INTRODUCTION
According to American Concrete Institute (ACI) is defined explain the High performance concrete(HPC) that meeting special combinations of performance and uniformity requirements that cannot always be achieved routinely using conventional constituents and normal mixing, placing, and curing practices. HPC is extensively used globally where oil, gas, nuclear power plants and high rise buildings are among. High performance concrete is considered as ecofriendly, superior structural performer and energy conserving impicator due to this tremendous properties this concrete demands increases day by day. In conventional concrete cement is used as a binding material which produces a large tonne of CO2 gases after chemical reaction with water. Research on ecofriendly binding material. This research has been conducted on the use of pozzolana materials such as fly ash, volcanic pumice, rice husk, pulverized-fuel ash, blast slag and silica fume and micro silica as cement replacement material. The benefits of these materials can also 1) Improve the durability of concrete 2) The rate of gain in strength of concrete 3) It can also reduce the rate of the liberation of heat, which is beneficial for mass concrete. Concrete containing mineral admixture are used extensively throughout the world for their good performance and for ecological and economic reasons.

6. Chimney and towers, foundations and piles in an aggressive soil environment . Concrete has performed sensibly well in the past in a positive situation, if planned and built appropriately. Concrete Strength, which is effectively controlled by controlling the water-concrete proportion, has served well in the past as the central standard for execution of ordinary cement
Concrete Ingredients ALCCOFINE The Alccofine material is a type of pozzolanic material which is very popular in the construction industry and it is very true that it brought a technical revolution in the era of Civil Engineering. In the case of good workability as well as to achieve high strength Alccofine proof itself tremendous. It is considered as a new generation micro fine concrete material. The application of Alccofine is very easy to use and it can be added directly with cement. The ultrafine particle of Alccofine provides better and smooth surface finish. Just as cost is a concern, for high strength (both in compression and flexure to a large extent) concrete the cost of concrete mix prepared with Alccofine is less than the concrete without Alccofine. The advantage of Alccofine other than strength is that it also lowers the water/binder ratio.
ALCCOFINE 1203 is an uncommonly prepared product dependent on high glass content with high
reactivity got through the cycle of controlled granulation. The crude materials are made fundamentally out of low calcium silicates. The preparing with other select fixings brings about controlled Particle size distribution (PSD). The figured blain esteem dependent on PSD is around 12000cm2/gm. and is genuinely ultra-fine. Because of its extraordinary science and ultra-fine molecule size, ALCCOFINE 1203 gives diminished water request to a given functionality, even up to 70% substitution or replacement level according to necessity of concrete execution. ALCCOFINE 1203 can likewise be utilized as a high range water reducer to improve compressive quality or as a super usefulness help to improve stream.
FOLLOWINGS ARE THE PROPERTIES OF ALCCOFINE: 1) STRENGTH
Alccofine 1203 outcomes in development of dense pore structure and inbuilt Calcium Oxide CaO gives expanded auxiliary hydrated product on account of which improved strength addition at ahead of schedule just as later ages watched.
2) WORKABILITY and COHESIVENESS
Alccofine 1203 contain better particle size dispersion (PSD) contrasted with other supplementary cementations Materials which gives thick lattice pore structure coming about in to reduced water contains and better workability.
3) LOWER THE HEAT OF HYDRATION
Alccofine 1203 has the lime contain 34% which gives more quantum of secondary hydrated product. This outcomes in delayed compound response and liable for decreased heat free by the hydration cycle.
4) FLOWABILITY
Alccofine 1203 has better particle packing which results in expanded rheology coming about in to improved flowability.
Fly Ash
Fly ash is the eco-friendly pozzolanic material which acts as a carbon reducer. Fly ash (FA) class F, referred to as pulverized fuel ash, is the by-product obtained by electrostatic and mechanical methods from vent gases of power station heaters fired with pulverized or pummelled coal. FA is muddled in its compound and stage compositions. It comprises heterogeneous mixes of smooth and translucent stages. Nonetheless, wide ranges exist in the measures of the three head constituents- Silicon Dioxide SiO2 (25 to 60%), DiAluminum Trioxide ,Al2O3 (10 to 30%), and Di Ferrous Trioxide Fe2O3 (5 to 25%). FA can be ordered into two classes, for example Class F and Class C, agreeing to ASTM C 618-99 (1999). In the event that the total of these three fixings is 70% or more noteworthy, the FA is sorted as Class F. However, as Class C, FA for the most part contain noteworthy rates of calcium mixes detailed as CaO, the entirety of the three constituents just referenced is required uniquely to be more prominent than50%. It is commonly acknowledged that, in the pozzolanic response of FA, the Ca(OH)2produced during concrete hydration responds with the silicate and aluminate periods of FA to create calcium silicate and aluminate hydrates (Lea, 1970). Its pozzolanic exercises are credited to the presence of SiO2 and Al2O3 in indistinct structure (Wesche, 1991). Because of its pozzolanic reaction, FA can valuably influence different properties of concrete.

Coarse aggregates consider those aggregates whose dimension greater than 4.75 mm or aggregates retained on 4.75 mm. For high performance concrete, the coarse total particles themselves must be solid. From both quality and rheological contemplations, the coarse total particles ought to be generally equi dimensional; either squashed stone or natural gravel and also meet the IS 383 2016 especially in the event that they are glacial, are reasonable. Likewise, guarantee that the total is perfect, since a layer of residue or dirt will decrease the concrete total bond quality, notwithstanding expanding the water request. The physical properties of coarse aggregate 20mm & 10mm are shown in table 1.
FINE AGGREGATE:
Fine aggregate consider those aggregates whose dimension is less than 4.75 mm or aggregates passing through 4.75 mm. The fine aggregate should comprise smooth adjusted particles and also meet the Zone II of IS 3832016. Fine Aggregate also has the ability to reduce the water demand. It is suggested that the evaluating should lie on the coarser side of the limits, a fineness modulus of 3.0 or more noteworthy is suggested, both to diminish the water prerequisites and to improve the usefulness of these glue rich mixes. Obviously, the sand too should be liberated from residue or clay particles. In this Work, the coarse aggregate choice is of 20mm and 10mm mixed and fine aggregate of characteristic natural sand locally access. The physical properties of fine aggregate confirming zone II is shown in table 1.
Strength Test for High Performance Concrete in Hardened State. COMPRESSIVE STRENGTH TEST:
Compression testing machine is used to determine different proportion of concrete mix for different age of concrete such as 3 Days, 7 Days, 14 Days and 28 Days. For concrete casting cube mould of 150mm x 150mm x 150mm size is taken as per IS: 516-1959 specification. Compressive strength of M80 grade of 3 Days, 7 Days, 14 Days and 28 Days are shown in table 5
FLEXURAL STRENGTH TEST
The beam flexural strength was made according to the Indian standard: 516-1959, determination by flexural machine for various extent of concrete mix. For this examination the concrete beam emissions 100mm x 100mm x 500mm were prepared. All out 2 Nos. of beams were projected or cast for each extent in the Concrete mix. Beams were cured for 28 Days as well as 90 Days’ time age. The beams were put typical to the casting and even two point framework was embraced for the flexural elasticity test. The diversion of the shafts was estimated by the dial measure of LC=0.01mm, which was put in the center third portion of the beam. Flexural strength of M80 grade of 14 Days and 28 Days are shown in table 6.

CONCLUSION
There is five trial mixes namely (TM1, TM2, TM3, TM4 &TM5) after this trail mixes, we concluded perfect proportion of substituting cement material as Alccofine as well as fly ash without losing its strength. Alccofine gives better performance compare than pozzolanic material such as slag material and microsilica. Alccofine provides better workability. By expanding or attempting different dose of Alccofine and flyash we improve result on 8% of Alccofine and 16% of flyash. By checking the different measurements of Alccofine and flyash we get diverse quality at various extent at beginning period of cement till end we get ideal quality at 28 days, so Alccofine assists with expanding strength in both compressive and flexural quality upto certain limit (6%, 7%, 8%).
