I have been working on construction sites for ten years and have led dozens of projects.
To be honest, the bubbles on the surface of concrete are the most headache inducing problem.
You followed the specifications for the mix proportion and did the vibration, but when you removed the mold, it was filled with numerous small holes – it couldn’t pass the inspection, the rectification was time-consuming and laborious, and it also affected the reputation of the project.
Many people’s first reaction is to blame the vibrator, but it’s actually not that simple.
Bubbles are never caused by a single factor, but rather by a combination of materials, proportions, processes, and management.
Today, I will explain the pitfalls I have stepped on and the experiences I have summarized over the past decade in one go.
I suggest that all engineers collect them.
