Performance of self-compacting concrete incorporating palm oil fuel ash and egg shell powder as partial cement replacement

Self-compacting concrete (SCC), is an innovative concrete that uses less aggregates, but high content of cement compared to normal concrete. It is able to flow by itself and does not require compaction. Therefore, raw materials and natural resources are required in large quantities for SCC prod...

Furthermore, based on the results, it was observed that the combined utilization of POFA and ESP enhanced the pozzolanic activity, thus, developing additional calcium silicate hydride (C-S-H) gels which are responsible for the gain in strength. The combined utilization of POFA and ESP as a cement replacement in SCC had good effect on the compressive and tensile strengths.
