...Juan He; Dongdong Yuan; Shanhansu Xu; Junhong He; Yonghua Wu A large amount of construction waste could be reused if recycled aggregate ( RA ) is used to prepare pervious planting concrete ( PPC ). This would reduce the consumption of natural resources and environmental burdens, in line...

...% replacements of natural aggregate (NA). The PLA was used a replacement of 5% of conventional Portland cement and also in a mix with 5% addition of PLA. The recycled aggregate concretes were tested for workability and compressive strength. The results showed that when 80% of NA was replaced with recycled...

..., particularly recycled aggregate (RA). Due to the presence of adhered mortar, RA has more complex structural characteristics than natural aggregate (NA). It is therefore difficult to model RA, especially the distributions of irregular angles and sharp corners. A new modelling method based on the compression...
