Development of SCC In 1986, concrete capable of compaction by its own weight with no need of vibration was proposed In 1988, first successful prototype of self compacting concrete (SCC) was developed in the University of Tokyo by Prof. K. Ozawa and Prof. H. Okamura SCC, that can be compacted in every corner of form work by its own weight, gained market thereafter Three …

Also the UCL method of mix design was extended to higher coarse aggregate contents and different additions. R Gettu [5] developed a mix design methodology self-compacting concrete such concretes based on four steps where simple test procedures were used. Self-compacting concrete with a 90-day compressive strength of about 100 MPa was obtained.

5. INTRODUCTION Concrete that requires little vibration or compaction has been used in Europe since the early 1970s but self- compacting concrete was not developed until the late 1980's in Japan. In Europe it was probably first used in civil works for transportation networks in Sweden in the midl990's. The multi-national, industry lead project "SCC" 1997-2000 and …
