| Abstract: | The effect of nano-materials on strengthening the recycled concrete aggregate interface was studied by means of XRD and SEM. Based upon experimental works, the recycled aggregate interface structure was improved by nano SiO2, nano CaCO3 and Na2SiO3. That process can fill up some pores and cracks, resulting in an improved interfacial zone around recycled aggregate and a higher strength. |
