| Popis: | Experimental studies of the resistance of cement stone and concrete to the influence of mold fungi have been carried out. The effectiveness of the use of nanomodified calcium carbonate and the PHMG biocide as bactericidal additives for concrete has been investigated. The influence of Glenium and C-3 plasticizers on the effectiveness of the action of bactericidal additives has been investigated. Both investigated biocidal additives showed a fungicidal effect on concrete specimens. The use of nanomodified calcium carbonate as a bactericidal additive for concrete is effective as the use of PHMG biocide. The introduction of this bactericidal additives does not reduce the strength of the hardened concrete. |
