There are several requirements established in ACI 318-19 (Building Code Requirements for Concrete and Commentary) that concrete materials need to meet; otherwise, it would not be suitable for the construction of a structure. These requirements vary from one structure to ...

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 Poisson’s Ratio of concrete?
Poisson’s ratio of concrete is the ratio of transverse strain to longitudinal strain in concrete specimen subjected to axial loads. The longitudinal strain and vertical strain are produced due to concrete volume reduction under compression load. Volume reduction of concrete specimen ...
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 ...
Modulus of Elasticity of Concrete- Determination and Importance in Design
Modulus of elasticity of concrete(Ec) is defined as the ratio of the applied stress to the corresponding strain. Not only does it demonstrate the ability of concrete to withstand deformation due to applied stress but also its stiffness. In other ...
Concrete Sweating – Phenomenon, Causes and Prevention
Concrete sweating is the phenomena of accumulation of water droplets on the surface of concrete due to the difference in temperature of the outer environment and concrete. A sweating concrete floor can be a real nuisance that can create a ...
