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

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