As a new type of chemical grouting material, polymers have been widely used in fractured
rock masses, but the understanding of the diffusion characteristics of polymers still needs to …

A key problem in the modeling of polyurethane (PU) foaming is the determination of relevant
physical parameters for the viscosity, the gas expansion, and the curing rate. Indeed, it is …

Polyurethane grouting is an important technical solution used for seepage prevention and
mechanical reinforcement of fractured rock. Various components of polyurethane grout …

Abstract A three-dimensional (3D) numerical model for polymer grouting in rock mass
fractures based on reaction kinetics theory is established in this article. The model integrates …

In the present paper, the foaming process of biosourced thermoset foams was considered at
the lab scale with the aim of creating a numerical model able to simulate, for the first time …

Polyurethane foams are widely used materials often chosen for their useful characteristics
such as low thermal conductivity, ease of application, and high strength‐to‐weight ratios …

Different formulations of foaming polyurethane grout offer controlled expansion rates. This is
crucial for precision in filling voids without exerting excessive pressure on surrounding …

We describe experiments designed to inform computational models of the dynamic filling
process of chemically blown, polyurethane foams, especially subgrid models to predict …
