New Possibilities of Determining the Resistance of Cement Composite to Abrasion by Fast Flowing Water

Popis výsledku v původním jazyce

The current view on the determination of the abrasion resistance of a cement composite is mainly focused on the resistance of the composite to the effects of mechanical abrasion. However, many concrete structures are exposed to the abrasive effects of flowing liquids. One of the test procedures simulating this principle of abrasion is based on the creation of a very fast flow of liquids, often including abrasive media. Based on worldwide published research on the given topic,the use of the action of ultrasonic waves in a liquid, leading to the simulation of the cavitation stress of a composite, which is a very dangerous phenomenon, is considered a suitable method for creating the mentioned abrasion effects. The following article discusses new possibilities for simulating and evaluating the abrasive effects of cavitation on cement composites using the action of ultrasonic waves in a liquid. These effects will be monitored on cement pastes, which will be modified with several types of commonly used admixtures. Furthermore, the connection between the effects of the mentioned abrasive action and several physical-mechanical parameters will be monitored.
