Properties of SCC Mixtures with Coarse Recycled Aggregate
Апстракт
Paper presents the results of physical and mechanical testing of concrete mixtures prepared with recycled concrete aggregate. Four series of Self-Compacting Concrete (SCC) were made, with the use of recycled concrete aggregate (RCA), as a substitute for both natural coarse aggregate fractions. These series were designed using the Two Stage Mixing Approach (TSMA), and the properties of the obtained concrete mixtures in fresh and hardened state were recorded. Flowability of fresh mix was determined using slump flow test, while V-funnel and L-box tests were also performed. Compressive strength and also flexural, splitting and bond (pull-off) strength were determined. All of the mixtures showed favourable properties, proving the possibility of the recycled concrete aggregate use for production of worthy SCC.
