---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - Concrete is a versatile material extensively used partial replacement of cement in concrete due to its in construction applications throughout the world. It is a inherent pozzolanic properties. Using these waste mixture of cement, sand, coarse aggregate and water. The materials as replacement in cement can replace the production of cement results in emission of many green production of cement substantially on one hand, on the house gases into atmosphere, which are responsible for other hand it shows went for disposal and these industrial global warming. In the present study, effect of pozzolanic wastes as otherwise used as land fill and due to its micro (slag, silica fume, pulverized Quartz powder and) materials structure they acts as micro filler materials there by with addition of micro Fe2O3 is studied through increasing the durability of concrete. compressive, split tensile and flexural strength in cement In this research a comparative study is conducted concrete. Slag, Quartz powder and silica fume are used as to calculate and compare the compressive, split tensile and cement replacement materials at 4%, 8%, 12%, 16% and flexural strength with silica fume, slag and pulverized 20% individually, finding the optimum replacement of Quartz Powder which are used individually and optimum cement individually based on cube compressive strength and replacement is found. Partial replacement of cement was an attempt is made for quaternary blended concrete also done by taking silica fume, slag, and pulverized Quartz with16% of these three pozzolanic materials (slag + silica Powder i.e 5.33% each (Combindly 16%) along with 0.5% fume + pulverized Quartz powder) in three equal parts and to 2.5% micro Fe2O3 to make quaternary and Penta penta blended concrete with addition of 0.5-2.5% of micro blended concrete. The compressive, Split Tensile and Fe2O3 powder with 16% in equal parts by weight of cement. flexural strengths were calculated. Compressive and The results were observed after 7&28 days of water curing Flexural strength testing was done according to IS: 516for M20 grade of concrete. From the test results, it was 1959. Then a comparative result is shown with a table and found that concrete mix with 16% of quaternary blended the variation of the compressive, Split Tensile and flexural cement and 2% of Fe2O3 yielded higher compressive strength comparatively according to the replacement of strength. This experimental work proves that these cement with mineral admixtures is also shown graphically. pozzolanic materials can be used effectively as partial replacement materials for cement in the concrete and The objective of this study is to investigate the makes the concrete more economical and eco-friendly. strength properties of concrete containing partial replacement of cement by slag, silica fume, silicon powder Key words - Silica Fume(SF), Slag(SL), pulverized Quartz and micro iron oxide. Our task is to enhance the strength, Powder(QP), Micro Fe2O3, Binary, Quaternary(T16), and durability and reduce the cost than the conventional Penta blended(T17-T21). concrete. 1.INTRODUCTION 1.1 Literature Review Concrete is widely used construction material for various types of structures due to its structural stability D.Audinarayana (2013): An attempt has been made to and strength. The relative quantities of cement, aggregate study the strength properties of ternary blended concrete and water control the properties of concrete in wet state for various w/b ratios of 0.55, 0.45 and 0.35 for 28, 90 and as well as hardened state. It is no doubt that with the 180 days. They concluded that the combination of micro improvement of human civilization, concrete will continue silica and fly ash leads to increase in compressive strength to be a governing construction material in the future. It is split tensile, flexural strength as compared to control mix probably the most widely used construction material in irrespective of water to binder ratios. the world and it is only second to water as the most profoundly consumed substance with about six billion Naresh Kumar(2014): Investigated on Compressive and tons being produced every year, which is reducing the Flexural strength of binary blended concrete. Metakaolin natural sources and also increasing the CO2 emissions and silica fume are used as cement replacement materials causing green house effect on environment causing gobal at 5%, 10% and 15% by mass keeping water–cement ratio warming.ion.

He concluded that Replacement of Metakaolin cementations materials such as slag, silica fume, fly ash, increase the Compressive Strength at all ages of curing. rice husk ash are waste products, which may be used as
