- •
An aggregate skeleton dispersion model of SCC was proposed and the restraint mechanism of aggregate was analyzed.
- •
The relation between mortar coating thickness and the drying shrinkage of was established.
- •
The restraint mechanism of aggregate was clarified based on the aggregate skeleton dispersion model and theoretical analysis.
- •
Coarser aggregate provides better restraint on the volume deformation of mortar.
