What is Physical Salt Attack on Concrete?

The topic of physical salt attack (abbreviated as PSA) on concrete is relatively new. ACI 201 “Guide to Durable Concrete” started to mention physical salt attack in their 2016 version. PSA was a subject of

Cathodic Protection of Steel in Concrete: Safeguarding Structures from Corrosion

TeamCivil Concrete, Durability

Cathodic protection is the most expensive method of protection. Engineers usually use it in protecting pipelines in the petroleum industry. Also, it is suitable for use in reinforced concrete structures and also for special structures

Cathodic Protection of Steel in Concrete by Surface Painting

TeamCivil Concrete, Durability

Cathodic Protection for steel inside concrete: The corrosion of steel in concrete occurs as a result of chloride attacks or carbonation of a concrete surface and incursion into the concrete until it reaches steel, which

The Incipient Anode Effect

TeamCivil Concrete, Durability

The Incipient Anode Effect When an area of steel is corroding under the influence of chloride contamination, steel is dissolving causing the formation of iron ‘ions’, tiny charged particles of iron. Simultaneously, electrons are released

Selection of Antifreeze Admixtures

TeamCivil Concrete, Durability

An antifreeze admixture is selected according to the design temperature at which concrete is supposed to harden. If the temperature rises above the design value or even becomes positive as the concrete is cured, its

Ultrasonic Pulse Velocity Testing on Concrete

TeamCivil Concrete, Durability, Tests

What is Ultrasonic Pulse Velocity Testing? Ultrasonic Pulse Velocity (UPV) is an efficient non-destructive testing (NDT) technique for ensuring concrete material quality and identifying structural component damage. Traditionally, the UPV techniques have been employed for material

Causes of Damage in Concrete Structures

TeamCivil Concrete, Durability

Although concrete is considered a durable material for construction, there are factors that cause damage to this durable material. In this article, we discuss some causes of damage in concrete structures. Even if concrete is
