Police investigators arrive at Company A, a ready-mixed concrete company located in Gyeonggi-do.
[Police Investigator: This is a warrant for seizure and search.] A
ready-mixed concrete is made by mixing cement, gravel, sand, water, etc., and additive admixtures.
It is to make ready-mixed concrete that violates KS standards by using an illegal program that uses less expensive cement and increases the amount of admixture that is half the price.
[Lim Gyeong-ho/Head of Intelligent Crime Investigation, Gyeonggi Northern Police Agency: Cement is relatively expensive.
In order to reduce the cost, of course, cement has to be reduced.] In
ready-mixed concrete with manipulated mixing ratio, gravel was put in at most 22% less than KS standards, and cement at most 9%, police said.
It was also found that 14 ready-mixed concrete companies, including Company A, gave 50 million won to 9 quality managers at construction companies who conduct safety inspections, saying, "Please tolerate any defects in quality."
Samples were swapped to pass safety tests that measure strength by applying pressure to the sample.
There are 422 construction sites in the metropolitan area where Company A supplied inappropriate ready-mixed concrete from 2017 to October last year in this way.
The delivery amount alone amounts to 90 billion won.
[Remicon company A representative: Sorry, but I think it will be difficult to make a call.] The
police plan to conduct a safety diagnosis with the Ministry of Land, Transport and Industry to select buildings constructed of ready-mixed concrete with low cement content.
