By using E-con powder, which consists of ground granulated blast furnace slag and fly ash, we have reduced CO2 emissions by 80% compared to ordinary concrete.

Here is the e-con powder.
eConcrete has 10 times more acid resistance than ordinary concrete.

In addition, since E-Con is a dense effect body, it also has excellent resistance to salt damage.
