In conclusion the invention has the advantages that：
1, the shield duct piece that the present invention is prepared has good anti-permeability performance and compressive property with water-tight concrete, ensures
The water resistance and load-carrying properties in tunnel.
2, carbon fiber can effectively prevent the generation in concrete plasticity phase crack, since fiber is presented three in concrete
Dimension space network structure plays the role of support and gathers materials, and prevents thick, fine aggregate sedimentation to a certain extent；It also drops simultaneously
The low bleed phenomenon of concrete surface effectively prevents to cause plasticity phase larger volume to receive due to the rapid dehydration of concrete surface
Contracting, to inhibit plasticity phase concrete surface crack occur.Meanwhile the concrete strength of mecystasis is extremely low, fiber is in plasticity
The tensile stress generated due to drying shrinkage can be born in the concrete of state, reduce and prevent inside concrete crack under mecystasis
Generation, to effectively increase the mechanical property and anti-permeability performance of concrete.
3, the present invention utilizes the synergistic effect of the chloro- 2- trifluoromethylated benzaldehydes of 4- and 4- fluoro- 2- (trifluoromethyl) phenylacetic acid,
The generation and expansion for reducing inside concrete crack effectively increase the mechanical property and anti-permeability performance of concrete.
4, the present invention is mixed using mineral admixture with cement, and this not only reduces the dosages of cement, while also dropping
The low heat of hydration of cement, has delayed temperature peak of hydration, to avoid concrete surface crack from generating, to improve concrete
Cracking resistance, anti-erosion, anti-carbonation properties.
