Thermal activation of inert basaltic materials to create supplementary cementitious materials
Cement, 2023 The concrete industry faces an urgent need to identify new supplementary cementitious material (SCM) sources. One class of materials available in large volumes are basaltic materials, which are often stockpiled in landfills as a waste product from ...

Reutilization of Ceramic Waste as Supplementary Cementitious Material
, 2023 The production of Portland cement (PC) has the highest environmental impact among the different components of concrete. Also, although ceramic prod-ucts are consumed worldwide and constitute a significant fraction of construction and demolition waste, significant amounts of ceramic waste (BCW) are simply landfilled or used as road sub-bases.

Overview of clay as supplementary cementitious material [PDF]
5th Symposium on Doctoral Studies in Civil Engineering, 2019 Locally available materials, like clays, present a potential to meet the growing concrete demand and to produce more sustainable material. This paper reviews the behaviour of common clay minerals (kaolinite, illite and montmorillonite) giving an insight into the complexity of clay soils that usually appear as mixtures of minerals and impurities.
