Fresh and Hardened Properties of SCC Made with Different Aggregate and Mineral Admixtures

摘要

The production of self-compacting concrete (SCC) is a relatively new technology. Nowadays, the production of SCC is becoming more popular in Turkey owing to its superior properties. However, the production of SCC requires more sensitive and efficient workmanship and equipment. In addition to many other factors, such as proportioning and curing, the origin of coarse aggregate and mineral admixtures carries utmost importance in terms of fresh and mechanical properties of SCC. The effect of two mineral admixtures-fly ash and limestone powder-and two types of coarse aggregates-limestone and olivine basalt-on fresh and hardened SCC have been investigated within a series of laboratory tests. Results showed that the effect of mineral admixtures on fresh properties seems to be more dominant than the effect of aggregate type. Limestone powder and limestone aggregate combinations had superior fresh and mechanical properties compared to basalt-incorporated mixtures.
