Failure Modes in Concrete: How Concrete Cracks and Breaks

Concrete may look solid but its internal structure is far from perfect. It contains small pores, weak zones, and tiny cracks that often exist before any external load is applied. These imperfections explain why failure

Why Concrete Curing Is Important After Pouring

Concrete Curing: Why Concrete Needs Water After Pouring Concrete curing is the process of keeping freshly poured concrete moist and at a suitable temperature so it can develop the required strength and durability. Many people

Concrete in Cold Weather: Why It Needs Special Attention

TeamCivil Concrete, Durability

Concrete is one of the strongest, most trusted building materials in the world. But when it comes to concrete in cold weather, things get complicated fast. Cold temperatures slow down the chemical reactions inside concrete.

Understanding ASTM C1202: the Rapid Chloride Permeability Test (RCPT)

Ever looked at a bridge or parking garage and thought, “This thing’s gonna last forever”? Well, probably not. But someone did: the engineer. Thing is, concrete isn’t immortal. If water or salt gets in, especially

What is Physical Salt Attack on Concrete?

TeamCivil Concrete, Durability

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
