The ACI 318-19 set durability demand for concrete based on the category exposure and class exposure of the structure, dependent on the ground and weather situation of the area. Each exposure category contains different class exposure. The class exposure describes ...

Fire Damage Mechanism of RC Structure and Assessment Method
Fire cause concrete surface cracking and crazing, chemical decomposition, and microcracking and spalling. These impacts can significantly change the properties of structural concrete, reducing strength and durability, and altering structural behavior. Assessment and evaluation of damages caused by fire is ...
7 Factors Affecting Abrasion Resistance of Concrete Surface
The main factor that controls abrasion resistance of concrete is the concrete’s compressive strength. The higher the concrete surface strength the better the resistance of concrete against abrasion. Apart from concrete strength, there are several factors such as the use ...
What is Fire Resistance of Concrete? Mechanism and Factors
Fire resistance of concrete is the ability of concrete to withstand fire or to give protection against fire. This involves the ability of concrete structural element to continue perform a specific structural function or confine fire or both. The duration ...
What is Reinforced Concrete? Uses, Benefits, and advantages
Reinforced concrete is a combination of traditional cement concrete with reinforcements (steel bar). This combination is made to use the compressive strength of concrete and tensile strength of steel at the same time, hence, work together to resist many types of ...
Materials for Repair of Concrete Structures – Types and Selection Criteria
There are various types of materials which are used for the repair of concrete structures. For instance, unmodified Portland cement mortar or grout, latex modified Portland cement mortar or concrete, quick setting non-shrink mortar, and polymer concrete. The choice of ...
7 Types of Construction Defects in Reinforced Concrete Structures
Concrete is known to be a very versatile and reliable material, but some construction errors and construction negligence can lead to the development of defects in a concrete structure. These defects in concrete structures can be due to poor construction ...
Concrete Delamination- Causes, Effects, and Precautions
Concrete delamination is the detachment of thin layers of concrete from the concrete surface. The peeled-out concrete surface then becomes prone to all kind of abraders in the atmosphere which consequently weaken the structure. It, therefore, becomes extremely essential to ...
