Salt Scaling Resistance of Concrete with Added Metakaolin

Popis výsledku v původním jazyce

The resistance of high performance concrete to salt scaling was studied in this experimental work. In the concrete mixtures 10% by weight of cement was replaced by metakaolin. The salt-scaling resistance of high performance concrete with metakaolin was compared both to normal concrete and air-entrained concrete. It was found, that the resistance of concrete that contained metakaolin was better compared to normal concrete but worse compared to air-entrained concrete. In addition, during the experimentalwork, it was found that the state of the surface layer has critical influence on the results of the scaling test. The samples where the surface of fresh concrete was brushed to simulate field conditions performed an order of magnitude worse than sampleswith soft surface.
