This paper offers a thorough unfolding of the many contributions that water‐soluble polymers (WSPs) play in cementitious composites. The several forms of WSPs—natural, semi‐synthetic, and artificial—are examined, and their methods of action in cementitious composites are investigated. The topics of binding, association, adhesion, complexation, and bridge creation are covered in the literature. The effects of WSPs on the microstructure, freshness, mechanical properties, and durability of cement‐based goods are also investigated in this review. The advantages and disadvantages of utilizing WSPs in cement‐based products are also discussed. Following a detailed analysis of the most significant findings, recommendations are made for both academic and practical research areas and applications. This study provides useful information for both experts and novices by elucidating the multi‐applications of WSPs in cementitious materials.

“…Among them, a mold bag is one of the geosynthetics, which is a double-layer bag-like fabric woven by a machine from high-strength chemical fiber filaments with engineering characteristics of permeability, air permeability, and impermeability to slurry [19]. Therefore, the mold bag concrete relies on this characteristic of the mold bag, relying on self-weight and the pressure of the grout pump to discharge excess water from the pores of the mold bag, which reduces the water-cement ratio and achieves the design strength after solidification [20,21]. In China, mold bag concrete is widely used in canal and slope protection engineering because of its unique advantages.…”

To cater to the problems of a poor working environment, a large amount of rebound, and the high energy consumption of sprayed concrete in tunnel engineering, this paper proposes a new support scheme with a steel corrugated plate combined with mold bag concrete. Analytical solutions of stresses for steel corrugated plate and mold bag concrete were deduced based on the thin-walled cylinder, and then their strength safety factors were presented. Subsequently, a series of numerical simulations were conducted to investigate the mechanical performance of the third ring of the main structure based on the ‘load-structure’ 3D model. The numerical results were verified using the classical theoretical analysis and the proposed model, and then parametric studies were performed through the numerical method. Finally, field tests in a circular shaft were carried out to verify the feasibility of the structure and process and the engineering effect. The results show that the combination of steel corrugated plate and mold bag concrete is feasible and can realize rapid support technology for underground engineering, which provides a new idea for the supporting technology of underground engineering such as tunnels.

In order to explore the frost resistance durability of basalt fiber reinforced concrete (BFRC), the freeze-thaw cycle tests of BFRC with different fiber contents were carried out from the microscopic point of view, and the macro-morphological deterioration characteristics and micro-morphological characteristics of BFRC with different freeze-thaw cycles were analyzed. By testing the hole structure parameters of BFRC with different freeze-thaw cycles, the effects of gas content, average bubble chord length, specific surface area, and bubble spacing coefficient on the frost resistance of BFRC were studied. The results show that: With the increase of fiber content, the damage degree of concrete specimens weakens, and the proportion of harmful pores in the pore size distribution increases significantly; It decreases with the increase of bubble spacing coefficient; The addition of basalt fiber can effectively inhibit the development of cracks and reduce the probability of large pores in the process of concrete freeze-thaw damage, thereby improving the frost resistance of concrete. Therefore, for the northern region, the research on the frost resistance of BFRC is very necessary and of great significance.
