3D-Printed Lightweight EPS Concrete
A composite aggregate model extends excess paste theory to mixtures containing sand and EPS particles and connects paste-layer thickness with rheology and printability.
Methods
X-Ray Tomography and 4D Imaging
Using non-destructive three-dimensional imaging to resolve internal material structure and follow its evolution during reactive and mechanical processes.
