Influence sulfur and nitrogen bacteria on the durability of cement materials modified polymers
Języki publikacji
Abstrakty
The paper presents the results of the influence of bacteria (sulfur and nitrogen) on the durability of cement mortars CEM I and polymer modified cement mortars. Received results showed the changes of the tightness materials. Sulfur bacteria caused a caulking structure by deposition of corrosion products of sulphate. However, the unsealing of the structure of cement mortars and mortars modified with acrylics and polysiloxanes caused nitrogenous bacteria. Polycarboxylic resin- modified mortars showed the smallest changes after exposure to corrosive environment of the bacteria.
