PLASTIC SHRINKAGE. Introduction. When a concrete's tensile strength is exceeded by an applied stress, a crack forms in the concrete. Concrete has a relatively low.
Cracks caused by excessive drying from exposed surfaces Plastic shrinkage cracks can form in young concrete, within the first few hours after placing.
Hairline cracking, hair cracking, plastic shrink-age cracks. Very fine cracks, in a random pattern, which usually do not completely penetrate a paint film, an exposed.
Concrete is subjected to changes in volume either autogenous or induced. Volume change is one of the most detrimental properties of concrete, which affects the long-term strength and durability. To the practical engineer, the aspect of volume change in concrete is important from the point of view that it causes unsightly cracks in concrete.
