| Abstract | ||
| Self-compacting concrete has an enhanced ability to flow. It is known to result in an increased segregation and bleeding potential. This paper discusses the results of an experimental investigation into the properties of self-compacting concrete mixes having varying dosage of high-performance superplasticizer (Glenium 51) (0.5%-3.0%) L per 100 kg of cement material. The properties investigated are workability on the fresh state of concrete by using one mix with five superplasticizer dosage (0.5%,1.0%,1.5%,2.5% and 3.0%) is used. The workability was assessed using three tests according to the specification of self compacted concrete (slump flow ,L- box differential height and V-funnel tests. The three dosage (1.0%,1.5% and 2.5%) comply with requirement for production of SCC while 0.5% and 3.0% don’t comply with specification requirement .Dosage of superplasticizer need to produce self compacted concrete range between (1.0%-2.5%) L/100 kg of cement according to the condition and material used in this paper . | ||
