Atmospheric CO2 is a major cause of reinforcement corrosion in bridges, buildings, wharves, and other concrete infrastructure in Indonesia, Australia, United States, United Kingdom and most other countries. The increase in CO2 levels associated with global warming will increase the likelihood of carbonation-induced corrosion. Moreover, temperature rises will increase corrosion rates. Clearly, the impact of climate change on existing (old) and new infrastructure is considerable, as corrosion damage is disruptive to society and costly to repair. In particular, many existing concrete structures, for which the design has not taken into account the effect of changing climate, are likely to suffer from more decreased durability as a consequence of climate change which followed by the potential collapse. To minimize the failure and increase the life span of the infrastructure, the development of a new class of more sustainable cement-based materials that can tackle climate change is needed. The PRO-LCC project will bring the ITS researchers to offer the comprehensive work into the evaluation of green concrete structure which maintain the tensile ductility characteristics, but which also incorporate sustainability considerations in the design of these materials for infrastructure applications. More importantly, taking the precautionary principle, simulations may inform the necessary extent of change in maintenance required to maintain the safety, serviceability and durability given the likely climate change scenarios. PRO-LCC incorporate industrial waste streams while not sacrificing critical material properties. This project describes various results of an initial attempt at creating Green concrete. The sustainable material design integrates microstructure tailoring with life cycle analysis to proof the sustainable building. The framework of PRO-LCC development is described. Some preliminary experimental results of the effect of cement substitution and fibre substitution with industrial by-products on the mechanical properties are reported. It is demonstrated that the concept of PRO-LCC for green urban development is feasible, although an extensive amount of research remains ahead. This project is also consistent with the implementation of sustainable development goals (SDGs), to provide sustainable infrastructure and environment which have highlighted the importance of continued support for infrastructure development to sustain inclusive growth in Indonesia. One of the milestones of this project is to clarify into the international publication (Q2) under a concept of designing PRO-LCC to improve the sustainability of urban development indexed by Scopus or Web of Science. This target also not limited to joining the international conference and publish Intellectual property right.
