(1) Mixing Proportion
(2) Testing condition
① The test pieces were molded in 40×40×160mm prisms and were demolded after 24 hours,
cured in air until the age of 3 days and kept in a room with a temperature of 20℃ or 80℃.
② The base weight of the test piece was measured at the age of 3days.
③ The test pieces were cured in water for 24 hours
④ The weight of the test piece was measured.
Absorption(%) = [ (④weight) - (②weight) ] / (②weight) × 100
(3) Results
| HANDLING | : Avoid contact with eyes. Avoid prolonged or repeated contact with skin.When handling at elevated temperature, provide adequate ventilation. Avoid rough handling or dropping. |
| FIRST AID MEASURES | |
| EYE | : Immediately flush with clean water until irritation disappear sufficiently, and consult a physician if necessary. |
| SKIN | : Immediately wash thoroughly with plenty of water. |
| INGESTION | : Immediately induce vomiting, and rinse mouth with water. If symptoms are not good after first-aid measures, consult a physician immediately. Do not induce vomiting or give anything by mouth to an unconscious parson. |

- Best fit dosage of PRF series depends on aggregate, mortar temperature and so on, try premix to give objective mortar.
- To the best of our knowledge, although certain hazards are described herein, we cannot guarantee that these are the only hazards which exist.
