In this research, the relationship between rusting and non-rusting of lath was evaluated through 30 years of outside exposure in YOKOHAMA using light mortar and general mortar developed and sold in 1986.
The results confirm that there are many cases of full-cross-section neutralization in the exposed test bodies after 20 or 30 years. However, as for rust in the lath, rust is barely visible near the center of the section, even where neutralization is taking place.
