The cement consumption worldwide is increasing rapidly with vast development in the construction sector. The cement production emits large amount of hazardous carbon-di-oxide to the atmosphere. So control on consumption of cement is not easy, rather use of any other pozzolanic material as partial replacement of OPC is a solution which can reduce cement production. The pozzolanic materials such as fly ash and slag and fly ash have been used previously in cement concrete as a replacement of cement. These pozzolanic materials give good mechanical strength at later age but not at early age. The strength at early age is important for pre-cast members, to reduce stripping time, slab cycle time and the overall construction time. Early age strength is possible with ultra-fine materials such as ultra-fine fly ash and ultra-fine slag in cement concrete. Due to smaller particle size they react much faster and impart better early strength in cement concrete. This paper critically reviews the feasibility of ultra-fine material usage as supplementary cementitious materials. The paper elaborates the mechanical and durability properties with regards to ultra-fine material in cement concrete.
