    the study of recycled concrete micro-structure and their durability can complete and improve this study. Such a study can extend the usage range of recycled aggregates-based concrete in civil engineering. · the recycled aggregate. The use of recycled aggregate generally increases the drying shrinkage creep & porosity to water & decreases the compression strength of concrete compared to that of natural aggregate concrete. It is nearly 10-30% as per replacement of aggregate. Recycling reduces the cost (LCC) by about 34-41% & CO 2 emission (LCCO 2In Singapore,
