper, 42.5 sulfate aluminate cement mixing pozzolan was used to prepare fast early strength concrete to reduce the application costs by the equivalent of cement, Pozzolan content, sand ratio, water-cement ratio investigated by orthogonal experiment method to seek meet with the strength (%)

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

Study of Biofouling on Fly ash – Bottom ash (FABA) Media Subtract [PDF]
Biofouling is the process of attachment and growth of organisms on the surface of living and non-living objects. Biofouling is one of the biggest issues found on the surface of structures and unwanted organisms.

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