Effect of Curing Methods on the Strength of High Performance Cement-Based Materials with SAP
The hydration of high performance cement-based materials, especially with-very low water-to-binder ratio, is very limited.Change in external condition will affect its content of water and later properties.This effect is more serious for ultra-high performance concrete.The effect of short later-stage water curing on the strength of high performance cement-based materials with water-to-binder ratio from 0.18 to 0.24 was studied.The results show that when cement-based materials encounter water in the later stage, SAP absorbed water from the outside again make up for the deficiency of insufficient water curing time in the early stage;the strength is also further increased;higher SAP amount can have a more obvious compensation effect.Therefore, if curing time at the early stage is very short, keeping a proper period of water curing at the later stage is very beneficial for cement-based materials with low water-to-binder ratio, especially mixed with SAP.
