All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). Reinforced concrete is the most common form of concrete.

Efflorescence is the white powdery substance on the surfaces of unsealed concrete and the white blush seen with sealed floors. Efflorescence is caused by vapor migrating through the slab bringing soluble salts to the surface of the concrete. Efflorescence is normally worn off or washed away on unsealed concrete surfaces.Concrete cracking is an inevitable phenomenon that poses challenges to the integrity and durability of structures. Structural cracks weaken concrete, endangering nearby individuals, while Non-Structural cracks can evolve into structural issues. Specific problems range from Alkali-Silica Reaction (ASR) to Thermal Contraction Cracking.Concrete is a widely used construction material known for its strength and durability. However, one common phenomenon associated with concrete is cracking. While it is unrealistic to expect crack-free floors and slabs, understanding the different types of cracks and their causes can help manage and prevent them. Concrete placed during warm midday temperatures will shrink as it cools overnight. A 40 ° F drop in temperature between day and night – which is not uncommon in some areas – would cause a contraction of about 0.03 inches in a 10-foot length of concrete, enough to cause cracks if the concrete is retained. Thermal expansion can cause cracks. Cracks that occur before hardening usually are the result of set-tlement within the concrete mass, or shrinkage of the surface (plastic-shrinkage cracks) caused by rapid loss of water while the concrete is still plastic (Fig. 2).

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. One of the most prevalent faults in concrete constructions is cracking, which, if left …Cracks can develop in RCC slabs due to various factors, including: 1. Shrinkage: Concrete undergoes shrinkage as it cures, which can result in small surface cracks known as shrinkage cracks. These are typically hairline cracks and are considered normal. Proper curing practices can help minimize them.Shrinkage cracks are not continuous through the slab, but are actually cracks in the concrete surface. Corrosion: When reinforcement steel is placed too near the surface, it can corrode. Expansion results as steel is converted to iron oxide through corrosion. This expansion can crack the concrete surface. When the crack is caused by corroding ...Concrete is one of the most durable and long-lasting building materials available.
