Research Progress of Eco-Friendly Portland Cement Porous Concrete: A Review

Abstract

With the great impetus of energy conservation and emission reduction policies in various countries, the proposal of concepts such as “Sponge City” and “Eco-City”, and the emphasis on restoration and governance of ecological environment day by day, portland cement porous concrete (PCPC), as a novel building material, has attracted more and more attention from scientific researchers and engineers. PCPC possesses the peculiar pore structure, which owns numerous functions like river embankment protection, vegetation greening as well as air-cleaning, and has been of wide application in different engineering fields. This paper reviews the salient properties of PCPC, detailedly expounds the research progress of domestic and foreign literature about this subject in the past ten years (2010–2020), conducts the statistical analysis of the distribution rule of its major properties around the world, combines with the engineering application to summarize the excellent properties of PCPC, and makes a forecast of future research direction.
