Concrete loses volume as the water it contains from the mixing process, hydrates and evaporates. This loss of volume often causes shrinkage cracking. MasterLife SRA 20 is a shrinkage compensating admix intended for use in design mixes having a controlled slump. Concrete mixes containing MasterLife SRA 20; have reduced drying shrinkage cracking and micro-cracking, improved aesthetics, water tightness and overall durability.
