Influence Of Incorporation Of Modified Carbon Nanotubes On Properties Of Concrete

As the research of fiber composites is gradually mature,fiber material technology is transferred to the field of bridge engineering.It has very strong operability,especially the combination of fiber material and concrete material,and the preparation of high performance concrete materials will be beneficial to the new breakthrough of bridge structure,and it has the technical level of bridge monitoring.It is beneficial to improve the monitoring means of the traditional metal sensors,making the monitoring effect more significant.Carbon nanotube nanofibers have super conductive properties.Second only to superconductors,carbon nanotubes are added into concrete to form smart concrete intelligent materials.It is applied to bridge health monitoring,which has great potential for research.Moreover,carbon nanotubes can well fill the inner space of concrete with its nano scale effect,and the prepared carbon nanotube concrete composite also has a great improvement in mechanical properties.However,the practical application of carbon nanotubes still needs to be studied.The dispersion of carbon nanotubes in the matrix has not been completely solved,and the existing dispersion methods have their own advantages and disadvantages.Considering the environmental,economic and other factors,plasma treatment has certain advantages.Therefore,based on this big background,the surface modification of carbon nanotube(CNT)by plasma technology and the preparation of plasma carbon nanotubes(P-CNT)concrete composite material were prepared by plasma technology.The coagulation of modified carbon nanotubes(P-CNT)and unmodified carbon nanotubes(CNT)was studied under the condition of fixed water cement ratio.The influence of compressive strength and crack resistance of soil materials was studied.The effects of modified carbon nanotubes(P-CNT)and unmodified carbon nanotubes(CNT)on the conductivity of cement mortar were studied under the condition of fixed water cement ratio,and the modified carbon nanotubes(P-CNT)and unmodified carbon nanotubes were studied under the fixed water cement ratio(P-CNT).The effect of CNT)on the pressure sensitive property of cement mortar material.
