1. Introduction
Concrete is a versatile and durable material for construction, but proper design and construction techniques are critical to ensure the safety and longevity of the structure. Design errors and construction defects can compromise the structural integrity and durability of concrete structures. In this article, we will discuss five common mistakes to avoid when designing concrete structures to ensure the structure’s longevity and safety.
2. Not hiring a professional concrete contractor
One of the most significant mistakes when working with concrete is not hiring a professional contractor. A professional contractor has the expertise and experience to ensure that the design, construction, and quality control meet the standards and regulations. Not hiring a professional contractor may result in poor quality control, inadequate structural design, and detailing, and improper construction practices. These can compromise the durability and safety of the structure. [1]
3. Inadequate structural design and detailing
Inadequate structural design and detailing can lead to structural inadequateness and construction defects. The stress in concrete should not exceed its capacity, and the strain should not exceed its strain capacity to avoid structural failure. Poor detailing and inadequate structural design can also lead to concrete defects like cracking, crazing, blistering, delamination, dusting, curling, efflorescence, scaling, and spalling. It is essential to ensure the proper structural design and detailing to avoid these issues. [2] [6]
4. Poor quality control and construction practices
Poor quality control and construction practices can also lead to defects in concrete structures. These defects can result from the use of poor-quality materials, improper mixing of the concrete, inadequate curing, and poor compaction. Poor quality control and construction practices can result in low-grade concrete structures that are vulnerable to cracking, scaling, and spalling. It is essential to ensure that the concrete mix is of the highest quality and that the construction practices meet the standards and regulations. [4] [8]
5. Improper finishing procedures
Improper finishing procedures can also lead to defects in concrete structures. Adding water to the surface can lead to a weak surface that is susceptible to scaling and dusting. Other improper finishing procedures include over-troweling, insufficient troweling, and using the wrong trowel. These can compromise the durability and safety of the structure. It is essential to ensure that the finishing procedures meet the standards and regulations. [7]
6. Failure to understand the behaviour of structures
Failure to understand the behaviour of structures can also lead to design errors that compromise the durability and safety of the structure. An inappropriate or false understanding of the structure’s behaviour is a significant design error that can compromise the design’s purpose. It is crucial to understand the behaviour of the structure to ensure that the design meets the standards and regulations. [9]
7. Conclusion
Concrete is a widely used construction material for structures, but proper design and construction techniques are critical to ensure the safety and longevity of the structure. Design errors and construction defects can compromise the structural integrity and durability of concrete structures. To avoid these issues, it is essential to hire a professional contractor, ensure adequate structural design and detailing, use high-quality materials, follow proper construction practices and finishing procedures, and understand the behaviour of the structure.
