Compression Test of Lining of Tunnel Fireproof Concretes
The polypropylene, the silica flour and the carbon fiber will be considered to be added into the concrete when test, the orthogonal theory is used in this test, 32 groups samples were made, the heater was put for heating by choosing the RABT curve, the test result was analyzed, the ratio of compressive strength loss is changed with the meter of the polypropylene textile fiber, the silica flour and the carbon fiber, there is a optimality Proportion when the ratio of compressive strength loss is low.
