Modification of cemnet paste surface using nanofibers based on poly(vinyl-alcohol) (PVA)
Original language description
The difference in size of nano- and macro-materials (or in their volume) is an obstacle for the application of nanofibers in civil engineering. The synergy of these scales can be utilized when macro-material surface is protected by nanofibers. The proposed experiment investigated the possibility of utilizing the nanofiber textile on cement-based materials. The surface of fresh cement paste was coated by Poly(vinyl-alcohol) (PVA) based nanofibers. Nanofiber textiles were laid in three different weights per unit area (namely 0.1, 5.0 and 10.0 g/m2). The weight loss due to water movement through the material surface was monitored for the first 28 days. Reference samples without nanofiber coating were monitored for comparison as well. All the measurementstook place in a laboratory environment and it is obvious from the results that there is no influence of nanofibers on cement paste drying. The surface of samples was optically investigated after the first experiment and in case of higher
