Temperature is one of the main factors affecting the properties of polyurethane foams, and
there are large differences in the mechanical properties of polyurethane foams at different …

This paper discusses methods of using biomass from the agriculture, forestry, food and
aquaculture industries as potential raw materials for bio-polyols and as fillers in the …

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 …

The split grouting method can play a very good anti-seepage and reinforcement effect for
some soil dykes that are not compacted or have hidden dangers such as leakage channels …

Grouting is the most commonly used method to control water inrush in underground
engineering. Traditional cement-based materials are easy to dilute and hard to coagulate …

The mechanical properties of the roadbed rehabilitation polyurethane (PU) grouting
materials subjected to different chemical corrosion are the theoretical basis for evaluating …

Deep coal mining requires grouting reinforcement materials with adjustable setting time,
high early strength and toughness. Sulphoaluminate cement-based grouting materials …

Weight plays a significant role in the automotive and aerospace fields due to the demand of
lightweight material structures. A lighter body in weight (BIW) and in structure can reduce …

The non-aqueous reactive foamed polyurethane is widely used in engineering. We have
observed the micromorphology of the non-aqueous reactive foamed polyurethane by field …

Two-component polyurethane has been widely used in various types of engineering. In this
work, polyurethane samples with different foaming ratios were obtained by adjusting the …
