Abstract: Polyurethane has been widely used as new chemical grouting material. Expansion characteristics caused by chemical reactions make polymer grout different from other types of grout. To throw light on the diffusion process ...

Abstract: An experimental program was conducted to investigate the application of headed glass fiber-reinforced polymer (GFRP) ribbed bars at the barrier wall-deck anchorage. Six full-scale barrier models of 1,200 mm in length were ...

Abstract: Polyurethane grouting can be used for antiseepage and reinforcement in underground construction. Understanding the diffusion characteristics of polyurethane grout is critical for good grouting design. However, the influence ...

Abstract: This paper studies the four-quadrant homologous characteristic and analyzes the gas–liquid two-phase flow head degradation of ACP100 reactor coolant pump. The theoretical basis and the operating conditions of the pump's ...

Abstract: Low exothermic polyurethane grouting material, as a new type of material, is used for road reinforcement and repair engineering in frozen earth areas. This study investigates the mechanical properties of this grouting ...

Abstract: Highenergy synchrotron radiation has proven to be a powerful technique for investigating fundamental deformation processes for various materials, particularly metals and alloys. In this study, highenergy synchrotron Xray ...

Abstract: The complicated pore-throat structure of unconventional resource formations such as tight sandstones influences petroleum accumulation and even exploitation, because the pore-throat structure is difficult to mark. A ...
