| description | The report delves into the feasibility of employing mixed materials as alternative infill substances for caissons in land reclamation initiatives. The primary objective is to ascertain the suitability of these materials and predict the durability of caissons through a comprehensive investigation of chloride ingress and corrosion initiation on embedded steel reinforcements.
The methodology entails the Rapid Chloride Migration Test applied to local caisson concrete design mixes. This method assesses the chloride migration coefficient, providing insights into the rate of chloride ingress and the time required to reach critical chloride content on the reinforcement surface, initiating corrosion processes.
Key findings indicate that the migration coefficients fall within acceptable limits, affirming the suitability of the concrete design mix for caisson construction. The report underscores the significance of adopting a holistic approach, considering factors like chloride exposure, construction practices, and material characteristics when evaluating concrete durability.
Conclusions drawn from this study emphasize the need for a multifaceted perspective in concrete durability assessments. Advanced testing methods, modelling techniques, and predictive tools, including semi-probabilistic models, prove essential in offering more accurate service life predictions with acceptable levels of probability.
In terms of recommendations, the report underscores the importance of continued research and collaboration to unlock the full potential of mixed materials in enhancing concrete performance and durability. Efforts should concentrate on refining predictive tools, integrating emerging sustainable technologies, and disseminating knowledge to industry professionals. Through these initiatives, the widespread adoption of innovative and environmentally conscious practices can be fostered, ensuring the enduring resilience of concrete structures in an ever-evolving world. |
