Sui Dynasty Lime Mortar Construction Technology

Timeline

1. 581–585Guanzhong Plain · Guanzhong PlainAfter founding the Sui, Emperor Wen integrated Northern Zhou and Northern Qi experience in lime burning and mortar mixing, standardizing the proportions of lime, sand, and water in palace repairs and granary works, laying a material foundation for large-scale capital construction.
2. 582–594Daxing · Guanzhong PlainYuwen Kai directed the building of Daxing; rammed-earth walls faced with brick and stone, palace terraces, and drainage channels were widely laid and pointed with lime mortar, with some key structures incorporating sticky rice juice for stronger bonding, forming a capital building system of unprecedented scale.
3. 590–600Luoyang · Central PlainsIn the late 6th century the Sui built granaries, bridge piers, and waterworks in Luoyang, promoting lime mortar masonry and waterproof pointing techniques; brick and stone arch and revetment work matured, laying material and construction foundations for later large-scale canal excavation.
