This paper discusses the shell structure reinforced composite based silicate aggregate core. The interface between the shell and the core nakes them to form a whole by the hydration product overlap. The performances of the SAAC aggregate and the FAAC aggregate are compared, and it is shown that the shell structure could improve the cylinder compressive strength (CCS) of the artificial silicate aggregate. The CCS of the SAAC aggregate is enhanced by 49.72%-80.50%, and the CCS of the FAAC aggregate is enhanced by 15.30%-25.74% with the shell structure. The best weight ratio of the shell and the core is 1:25, with shell thickness of 68.09 μm. The CCS of the artificial silicate aggregate with the shell structure is enhanced by about 25% as compared with that without the shell structure. Compared the silicate aggregate concrete with the ordinary concrete in the same level mortar and volume of the aggregate, it is shown that the compressive strength of the silicate aggregate concrete is 6.38% lower than the ordinary concretes, and the apparent density of the silicate aggregate concrete is 20.74% lower than the ordinary concrete., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=nzqimwV+rW7syeZCIlAMBA==, pdfFileSize=3404135, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
