Resistance of Recycled Aggregate Concrete to Freeze-thaw and Deicing Salts

The paper aims at the topic of sustainable building concerning recycling of waste rubble concrete from demolition. The authorś long-term concern is about utilization of recycled concrete as aggregate in fibre reinforced cementitious composite. The recent investigations aimed at the durability properties of fibre reinforced concrete made entirely from recycled aggregate. Recycled concrete aggregate resistance to freezing and thawing was performed by several methods. The recycled concrete aggregate was used for making of fibre reinforced concrete and the freeze thaw resistance and resistance to deicing salts were tested. Conclusions are drawn and proposals made for application of the fibre reinforced concrete with recycled aggregate.
