In this study, t he s ta tus of f uel substitution in Korea cement industry a nd t he c hloride contents o f cement p roducts w ere investigated to consider the revision of KS F 4009. The annual average chloride contents of cement products were 130¡ 485 ppm, and the chloride in cement products was calculated to be 1,033 ppm with increasing the use of waste plastic. As a result from the increase of chloride in cement, the chloride contents in concrete will exceed 0.3 kg/m©ø, if more than 250 kg/m©ø of cement is used. In many countries, the limit of chloride in concrete is decided by the environment where concrete is used and the quantity of cement used in concrete. Considering the inevitable increase in the chloride in cement and concrete due to the increased use of waste plastic and the trends in overseas standards for chloride of concrete, it is thought that the revision of KS F 4009 should be reviewed. |
