Abstract (eng): | Effects of four types of carbon nanotubes and nanofibers on autogenous shrinkage of cement paste have been investigated. Device for autogenous shrinkage measurement has been set up and tests have been run for each sample for 48 hours. In addition, to support interpretation of the results, bending and compression tests, workability measurement, FE-SEM observation and X-ray diffraction analysis have been carried out. Collected data showed that carbon nanofibers and nanotube, either non-treated or functionalized, could be used to reduce autogenous shrinkage. The uniformity of their dispersion appeared to be the main factor defining their efficiency in reducing the shrinkage. Hence, suitable nanotube/fiber concentration, amount of superplasticizer and sonication time was crucial to decrease the shrinkage. Also nanotube and nanofiber surface properties had an influence on the behaviour towards autogenous shrinkage: better bonding with cement matrix enabled a better shrinkage reduction. |
