The effect of the soft and hard polyurethane (PU) segments caused by the hydrogen link in
phase-separation kinetics was studied to investigate the morphological annealing of PU and …

The impact resistance of Polyurethane (PU)-based polymer concrete was investigated using
U-shaped specimens tested on a newly designed drop-weight impact test device. The PU …

This paper presents an extensive experimental study of a low-cost, high-performance
seismic isolator comprising a deformable sphere rolling on concrete surfaces. Polyurethane …

Cement-based grouting materials have high compressive strengths, but they are brittle. The
low strain burden limits their rehabilitation application in the high compressive strain …

Predicting the properties of complex polymeric materials based on monomer chemistry
requires modeling physical interactions that bridge molecular, interchain, microstructure …

Normal concrete-polyurethane grout (NC-PUG) composite U-shaped and beam specimens
were developed in this study to evaluate the capability and efficacy of PU grouting material …

Experimental investigation was conducted using concrete specimens to assess the
effectiveness of bio-based polyurethane (PU) coating synthesized from palm kernel oil in …

As an excellent anti-blast material, polyurea (PU) has been widely used in the reinforcement
of masonry walls, RC structures, steel structures, and composite materials. The advances in …

We conducted large-scale molecular dynamics (MD) simulations of shock wave propagation
and spallation in amorphous polyurethane and polyurea. First, we computed the shock …

Polyurethane (PU) composite is increasingly used as a repair material for civil engineering
infrastructure, including runway, road pavement, and buildings. Evaluation of polyurethane …
