Blended cements are preferred to Ordinary Portland Cement (OPC) in construction industry due to costs and technological and environmental benefits associated with them. Prevalence of significant quantities of carbon dioxide ...

This paper reports study findings on the diffusivity of chloride ions in potential blended cement. The cement, abbreviated as PCDC, was made from blending ordinary Portland cement (OPC) with dried calcium carbide residue ...

The durability of cement-based structures majorly depends on their resistivity to the aggressive media in the construction environment. The most aggressive ions commonly encountered in construction environment are chloride ...

Cement structures are major capital investments globally. However, exposure of cement-based materials to aggressive media such as chloride- and sulphate-laden environments such as coastal areas affects their performance. ...

The potential for calcined clay, and in particular Limestone Calcined Clay Cement (LC3), to be used in concrete in Kenya was examined in this study. Locations of clay sources and existing mining infrastructure were examined ...

In the presence of significant quantities of carbon dioxide (CO2) and elevated temperatures in the atmosphere due to climate change, cement-based materials are susceptible to carbonation. Blended cements are more prone to ...

Due to rapid industrialization, urbanization, and surge in modern human activities, water contamination is a major threat to humanity globally. Contaminants ranging from organic compounds, dyes, to inorganic heavy metals ...

Huge amounts of wastewater in low and lower-middle-income countries is released into the environment in untreated forms due to an increase in anthropogenic activities and disposal in water bodies. Pollution in water ...

Ternary blended cements, such as limestone calcined clay cement (LC3), represent a type of strategic binder for the mitigation of environmental impacts associated with cement production. These are estimated to reduce CO2 ...

Cement is the world’s second-most consumed material and its production contributes substantially to global CO2 emissions. Replacing clinker with supplementary cementitious materials (SCMs), such as calcined clay, can lower ...
