Awful Practices that are Adopted in Concrete Construction??

Bad practices in concrete construction are a result of poor construction management at the site. Bad practices in concrete construction will not only result in poor quality of the constructed service but also make the safety of the construction into a great concern.

Good construction practice must be a strict system which has to followed by the working individuals on the construction site. The top-level management along with the work contractors and sub-contractors have to see that these practices are followed as required.

Below mentioned are some of the bad construction practices followed on the construction site which are observed practically.

Most Bad Practices in Concrete Construction arises from:

• Poor Construction Methods and Poor Workmanship

• Unsafe working at heights

• Improper Housekeeping

(a) Poor Construction Method and Workmanship:

• Improper training, inadequate quality, and negligence is the major reason behind the poor workmanship and construction methods.

• Poor construction method will specifically result in:

• Poor Reinforcement of details

• Bad Construction Joints

• Poor Compaction

• Higher water content in concrete

• 01. Increased Water Content in Concrete Mix:

High water content to obtain high workability is a bad practice. Increase in water will increase the porosityand the permeability of the concrete that will result in the corrosion of the reinforcement. It will also reduce the basic strength of concrete.

The supervisors and site in charge have to enforce strictly in order to follow correct amount of water-cement -ratio.

• 02. Segregation of Concrete:

• This is an issue observed in the fresh state of the concrete mix. The main reason behind the segregation of the concrete is:

• Harsh Mix of concrete

• Presence of Large-sized aggregates

• Over-vibration of the Mix

• Pouring the fresh mix from heights

• 03. Bleeding of Concrete:

• 5. Improper Compaction:

• Improper compaction is a result of poor workmanship and negligence. The poured concrete has to be rammed and compacted properly. Poor compaction will result in honeycombed concrete. Proper compaction will help in a dense, compact and impermeable concrete structure.
