Abstract: This paper discusses the review of researches concerning the possibility of utilising crumb rubber in high strength self- compacting concrete (HSSCC). It has been used as replacement for coarse and fine aggregates at various percentage replacement levels. It will also discuss the possibility of utilizing its fibre as an alternative in high strength self- compacting concrete due to the fact that they have similar characteristics. However, the major problem associated with self-compacting concrete is explosive spalling. When crumb rubber from scrap pneumatic tyre is used as a replacement for aggregates in concretes, the major problem encountered is decrease in mechanical properties even though it has the advantage of sound adsorption and damping effect. The decrease in the quality of mechanical properties is usually remedied by the application of supplementary cementing materials such as fly ash, ground granulated blast furnace slag, silica fumes and other pozzolans. The spalling phenomenon has been discussed and efforts made to overcome it. The importance of supplementary cementing materials in trying to overcome this phenomenon has also been discussed.
