TLDR
In this article, the authors evaluated the environmental impact of four cement manufacturing processes: (1) the production of traditional Portland cement, (2) blended cement (natural pozzolans), (3) cement where 100% of waste cement kiln dust is recycled into the kiln process, and (4) Portland cement produced when CKD is used to sequester a portion of the process related CO2 emissions.About:

Carbon dioxide equivalent (CO2-e) emissions: A comparison between geopolymer and OPC cement concrete
TL;DR: In this article, the authors present the results of comprehensive carbon footprint estimates for both geopolymer and OPC concrete, including energy expending activities associated with mining and transport of raw materials, manufacturing and concrete construction.
Journal ArticleDOI
Costs and carbon emissions for geopolymer pastes in comparison to ordinary portland cement
TL;DR: In this paper, the authors examined the lifecycle cost and carbon impacts of Ordinary Portland Cement (OPC) and geopolymers in an Australian context, with an identification of some key challenges for geopolymer development.
Journal ArticleDOI
Global strategies and potentials to curb CO2 emissions in cement industry
TL;DR: In this paper, three strategies of CO2 reduction including energy saving, carbon separation and storage as well as utilizing alternative materials in detail have been reviewed and the barriers against worldwide deployment of such strategies are identified and comprehensively described.
Journal ArticleDOI
An environmental evaluation of geopolymer based concrete production: reviewing current research trends
TL;DR: In this article, the authors carried out a detailed environmental evaluation of geopolymer concrete production using the Life Cycle Assessment methodology and found that the production of most standard types of OPC concrete has a slightly lower impact on global warming than standard Ordinary Portland Cement.
Journal ArticleDOI
A review of mineral carbonation technologies to sequester CO2
TL;DR: This work investigates the current advancement in the proposed MC technologies and the role they can play in decreasing the overall cost of this CO2 sequestration route and finds the value of the products seems central to render MC economically viable in the same way as conventional CCS seems profitable only when combined with EOR.

TL;DR: Using inorganic carbon measurements from an international survey effort in the 1990s and a tracer-based separation technique, the authors estimate a global oceanic anthropogenic carbon dioxide (CO2) sink for the period from 1800 to 1994 of 118 19 petagrams of carbon.
