Abstract This study deals with the properties of mineral admixtures, by partial replacing cement, in conditions of improved upon performance on compressive and flexural. Trial and error work will be done to investigate the effect of Silica fume and GGBS by partial overtaking cement and keeping same water cement ratio to High Strength concrete. Through this study we are going to cast concrete samples of size 150mmx150mmx150mm (cube), 500 X 100 X 100 mm (beam) several percentages of Silica Fume (5, 8, 10%) and GGBS (25-50%) with partial replacement of cement casted and analyzed, replacing cement partially, to be able to determine the best percentage, which will give optimum compressive strength (M65, M70, M75) and flexural strength. Keywords- Cement, Concrete, Construction Material, Mix Design, Silica Fume, GGBS
I. INTRODUCTION Tertiary blended concretes belong to strata whose intensity characteristics are optimized to highest value as much as possible by the gradual modification of the chemical structure, fineness and particle size distribution, relative to numerous other forms of concretes. The addition of additives, such as pozzolana, granulated slag, or inert filling, will introduce more varieties. This results in different cement 'specifications' in all standards. In a word, triple blended cement is a substitute for mineral admixtures/additives such as pozzolanic admixtures (fly ash, silica fume, granulated slag, etc.) or inert fillers. The significant cement is called triple mixed cement. The physical, compound, and mechanical properties of the substantial, for example its solidarity boundaries (compressive, flexural), have been expanded by these admixtures.
II. MATERIAL AND METHOD A. Ordinary Portland cement of 53 Grade Purchased from ultratech having soundness property in limit and all other properties according to Indian standards B. Aggregates of Pertaining Sieve Size (<20mm IS standard) Collected from Vadgam, Ahmedabad Gujarat having specific gravity 2.6 and all properties according to Indian Standards C. River Sand of Pertaining Sieve Size (<4.75mm IS standard) Collected from Vadgam, Ahmedabad Gujarat following zone 2 and all properties according to Indian Standards D. Super Plasticiser Revised acrylic super-plasticizer for concrete is considered by low water/cement ratio, a high mechanical strength and better workability values. E. Silica Fume Silica fume, a result of the ferrosilicon business, is a profoundly a pozzolanic material that is utilized to improve mechanical and toughness properties of cement. It could be added straightforwardly to concrete as an individual fixing or in a mix of Portland concrete and silica smolder. In the United States, silica rage is utilized prevalently to create concrete with more prominent protection from chloride infiltration for applications like stopping designs, scaffolds, and extension decks.
