Improvement mechanism of recycled concrete using C-S-H type accelerator and modifying recycled aggregate by carbonation technology

Acta Polytechnica CTU Proceedings, 2022
In Japan, there is concern that concrete blocks due to demolition will increase with the renewal of concrete structures. Although it has been used for roadbed materials as recycling, in recent years, aggregates are removed from the concrete mass by ...
