Effect of Pozzolana and Lime on Expansive Soil Properties

FES Journal of Engineering Sciences, 2021
This study investigates the effect of pozzolana and quick lime as stabilizer materials on expansive soil properties. Disturbed soil sample was collected from Al-Qadarif city in east of Sudan. The basic properties, swelling and strength of the soil were measured. The soil shows very weak strength and very high swelling potential.

The influence of natural pozzolana mineralogical composition in the properties of blended cement

Materiales de Construccion, 2002
The pozzolana activity is the main property of the active additions but, in order to select them, we have to consider - between other factors- its mineralogical composition with a great influence, not only in the active component, but also in other ...

Development of Ambient‐Cured Geopolymer Concrete: Investigating Bottom Ash as a Sustainable Alternative to Natural River Sand

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Portland cement production is a major contributor to global CO2 emissions, and the scarcity of natural river sand limits conventional concrete production. Despite increasing interest in geopolymer concrete (GPC), studies on sustainable, low‐temperature cured GPC using industrial by‐products as fine aggregate replacements are limited.

The Apparent Thermal Conductivity of Pozzolana Concrete

Physics Procedia, 2011
AbstractThe recent development of some lightweight construction materials, such as light concrete, can play an important role as an insulator, while maintaining sufficient levels of mechanical performance. The quality of insulation to provide depends on the climate, the exposure of the walls and also the materials used in the construction.
