Carbonation of cement-based materials: Challenges and opportunities

Thursday, 2 June 2016

A researcher from Lyles School of Civil Engineering, Purdue University, summarises the existing knowledge regarding the carbonation of cement-based materials and identified the areas which require further investigations.

Available studies regarding the carbonation test scenarios, influences of supplementary cementitious materials (SCMs) on carbonation resistance, and effects of carbonation on the properties of cement-based materials are reviewed here.

Newly developed carbonate binders

In addition to ordinary portland cement (OPC) based materials, the article has reviewed the performances of sulfoaluminate belite and alkali activated materials (AAM) while subjected to carbonations. Some very recent topics such as the potential of CO2 storage in concrete and the newly developed carbonate binders are also discussed.

The study is published in: Construction and Building Materials, Volume 120, 1 September 2016, Pages 558–570
