THE USE OF POLYPROPYLENE FIBERS AGAINST PLASTIC SHRINKAGE CRACKING
Proceedings of International Structural Engineering and Construction, 2016 Plastic shrinkage cracking (PShC) occurs within a few hours after fresh concrete formed into the molds and it takes part on the surface of the concrete. When concrete formed into the molds, the aggregates settle because of the gravity and in contrast, water bleeds.

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing
Advanced Materials Technologies, EarlyView.Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability
Advanced Materials Technologies, EarlyView.ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

Research on influence of admixtures to the plastic shrinkage cracking of mortar
IOP Conference Series: Materials Science and Engineering, 2019 In this paper, the influence of admixture on plastic shrinkage cracking was studied. The results show that the plastic tensile strength increases while plastic shrinkage stress decreases as the content of air-entraining agent grows to 150×10-6 wt.%, and the anti-cracking index increases as a whole.
