Cross-sectional thickness of 18μm! To suppress initial plastic shrinkage cracking and prevent peeling and flaking!
"Grace Microfiber" is a fine polypropylene fiber developed for the reinforcement of mortar and concrete. With a cross-sectional thickness of 18μm and a high number of fibers per unit mass, it provides reinforcement effects with a small amount of incorporation into mortar and concrete. It disperses uniformly within the mortar and concrete, suppressing initial plastic shrinkage cracking, and is effective in preventing peeling and spalling. It also demonstrates significant effectiveness as a measure against explosive spalling in high-strength concrete during fires. 【Features】 ■ Suppression of initial plastic shrinkage cracking ■ Prevention of peeling and spalling of concrete fragments (reduction of surface peeling) ■ Prevention of explosive spalling during fires in high-strength concrete ■ NETIS number KT-110030-VE *For more details, please refer to the PDF document or feel free to contact us.
