The testimony of an official who has worked in the ready-mixed concrete industry for nearly 40 years has come out.
D, a worker in the ready-mixed concrete industry, worked to supply ready-mixed concrete to large conglomerates such as I-Park.
Mr. D says that it is not uncommon for a ready-mixed concrete company to manipulate the concrete mixing ratio, such as reducing the amount of cement.
At the construction site, it is necessary to inspect the quality of ready-mixed concrete, but it is said that management and supervision are not performed properly due to the close relationship.
The practice of construction site managers receiving rebates from ready-mixed concrete companies has not changed in 40 years.
We will tell you what happened in the newsroom at 7:30 in a moment.
