Special Issue Information

Dear Colleagues,

This Special Issue focuses on the innovative application and research of polymers and functional additives in construction materials. As modern architecture places increasing demands on performance and sustainability, enhancing the mechanical properties, durability, and multifunctionality of traditional building materials through polymeric materials and functional additives has become a vital direction for the industry. This Special Issue aims to compile the latest scientific achievements and technological advancements in the field. These developments not only significantly improve the adaptability and service life of construction materials in diverse environments, but also provide effective solutions for promoting green buildings and reducing life-cycle maintenance costs. We hope that this Special Issue will serve as a platform for an in-depth exchange between academia and industry, fostering the innovative development of construction materials toward high performance, multifunctionality, and environmental friendliness.

Styrene butadiene rubber (SBR) is a commonly used polymer modifier that can improve the mechanical properties and durability of cement mortar. However, the effects of different emulsifier types on cement hydration behavior and structural evolution still need to be systematically studied. To clarify the differences among anionic, cationic, and nonionic SBR emulsions on mortar performance, three types of SBR emulsion were selected in this study. Setting time, chemically bound water, mechanical properties, chloride ion diffusion, freeze–thaw cycles, and microstructure were tested to evaluate the effects of different types and dosages on cement mortar. The results show that all three types of SBR emulsion prolong the setting time of cement paste and reduce the early hydration degree. The cationic SBR emulsion shows a more obvious effect. At 28 d, the compressive strength of mortar with 10% cationic SBR emulsion increases from 38.5 MPa to 41.2 MPa, and the flexural strength also increases. In terms of impermeability, the chloride ion diffusion coefficient decreases from 7.47 × 10−12 m2/s to 5.12 × 10−12 m2/s after adding 10% cationic SBR emulsion. After 100 freeze–thaw cycles, the compressive strength loss of ordinary mortar is 16%, while it decreases to 7.2% with 15% cationic SBR emulsion, and the mass loss is also reduced. Microstructural analysis shows that the modified mortar has a denser internal structure, improved interfacial continuity, and reduced crack development after freeze–thaw cycles. Full article

To address the challenges of decarbonization in the global transportation sector and disposal of waste tires, warm asphalt rubber (WAR) with low viscosity and high performance was prepared. In particular, the preparation and rheological behavior of WAR incorporating composite warm mix systems at relatively high crumb rubber contents have not been thoroughly documented. In this study, WAR prepared under such conditions was systematically examined. A five-factor, three-level segmented orthogonal experimental design (OED) was employed to investigate the effects of preparation parameters on hot mix asphalt rubber (AR) properties. Based on the optimized AR formulation, a composite warm mix system combining Ultra-Warm Mix additive (UWM) and Sasobit was developed, and control groups containing 5% UWM only and 1.5% Sasobit only were prepared for comparison. Conventional physical tests together with rheological characterization, including Dynamic Shear Rheometer (DSR), Multiple Stress Creep Recovery (MSCR), and Bending Beam Rheometer (BBR) tests, were conducted to evaluate the high- and low-temperature performance of WAR. Results show that the optimal preparation process consisted of aromatic oil content 5%, crumb rubber content 30%, shear temperature 220 °C, shear time 120 min, and reaction time 90 min. The composite warm mix system notably enhanced WAR performance, with the WAR-5U1.5S group exhibiting the most balanced properties. A marked reduction in rotational viscosity was achieved while maintaining a stable softening point, and satisfactory ductility and elastic recovery were also retained. DSR and MSCR tests confirmed improved high-temperature deformation resistance, an increase in percent recovery R, and a decrease in non-recoverable creep compliance Jnr. BBR test further verified that the composite system maintained good low-temperature cracking resistance, meeting all specification requirements. Overall, these results indicate that, compared with the optimized AR, WAR can reduce mixing viscosity without sacrificing rutting or cracking performance, while alleviating the limitations observed for single warm mix additives. This study provides essential technical support for promoting WAR that integrates low-carbon construction with superior pavement performance. Full article
