Minimizing the use of ordinary portland cement (OPC) in concrete not only enhances cost-performance balance but also significantly reduces carbon emissions. In this research, we develop the technology of sectioned compaction self-assembly (S-CSA), which enables a nearly 50% reduction in OPC content without compromising strength. Through the sectioned operation, the processing system can be based on a relatively small press.
