---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - In the present scenario, concrete use has increased 2. Material Properties very fast. It is shown that the concrete isa the most commonly used material in the world for the engineering works. Especially high strength concrete is nowadays very well utilized in many aspects. To increase the strength and the durability of the concrete some fibers are used here. Steel fiber is commonly used fiber in comparison of other fibers. Jute fiber is best for environmental and economical aspect. In this study the steel fiber and jute fiber is used as hybrid fiber in high strength concrete. With the different percentage of steel fiber and jute fiber has been use in concrete mix. Steel fiber and jute fiber having length of 15 mm and different percent by weight of concrete are 0.00%(conventional), 0.25%, 0.50%, 1.00% and 1.50% were added to prepare concrete cubes and beams. The mix design of concrete has been carried out for the M60 grade of concrete. The compressive strength and flexural strength has been carried out for the different mix proportions of steel fiber and jute fiber. The result shows that the compressive strength was increase till some extent of mix proportion and same for the flexural strength of the different mix proportion.
The various materials are used in making good concrete. The different material properties and its characteristics is need to make good concrete. To make the good performance concrete the material should be proper determined. In this chapter, Here the all required properties to make high strength concrete is determined and the mix design of M60 grade of concrete is calculated and determined. 2.1 Cement Cement is the most needed material in concrete. Cement is a binding material. Generally two types of cement is used 1.Portland cement and 2.ordinary Portland cement. Here in the project the Ordinary Portland Cement (OPC)is taken. There are also grades in ordinary Portland cement which is 33,43 and 54 grade. Here in the project the cement used is OPC 53 grade. For using the cement, it should be confirmed by the Indian Standard Code IS 269 & IS 12269. According to IS 269 the minimum compressive strength of OPC should be 27 MPa. The fineness of cement = 225 m2/kg.

2.2 Fine Aggregate
Fiber, Hybridization of Fiber, Slump, Compressive strength, Flexural strength
Fine aggregate is which passed through 4.75 IS sieve then is called as the fine aggregate. Fine aggregate role is to make concrete dense which is done by filling the voids in concrete due to coarse aggregates by using fine aggregates. Crushed stone, sand, crushed gravel sand all are fine aggregate. According to IS code fine aggregates are divided in four zone; Zone I, II, III and IV. For mixing design of concrete the sand is used.
1. INTRODUCTION In present scenario the use of concrete being increased day by day very fast. The concrete is very most used construction material in the world. Concrete gives the best strength to the building or any structure. The addition of the fibers in the concrete gives the good benefits in form of the cracking resistant, toughness and the strength. High strength concrete used in high rise buildings. The addition of proper percentage of fiber gives more strength to the building. In this chapter, the materials and fibers are introduced. In this chapter the basic information of the concrete and fibers are described. Fibers gives the better strength to the concrete. Concrete is the must needed material in the building and structure and in infrastructure development. Concrete are the widely used material in the construction. We can’t avoid it due to its heavy use in the world. The concrete at some instinct considered as the environmental undesirable. Concrete characterised by its low strength-strain capacity in the tension. Also the low fracture toughness. Concrete can gives the high compressive strength. But concrete can’t provide tensile strength.
