Application of Self-Compacting Concrete in Strengthening of Existing Reinforced Concrete Column

Article Preview

Abstract:

The use of self-compacting concrete (SCC) is spreading worldwide due to its attractive properties in the fresh state as well as after hardening. Two application examples were introduced, one was reinforced concrete (RC) column strengthening with reinforced self-compacting concrete, and the other was with steel jacket and SCC. Economical and social benefits of the two application examples were analyzed. Project examples and applicable analysis show that RC column strengthening with SCC has attractive advantage, such as economy of technique, convenient construction, good construction quality, as well as bearing capacity improved significantly. The second strengthening method can make the best of advantage of SCC and steel material, and has strong global performance, high utilization ratio of the additional new materials, seismic behavior improved obviously, and so on.
