Název v původním jazyce

Factors afecting formation on ettringite, thaumasite and gypsum in concrete

Popis výsledku v původním jazyce

The presentation gives an outline of individual factors of concrete deterioration and results of a long time monitoring of concrete samples. The monitoring proved that durability of concrete is affected not just by composition of aggregate and the original cement clinker. A series of other processes play a significant role here. Among the most important of the processes belong alkali-silica reactions (ASR), neutralization of sulphate ions, catalytical action of chloride ions, affect of surrounding environment and geological bedrock. Sulphate attack is one of several mechanisms of concrete deterioration. An excess of sulphate leads to determinal chemical and physical changes in the concrete, resulting in increased porosity and permeability and decreasedmechanical properties of the concrete (Marchand, Skalny, Odler, 2002). Laboratory experiments with sodium sulphate solution using samples of concrete from bridge constructions were done. Results of these experiments were obtained using c
