Abstract:To strengthen the shield tunnel rapidly, a kind of matrix material with early strength for textile reinforced concrete(TRC) was developed. The performances between the early strength matrix material and fine grained concrete commonly used for TRC were analyzed by conducting uniaxial compression, slump flow, and interface uniaxial tensile and shear tests. Then, the mechanism of the different materials was revealed by SEM and the mechanical models were proposed. The results show that compared with fine grained concrete, the early strength matrix material has more perfect self compacting, penetration and bonding properties; TRC with early strength matrix material show quick strengthening in 2h, and the purpose of rapid strengthening is realized and extensive application prospect is expected.
