Novel Techniques for Concrete Curing

Minimizing shrinkage and cracking are important aspects of concrete curing. As the use of high-performance concrete with low water-cementitious material ratio (w/cm) has become more prevalent, some novel techniques have been developed to combat autogenous shrinkage. Internal water curing is often the most effective curing method for high-strength and high-performance concretes with low w/cm. The use of presaturated lightweight aggregate in internal water curing can counteract self-dessication. Another method to prevent self-dessication is the use of superabsorbent polymers. Internal sealing is another effective curing approach. The addition of a water-soluble chemical during mixing can reduce water evaporation from the hardening concrete and water loss to underlying concrete. Research has shown that these methods can be very effective in preventing concrete shrinkage and cracking.
