Concrete plays a major role in the construction applications of various concrete structures. It can be used for all high-rise buildings for the needs of durability and strength. We can mold concrete into any shape and size you require. In the manufacture of concrete, the cement used plays a crucial role in achieving its strength and durability properties. Nowadays High strength concrete (HSC) is widely used all over the world and to produce it is necessary to reduce the water/binder ratio and increase the binder content. This investigation mainly focuses on the strength properties of silica fume (SF)-based HSC. In this study, SF was kept at 15% in the production of HSC and also this study involves along with concrete the admixture polyethylene glycol (PEG4000) is added. The affect of adding (PEG 4000) on compressive strength, split tensile test by different percentage of PEG i.e.(0.5%, 1%, 1.5%) were studied for M60, M70 and M80 grades. By observing the results that the optimum dosage age of PEG is 1% for both M60,M70 and M80 grades. The compressive strength value is compared to normal concrete due to the addition of 15% silica fume, the strength is more as our desired grades of concrete. Also, when PEG4000 was added, the mechanical properties increased at 1% of peg 4000 compared to normal concrete having 15% silica fume.
