Review on the mechanism and mitigation of cracks in concrete
Applications in Engineering Science, 2023 Cracks and cavities belong to two basic forms of damage to the concrete structure, which may reduce the load-bearing capacity and tightness of the structure and lead to failures and catastrophes in construction structures.

Plastic shrinkage cracking of concrete − roles of osmotic suction [PDF]
Magazine of Concrete Research, 2011 Plastic shrinkage cracking of concrete occurs when the stresses arising in the concrete, due to a combination of suction and restraints of deformation such as reinforcement or formwork, equal its strength. However, three different types of suctions should be distinguished, namely total, matric and osmotic suctions.

Effect of steel fibers on plastic shrinkage cracking of normal and high strength concretes
Materials Research, 2010 Naturally concrete shrinks when it is subjected to a drying environment. If this shrinkage is restrained, tensile stresses develop and concrete may crack. Plastic shrinkage cracks are especially harmful on slabs.

Using Jute Fiber to Improve Fresh and Hardened Properties of Concrete
Journal of Natural Fibers, 2023 The brittle nature of concrete sometimes makes it challenging for many critical applications. Research has indicated that including discrete short-length, closely spaced fibers in concrete could improve its ductility and act as a crack arrester.
