하이브리드 섬유 사진

underground space with wide section, high-rise buildings and super high-strength concrete,Hybrid Fiber was developed to prevent explosive spalling of concrete and to secure structure performance, fire-resistance and durability.
The Hybrid Fiber was designed to show optimized performance by combination of merits of each type of fiber. So,more than 2 different types of fibers with different length and thickness were combined to show superior refractory effect.
하이브리드 섬유의 특징

Refractory Performance Management standard of High-strength Concrete Columns and Beams (Ministry of Land, Transport, and Maritime affairs, Notification No. 2008-334) The Standards and rules on refractory structure, evacuation, and fire protection prescribed in the Article 2 of Enforcement Decree on Construction and in the Article 3, set out standards and methods to verify refractory performance of columns and beams made of concrete with over 50 MPa of standard compressive strength of design

하이브리드섬유 사용방법
  • Open a bag and put the contents into a B/P conveyor belt or a mixer
  • Concrete mixing : addition according to the optimum mixture ratio
  • Mixing time : same to mixing time for plain concrete
