بیشترLow shrinkage: It is well known that the cementitious repair materials shrink with passage of time. Most of the shrinkage takes place in the initial period, from the time costing to 21 days. If this type of cementitious material is used to repair concrete then it is likely to get delaminated due to de-bonding or develop shrinkage cracks on its surface due to shrinkage strains and stresses.
