When positioned in the upper or top portion of the slab thickness, steel reinforcement limits the widths of random cracks that may occur because of concrete shrinkage and temperature restraints ...

If joints can open freely, tensile stresses caused by restrained dry and thermal concrete shrinkage are relieved. Relieving shrinkage stresses reduces the risk of random cracking. Therefore ...

Imagine concrete healing its own cracks like human skin recovering from a cut. That's the vision behind the latest research of Dr. Congrui Grace Jin, published in Materials Today Communications.
