This research revisits on high strength concrete (HSC) using common admixtures, looking at the fundamental requirement to achieve the HSC. Basic requirement of HSC is low water-cement (w/c) ratio. In this project, silica fume (SF) is the mineral admixtures be applied in the mix, and Super plasticizer (SP) is the chemical admixtures used to enhance workability while reducing water content strength are studied. Concrete cubes size 100 x 100 x 100 mm a compressive strength. The highest average 7 MPa. Thus, the expected strength after 28In this study, the mix with 10% of silica fume plasticizer to one m 3 concrete mix seems to produce the best result. J Fundam Appl Sci. 2017, 9(3S), 546-554 547 strength (more than 50 MPa) when compared to common conventional concrete (20 to 40 MPa)[4]. The product can be more economical even though its initial cost can be higher compared to the common conventional concrete. This is because the used of HSC will generate a lighter structure, more long lasting structure and the service life of the structure can be extended. Due to this condition, the structure can resist damage and this will decrease overall cost for maintenances. Proper design and production are the main factor that will influence the quality of the HSC [10][11][12][13][14][15][16][17][18][19][20][21][22].This research will revisit the development of HSC. The used of HSC in the construction industry, especially in the construction of bridges, skyscrapers, mega structures and many other type of structures that demand the used of high strength concrete is the main motivation for this technology [3]. The used of the HSC will be very beneficial since it will reduce the size and weight of the structure and consequently will reduce the size of the foundation. Besides that, the usage of HSC will be more economical for life-cycle cost performance. Further, it will reduce the use of natural resources such as cement and aggregates due to smaller structural elements.The objectives of this research are to design and test HSC mix using state-of-the-art technique in order to achieve mean compressive strength of 40 MPa or more in 7 days, and to investigate the effects of using silica fume (SF) and super plasticizers (SP) on compressive strength of concrete [1].Finally, the effect of carbon fiber in concrete mix will be tested.Based on the literature, the pillars of practical mix design for HSC are low water-cement ratio, used of super plasticizers, application of cement with a high strength [6] potential and application of pozzolans and in particular silica fumes [14,21]. HSC can be produced with water-cement ratios in the range of 0.22-0.40 and the resulting 28-days compressive strength are in the range of 60 to 130 MPa. The maximum size of coarse aggregates should be kept to a minimum at 9-12 mm in order to achieve optimum compressive strength with high cement content and low water-cement ratio. According to [8] to make the concrete mix design for high performance concrete (HPC), the aggregates size used in the matrix...
