High performance concrete (HPC) offers high strength, better  durability properties, and good construction.Moreover, Nehdi et al. also studied the durability of SCC with high  volume replacement materials (FA and ground granulated blast  furnace slag), and concluded that SCC with 50% replacement with  Portland cement of FA and slag can improve the workability and  durability [18].Therefore, one solution to reuse such  industrial wastes and reduce the cost of SCC is the use of mineral  admixtures such as limestone powder, natural pozzolans, GGBFS  and FA.  The amount of FA in concrete for structural use is generally limited  to 15-25% of the total cementitious materials.By combining the characteristics and advantages of HPC and  SCC, high performance self-compacting concrete (HPSCC) can be  produced which possesses the advantages in both forms of fresh  and hardened concrete, i.e. while presenting higher strength and durability, it has a good workability and rheological properties [4-  6].Among these materials, fly ash (FA), a by-product of thermal  power plants, and ground granulated blast furnace slag (GGBFS)  have been reported to improve the mechanical properties and  durability of concrete when used as a cement replacement material  [12,13].In order to maintain sufficient yield value and viscosity of fresh  mix of SCC, and to reduce bleeding, segregation and settlement, the  common practice is to use new generation high range water reducers,  to limit the maximum coarse aggregate size and content, and  to use low water powder ratios or use viscosity modifying admixtures.Kulakowski et al. [21] reviewed the silica fume influence on reinforcement  corrosion in concrete and the effect of metakaolin on  transport properties of concrete were also investigated by  Shekarchi et al. [22].There are also some works on incorporating nanoparticles into  concrete specimens to achieve improved physical and mechanical  properties which most of them have focused on using SiO2  nanoparti However, this would not be achieved without studying its performance  before being widely adopted in construction.This paper investigates the effects of silica nanoparticles, silica  fume and Class F fly ash on rheological, mechanical, thermal, transport  and microstructural properties of HPSCC with different binder  contents.The HPC offers significant economic  and architectural advantages over NSC in similar situations, and  is suited well for constructions that require high durability.Thermal properties were  evaluated by thermogravimetric analysis and transport properties  were evaluated by water absorption, capillary absorption and chloride  ion penetration tests.Moreover, the consumption of natural resources and carbon dioxide  emissions associated with cement production can cause serious  environmental impacts.Concretes containing  large amounts of FA were initially developed for mass  concrete applications to reduce the heat of hydration [15].
