Cementitious materials exhibit shrinkage strain on drying, leading easily to crack formation when internally or externally restrained. It is known that cements with a slow strength gain show higher crack resistance under external drying. The ring shrinkage test can be considered an accelerated method for cracking tendency due to existing historical

1. Introduction. The building sector consumes approximately 40% of global energy. Specifically, residential buildings account for 27% of the total energy consumption and 17% of the total building CO 2 [1].Much of the energy consumption and CO 2 emissions of residential buildings are used to maintain indoor thermal comfort through heating and
