“…It can be observed from Figure 10 that the bleeding of the slurry gradually increases with time. The admixture of Li-B has a positive role in reducing the bleeding rate, which is consistent with the previous studies [36,37]. As the content of bentonite increases, the inhibitory effect of bentonite on bleeding evolution gradually weakens.…”

Acrylate is a popular polymer grouting material that has been widely used to control groundwater seepage. However, the vulnerability of acrylate slurry to dynamic water washout restricts its application in groundwater environments characterized by high flow velocity and water pressures. In this paper, lithium bentonite (Li-B) was used to modify the traditional magnesium acrylate (AC) grouting material. The influence of Li-B to AC ratios on the modified materials’ washout resistance was explored, and the modification mechanism was analyzed using X-ray diffraction (XRD), infrared spectroscopy (IR), and scanning electron microscopy (SEM). Finally, the anti-washout ability of the modified slurry was verified through engineering applications. Results revealed that LiB-AC grout had adjustable setting times (10.5 to 395.6 s), minimal bleeding (0.1%), higher viscosity (65 mPa·s) and expansibility (350%), stronger anti-water dispersibility (24 times that of pure AC slurry), higher mechanical strength (compressive strength is 0.386 MPa, tensile strength is 0.088 MPa), and better impermeability (2.23 × 10−8 m/s). The lithium bentonite was beneficial to the setting time, bleeding, viscosity, slurry retention rate, impermeability, and mechanical strength of the acrylate grout. However, it diminished the expansibility of the acrylate grout. At the optimal acrylate content (20%), the mechanical strength and impermeability of the LiB-AC grout were the highest. The better performance of LiB-AC grout was attributed to the formation of a more stable and dense interlaced spatial network structure after the modification by Li-B. The LiB-AC grout was used in the dynamic water grouting project of a metro shield tunnel segment and achieved better anti-washout performance than cement-water glass and pure AC slurry.

“…The mechanical properties of nanocomposites prepared from maleic anhydride based acrylated epoxy resin showed that the incorporation of 3 wt-% of nanoclay improved the flexural, tensile and hardness values of the composites compared to 1 and 5 wt-%(Mandal et al 2018). However, composites prepared from rosin derivatives as cross-linker can be considered as a fully biodegradable WPC with enhancement in UV stability, mechanical and other properties (Mandal et al 2018).…”

This work deals with the synthesis of biodegradable and UV resistant wood polymer composites (WPCs) via compression moulding technique. As outdoor applications become more widespread, durability becomes an issue. Ultraviolet exposure can lead to photodegradation, which results in a change in appearance and mechanical properties. In this study, we examined the performance of WPCs after UV exposure and microbial attack. The rate of degradation was found to decrease by the addition of a higher percentage of rosin derivatives. The bacterial growth on the samples and morphological features of the bacterialdegraded samples were investigated by UV spectrophotometry and Scanning Electron Microscope (SEM) study, respectively. The UV-degraded samples were also analysed by Fourier Transform Infrared (FTIR) spectroscopy and SEM study. It was observed that with the incorporation of 40 wt-% of divinylacrylicpimaric acid (DAPA) significantly improved the UV stability, mechanical, thermal and other physical properties of the WPCs.
