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.

Potential of Construction and Demolished Wastes as Pozzolana

Procedia Technology, 2016
AbstractThe construction and demolition (C&D) wastes constitute 25% of the solid waste generation in India. A large proportion of these wastes are disposed off as landfill leading to severe social and environmental problems. Environmental considerations are pushing the industry towards more sustainable practices which leads less energy intensive ...

Effect of natural pozzolana, pozzolanic sand, and basalt on thermal and mechanical properties of green concrete

Building Engineering
Green concrete, also known as sustainable concrete, is a building material that aims to reduce environmental impact by using natural, recycled, or sustainable materials in its production. One way to achieve sustainability in concrete is to replace cement
