Research on the improvement of underwater workability of cement paste by composite polymers

Case Studies in Construction Materials
The underwater workability of cement paste is essential for the application of non-dispersive underwater materials. However, the coordination of fluidity and flocculation remains challenging. While superplasticizers can enhance the fluidity of underwater

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

Advanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Study of the Dielectric Characteristics of Cement Paste

Materials Science Forum, 1998
The characterization of the microstructure of cementitious materials by means of Impedance Spectroscopy (IS) is attracting an increasing interest. This is due not only to the importance of the cement cover on steel corrosion, but because of the possibility of characterise aspects like hydration degree of cement or water content.

Mild Focal Cooling Decouples Dendrites to Reconfigure Cortical Output

Advanced Science, EarlyView.
Mild cooling of the cortical surface selectively modulates apical dendritic excitability, plasticity, and somato‐dendritic coupling, while uncoupling these effects from basal dendrites, and reshapes apical‐driven responses in barrel cortex during whisker touch.
