Technical-economic indicators of self-compacting concrete structures

Abstract

Self compacting concrete (SCC) was presented by Japanese prof. Okamura in 1986. It was developed to increase the quality and durability of concrete structures. This new mixture achieves an adequate compaction under its own weight due to its high fluidity that provides opportunities to create complicate structural and architectural shapes. The higher powder content is often supplemented by waste materials and industrial by-products that make the concrete friendly with the environment. The material costs of SCC are higher than costs of vibrated concrete, but thanks to its workability, it can be placed at a faster rate with no mechanical vibration in a shorter construction period, which leading to cost savings in placement.
