The　effect　of　lightweight　aggregate　(LWA)　type　on　the　early-age　autogenous　shrinkage　of　lightweight　aggregate　concrete　(LWAC)　was　investigated　based　on　a　corrugated　tube　testing　method.　The　study　reveals　that　the　early-age　autogenous　shrinkage　includes　liquid　phase,　skeleton-formational　phase　and　hardening　phase,　and　is　also　affected　by　cylinder　compression　strength　and　water　absorption　rate　of　LWA.　For　the　summation　of　the　early-age　autogenous　shrinkage　of　skeleton-formational　phase　and　hardening　phase　after　time-zero,　which　are　concerned　with　the　development　of　stress　in　concrete　and　the　resulting　cracking,　as　long　as　the　net　water　cement　ratio　or　total　water　cement　ratio　is　kept　the　same,　the　LWAC　with　LWA　of　higher　water　absorption　rate　and　lower　cylinder　compression　strength　shows　larger　early-age　autogenous　shrinkage　than　the　LWAC　with　LWA　of　lower　water　absorption　rate　and　higher　cylinder　compression　strength　when　the　LWA　was　prewetted.　©　2016　Elsevier　Ltd.
