Abstract Cementitious matrices are the fragile materials that possess a low tensile strength. The addition of fibers randomly distributed in these matrices improves their resistance to cracking, substantially. However, the incorporation of fibers into a plain concrete disrupts the granular skeleton and quickly causes problems of mixing as a result of the loss of mixture workability that will be translated into a difficult concrete casting in site. This study was concerned on the one hand with optimizing the fibers reinforced concrete mixes in the fresh state, and on the other hand with assessing the mechanical behaviour of this mixture in the hardened state, in order to establish a compromise between the two states . In this paper optimization of fibers by using different percentages in steel and glass fiber reinforced concrete of grade M 70 have been studied. It optimizes 1.5% for steel Fiber content and 1% for glass fiber content by the volume of cement is used in concrete. Keywords: fibers, fragile materials, cracking, substantially

Concrete is one of the most versatile building materials. ▶ It can cast to fit any structural shape from a cylindrical water storage tank to a rectangular beam or column in a high rise building. ▶ The advantages of using concrete include high compressive strength, good fire resistance, high water resistance, low maintenance, and long service life. ▶ The disadvantages of using concrete include poor tensile strength low strain of fracture and formwork requirement. ▶ The major disadvantage is that concrete develops micro cracks during curing. ▶ It is the rapid propagation of these micro cracks under applied stress that is responsible for the low tensile strength of the materials, hence fibres are added to concrete to overcome these disadvantages. ▶ The addition of fibres in the matrix has many important effects. Most notable among the improved mechanical characteristics of fibre reinforced concrete (FRC) are its superior fracture strength, toughness, impact resistance, flexural strength resistance to fatigue, improving fatigue performance is one of the primary reason for the extensive use of steel fibre reinforced concrete(SFRC) in pavements, bridge decks, offshore structure and machine foundation.

It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services. Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options. In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website. This document will discuss each of the underlying technologies to create and implement an e- commerce website.

The export maintenance system is a fully featured application that can help we manage fruit delivery business and achieve more control and information at a very low cost of total ownership. A fruit export maintains automatically monitors purchase, sales, supplier information. The system includes receiving fruit from the different supplier. Customer order is placed in the system, based on the order fruit has been sales to the customer. The report contains the details about product, purchase, sales, stock, and invoice. The main objective of this project is to computerize the company activities and to provide details about the production process at the fruit export maintenance system. The demand of fresh fruit fruits and processed food items in international and domestic market has shown a decent increase. This estimation is creating a necessity for growing more and more fruit fruits to cater the growing demand of domestic & international market. The customers effectively and hence help for establishing good relation between customer and fruit shop organization. It contains various customized modules for effectively maintaining fruit and stock information accurately and safely. When the fruits are sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically.

CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems! Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected. R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production. An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred. R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance. Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production. It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call! Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Our construction technique sometimes results in failure such as collapse. ToOvercome this failures, we are going to study the addition of polypropylene fiber and crimped steel fiber in the concrete. This will increase the flexural, shear performance and brittleness of thebuilding even in the poor soil packing site. This study also improves the strength of reinforced concrete by providing the combination of polypropylene and crimped steel fiber. This project work polypropylene fiber and crimped steel fiber different percentage (0.4%, 0.8%, 1.2%) are added in the concrete and using M30. Tests on the concrete compressive strength, split tensile strength, flexural resistance. Key Words: Polypropylene fiber, Crimped steel fiber, Compressive strength, Split tensile strength, Flexural resistance. 1. INTRODUCTION The fibers both polypropylene and crimped steel fiber are used to increase the the toughness and crack resistance. With the use of crimped steel fiber we can reduce the conventional reinforcement or even without conventional reinforcement, we can construct building. This fiber will increase the load carrying capacity this result in prevention of the building from collapse even if human errortakesplace in the building, these fibers will prevent from failure by increasing the load carrying capacity. One application of the fiber is to increase the load carrying capacity of concrete subjected to shear. Most of the design methods and tests procedures have been developed only for the evaluation of steel fiber reinforced concrete.Thefibercontrolledthecrack resistance and corrosion of the building. Easy processing Low specific gravity Almost zero water adsorption Good chemical resistance Wide availability and low cost High ductility 1.1 POLYPROPYLENE FIBER Polypropylene fiber is a synthetic fiber formed from a polypropylene melt.Itischeap,abundantlyavailable,andlike all manmade fibers of consistent quality. High ductility and reduction in amount of concrete. Fig-1 Polypropylene fiber 1.2 CRIMPED STEEL FIBER Crimped steel fibers are made from hard drawn steel wire, ensuring high tensile strength and close tolerances. It is glued into bundles, ensuring quick and easy mixing, with perfect homogenous distribution. It has high toughness. Greatly improved impact, fatigue, and resistance. Fig-2 Crimped steel fiber 1.3ADVANTAGESOFHIGHSTRENGTHCONCRETE 1) Reduced maintenance and repair 2) The size of structural members like beams and columns are reduced since smaller section are enough to carry high loads 3) Since the size of members are reduced the cost of formworks are less.

LITERATURE REVIEW [1] SOON POH YA (2014) discussed about the flexural toughness characteristic of steel polypropylene hybrid fiber-reinforced oil palm shell concrete they concluded that the addition of 1% steel fiber and 0.9 % steel and 0.1% of polypropylene hybrid fiber enhanced the compressive and tensile strengths of the oil palm shell fiber reinforced concrete significantly splitting tensile and flexural strengths showed an improvement by up to 83% and 34% for the mixes with 0.9 % steel fiber and 0.1% polypropylene hybrid fiber [2] PLE.O (2011) discussed about the effect of polypropylene fiber reinforced on the mechanical behavior of silty clay. They concluded that in all cases of loading, an improvement in strength and the benefits can reach an average value around 20% under confinement. A fiber reinforcement of 0.6% permits to increase strength limiting values of 100% in tension and the loss of ductility can be exceeded to 68% under confinement. Onthecontrary,under direct tensile tests the reinforced clay exhibits a benefit in ductility. For a fiber content equal to 0.6%, the change in the ductility reaches 62% and this relatively new improvement technique used in geotechnical projects will have to be tested, in France, in real conditions. [3] GONZALO RUANO (2014) discussed about the shear retrofitting of reinforced concrete beams with steel- fiber reinforced concrete. They concluded that the fiber reinforced concrete improves structural properties and moreover the compatability between the base and the retrofitting materials but thinner cracking pattern,prevents the income of aggressive agents increasing the durability of the reinforcement. 3. METHODOLOGY 1) Reviewing the various literatures. 2) Selection of materials and collection of materials (cement, water, fine aggregate, coarse aggregate, polypropylene fiber, crimped steel fiber). 3) Testing of materials. 4) Preparation of mix design for M30. 5) Adding percentage of fibers(0.4%,0.8%,and1.2%). 6) Casting of specimens (cube, cylinder, beams). 7) Testing of specimens (compressive strength, split tensile strength, flexural strength). 8) Analysis of the test results 9) Conclusion and suggestion for future study 4.

CONCLUSION The following conclusions were drawn with thelimitationof experimental investigation. It has been observed that theincorporationoffibers to the mix increases the material toughness both in tension and compression, as represented by the toughness indexesoftheASTMANDJSCEstandards. Compressive strength ofthe concreteisincreasedat 28 days as compared with control mix. There is an increase 21% using crimped steel fiber and polypropylene fiber 102% with the concrete. Increase in the split tensile strength is observed up to 32021% using crimped steel fiber and polypropylene fiber 1.2% with concrete compared to conventional concrete. The flexural strength is also increased 61% using crimped steel fiber and polypropylene fiber 1.2% with RCC. 7. SCOPE FOR FUTURE ENHANCEMENT Fiber dosage can be varied and studied for shear test. Hybrid fiber can be used for the study. Dimensions of the beam can be varied and studied. Orientation of fibers can be studied. 8. REFERENCS 1.
