Problems solved by technology

[0004] The concrete in the prior art has been quite mature for the technology of resisting sulphate, acid and alkali substances, etc. However, there is no resistance measure for some bacterial erosion such as anaerobic bacteria, which often causes the concrete body to become moldy, etc., which is not only easy to cause The appearance is green and produces peculiar smell, which will also affect the performance of concrete and may cause corrosion to internal steel bars, etc.
