How do Poor Construction Practices Cause Crack Development in Concrete Elements?
Several poor construction practices, such as inadequate concrete curing, lack of formwork support, insufficient concrete compaction, and adding water to concrete in the field can cause crack development in plastic and hardened concrete. These mistakes reduce concrete strength, which makes ...
4 Types of Cracks in Concrete Columns and their Causes: Video Included
Four types of cracks developed in reinforced concrete column are diagonal cracks, horizontal cracks, splitting cracks, corrosion cracks. The causes of cracks in columns can be incorrect design, faulty construction or overloading, corrosion of reinforcement, isolated settlement of foundations, creep ...
What are the Causes of Cracks in Reinforced Concrete Slab? Video Included
Several factors like poor concrete quality, improper structural design, inappropriate steel bar spacing, large slab span, improper aggregates, etc. are responsible for the development of cracks in RCC slabs. While the issues pertaining to improper structural design can be eliminated ...
How to Determine the Severity of Concrete Cracks?
Various indicators help determine the severity of concrete cracks. The concrete cracks are assumed to be serious if they are active and widening continuously, allow moisture penetration, retain dirt, or are located in a high-visibility area. The structural cracks can ...
How to Reduce the Possibility of Crack Development in Concrete?
