Table 3 Fiber addition rate according to fiber type and manufacturer specifications (Nycon, 2019).
From: Study on Early-Age Elastic Modulus of FRC Using Electrical Resistivity and Resonance Frequency
Addition rate | Polypropylene | Nylon | Glass | Steel |
|---|---|---|---|---|
Plastic shrinkage cracking | 0.9 kg/m3 | 0.6 kg/m3 | 0.30–0.60 kg/m3 | 10–15 kg/m3 |
Performance of structure | N/A | N/A | 5–15 kg/m3 | 15–80 kg/m3 |
