Common Defects in Concrete – Causes and Effects

Gul Bahar Shah
  Common Defects in Concrete – Causes and Effects ✳️Concrete is a strong and durable construction material, but poor workmanship, improper mix design, or inadequate curing can lead to several defects that affect performance and durability. Understanding these defects helps engineers maintain better quality control on site. 1. Honeycombing Voids or cavities in concrete caused by poor compaction or insufficient vibration, resulting in weak concrete and possible exposure of reinforcement. 2. Segregation Separation of aggregates from the cement paste, usually due to excess water or improper handling, leading to a non-uniform and weak mix. 3. Bleeding When water rises to the surface of fresh concrete due to a high water–cement ratio, creating a weak and porous surface layer. 4. Cracks Concrete cracks may occur due to shrinkage, thermal stresses, overloading, or poor curing, which can reduce durability and structural performance. 5. Spalling Chipping or breaking of the concrete surf...

Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries

Gul Bahar Shah
Cathodic Corrosion Protection Systems Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries Preface Contents Preface The oil and gas industry depends on steel and other metals for pipelines, storage tanks, and infrastructure. However, these metals can corrode when exposed to water or soil, which is detrimental to the integrity of pipelines and storage tanks. This engineering book outlines the minimum requirements for anodes (high-silicon iron, graphite, magnetite) used in impressed current CP systems. It details the composition, materials, manufacturing, properties, inspection, and testing of these anodes. Additionally, it provides revised survey requirements to ensure corrosion control systems on buried or submerged structures are well-designed, operated, and maintained. The book also covers techniques, equipment, ...
