Shrinkage and Cracking of Cement Composites Containing Internal Curing Stuff

Name: Work Video:
Duration: 3 min 30 s
Description: The influence of superabsorbent polymers (SAP) as internal curing stuff on the restrained shrinkage and cracking of concrete was investigated. Results show that SAP in the mortar with slag and silica fume increases the compressive train of the steel ring, but postpones the initial cracking time of the mortar from 5 days to 6.5 days and reduces the crack width by 25% at age of 28 days.
