These combinations enable the fine-tuning of mechanical, thermal, and chemical properties, creating materials tailored for specific functional and structural roles. Recent research on geopolymer-based composites has shown that the integration of reinforcements not only improves crack resistance and toughness but also expands the range of applications beyond traditional construction.

This study employs solutions of varying concentrations to treat the surface of small particle size rubber (SPSR) through an immersion method, aiming to reduce its hydrophobicity and enhance the strength of 3D printed small particle size rubber concrete (3DP-SPSRC). The mechanical properties of 3DP-SPSRC modified with three types of solutions are tested and verified that all three solutions can improve the mechanical properties of the concrete to varying degrees. Among them, the concentrations of the three solutions that yield the best modification effects are as follows: 15 % sodium hydroxide solution (NaOH) for modification, 10 % sulfuric acid solution (H<sub>2</sub>SO<sub>4</sub>) for modification, and 5 % potassium permanganate solution (KMnO<sub>4</sub>) for modification. The improvement range of compressive and flexural strength of 3DP-SPSRC by them is between 4.3 % and 35.93 %. Among the three solutions evaluated, 5 % KMnO<sub>4</sub> treatment demonstrates the most significant improvement in mechanical strength. Through comparative analysis of the activation index and contact angle measurements of SPSR before and after modification, it is evident that both parameters exhibit a marked reduction post-treatment, which indicates that the modification processes employed effectively enhance the hydrophilic properties of the rubber. Notably, 5 % KMnO<sub>4</sub> modified rubber displays superior hydrophilicity compared to the other treatment conditions. Based on SEM, the micro - morphology of the modified rubber is observed and analyzed. The workability and extrudability tests demonstrate that the modified 3DP-SPSRC could be well-suited for the self-developed 3D concrete printer, and the interlayer bond strength is significantly increased by 46.63 %.

Geosynthetic reinforcement improve the pavement performance by providing lateral restraint and tensioned membrane action. For pavement application, geogrids and geocells are widely used. On the other hand, the construction and demolition (C&D) waste generation is increasing owing to rapid urbanization posing significant environmental and logistic challenges. To address the issues related to C&D waste, numerous research has been conducted in the past to characterize recycled concrete aggregate (RCA) for its use in granular layers of pavements through mechanical and additive stabilization techniques. However, these methods have limitations, including the need for specialized equipment, labour-intensive processes, and curing period. Owing to the limited studies on the performance of RCA in conjunction with geosynthetic reinforcement in granular sub-base (GSB) application, this study evaluates the performance of RCA in GSB application with and without geosynthetic reinforcement and compare its performance with conventional aggregates (CA). Prototype pavement sections were constructed under unreinforced (UR), geogrid reinforced (CGG), geocell reinforced (CGC), and combination of geocell & basal geogrid-reinforced (CGG + CGC) conditions. Through repeated load tests, displacement of the pavement section, vertical pressure at the subgrade level, and strain along the reinforcement are monitored. Results showed that RCA performed comparable to CA, supporting its use in GSB application and promoting sustainable practices. Geosynthetic reinforced pavements exhibited reduced plastic displacement by a factor of 0.13 to 0.41 compared to UR sections. The CGG + CGC sections achieved the highest traffic benefit ratio (TBR) of 4.55 with CA and 7.25 with RCA. Additionally, geosynthetic reinforced sections showed reduced residual pressure by 0.14 to 0.39 times compared to UR sections. Strain analysis indicated superior load distribution in CGG + CGC sections over sections with CGC alone.
