ABSTRACT In this research our aim is to decide and evaluate the performance of one of the widely used concrete known as high performance concrete (HPC) containing supplementary cementations materials. Due to the better technical as well as economic purpose the concrete gives desired performance in construction that is why the concrete is very much used. The main aim of this investigation program is that consider the locally available materials and using these materials make a concrete grade of M80 strength then after adding the different proportion of Alccofine and fly ash next step to study the effects of different proportions and to find optimum range of Alccofine and fly ash content in the mix. The Alccofine and fly ash is the replacement of weight of the cement. The concrete specimens tested at different age levels, namely 3 days, 7 days, 14 days and 28 days for mechanical properties of concrete such as compressive strength of concrete as well as flexural Strength. Keywords: High Performance Concrete (HPC), Alccofine, Compressive Strength, Pozzalana Material, Flexural Strength, Mix design.

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.

METHODOLOGY
The essential point of this examination was to assess the impact of high volumes of SCMs on the properties of HPC. All the more explicitly, the exploration had the accompanying goals: 1. To contemplate the hydration properties and its essentialness on properties of HPC; 2. To examine the impacts of different substitution levels of FA (class F) and Allcofine on compressive quality and solidness properties of cement; and 3. To assess the compressive reaction of different SCMs on the properties of HPC. allcofine on compressive strength and durability properties of concrete; and 3. To evaluate the compressive response of various SCMs on the properties of HPC.
Importance of High Performance Concrete (HPC) HPC is used as a construction material in structures constructed in very several environments condition. The structures like 1. Tunnels in sea beds 2. Sewage inside tunnels and pipes 3. Off shore piers and platforms 4. Confinements structures for solid and liquid wastes containing toxic chemicals and radioactive elements 5. Sea link bridges pier and superstructures and high rise structures
