This document summarizes a study on coconut fiber reinforced concrete. The study aimed to analyze how the strength of coconut fiber concrete varies with different fiber contents and to compare it to conventional concrete. The strengths tested included flexural, compressive, and durability at fiber contents from 1% to 5% of cement weight. Results showed the compressive strength of M20 grade concrete increased at 7 and 28 days with higher fiber contents. Including coconut fibers in concrete enhances its mechanical properties by increasing toughness, flexural strength, energy absorption, and reducing cracking. Factors like fiber content, orientation, aspect ratio, and workability affect the properties of fiber reinforced concrete.

The high cost of materials for anyconventional
building is a major factor that affects the housing delivery
worldwide. This has necessitated research for alternative cost
effective materials in construction. The paper aims at analyzing
characteristic compressive and tensile strength of coconut shells
of concrete produced. By partial replacement using crushed,
granular coconut shells as a substitute for conventional coarse
aggregate in M20 grade concrete. The cube and cylinder are
casted, tested then physical and mechanical properties are
determined. In this studies, three different concrete mixes with
different the combination of natural material content namely
0%, 25%, 50%. Three samples specimen will be prepare for each
concrete mixes. The parameters will be tested are compressive
strength, tensile strength.
This paper analyzed an investigation on the behavior of
concrete specimens produce from coconut shell aggregate. A total
of 36 specimens with varying percentage of replacement were
casted and tested. The attempt is made to prove in all respect the
serviceability and durability, experimental study is satisfying and
can be implemented in rural areas by considering all technical

Fibers are usually used in concrete to control cracking due to plastic shrinkage and to drying shrinkage. They also reduce the permeability of concrete and thus reduce bleeding of water. Some types of fibers produce greater impact–, abrasion–, and shatter–resistance in concrete. Generally fibers do not increase the flexural strength of concrete, and so cannot replace moment–resisting or structural steel reinforcement. Indeed, some fibers actually reduce the strength of concrete.
The amount of fibers added to a concrete mix is expressed as a percentage of the total volume of the composite (concrete and fibers), termed "volume fraction" (Vf). Vf typically ranges from 0.1 to 3%. The aspect ratio (l/d) is calculated by dividing fiber length (l) by its diameter (d). Fibers with a non-circular cross section use an equivalent diameter for the calculation of aspect ratio. If the fiber's modulus of elasticity is higher than the matrix (concrete or mortar binder), they help to carry the load by increasing the tensile strength of the material. Increasing the aspect ratio of the fiber usually segments the flexural strength and toughness of the matrix. However, fibers that are too long tend to "ball" in the mix and create workability problems.
Some recent research[where?] indicated that using fibers in concrete has limited effect on the impact resistance of the materials.[1][2] This finding is very important since traditionally, people think that ductility increases when concrete is reinforced with fibers. The results also indicated that the use of micro fibers offers better impact resistance to that of longer fibers.[1]
The High Speed 1 tunnel linings incorporated concrete containing 1 kg/m³ of polypropylene fibers, of diameter 18 & 32 μm, giving the benefits noted below.
Cracks in concrete are inevitable and are one of the inherent weaknesses of concrete. Water and other salts seep through these cracks, corrosion initiates, and thus reduces the life of concrete. So there was a need to develop an inherent biomaterial, a self - repairing material which can remediate the cracks and fissures in concrete. Bacterial concrete is a material, which can successfully remediate cracks in concrete. This technique is highly desirable because the mineral precipitation induced as a result of microbial activities is pollution free and natural. As the cell wall of bacteria is anionic, metal accumulation (calcite) on the surface of the wall is substantial, thus the entire cell becomes crystalline and they eventually plug the pores and cracks in concrete. This paper discusses the plugging of artificially cracked cement mortar using Bacillus Pasteurii bacteria combined with sand as a filling material in artificially made cuts in cement mortar which was cured in urea and Calcium chloride medium. The effect on the compressive strength and stiffness of the cement mortar cubes due to the mixing of bacteria is also discussed in this paper. It was found that use of bacteria improves the stiffness and compressive strength of concrete. Scanning electron microscope (SEM) is used to document the role of bacteria in microbiologically induced mineral precipitation. Rod like impressions were found on the face of calcite crystals indicating the presence of bacteria in those places.
In this study, bacterial concrete is to be prepared under grade of concrete OPC 43.The design mix proportioning also carried under IS code provision. Testing of specimens are carried at 7 days ,14 days and 28 days of curing by Compression Testing Machine and Universal Testing Machine for corresponding specimens. The Compressive Strength and Flexural Strength of Bacterial Concrete are found.
An Experimental Study of Soil Stabilization with Cement and Polymerijtsrd
The aim of the study was to determine the value of Unconfined compressive strength and CBR values of Soil after stabilizing it with Cement and Polymer. Soil stabilization has been widely used as an alternative to substitute the lack of suitable material on site. The utilization of nontraditional compound stabilizers in soil improvement is developing every day. In this investigation a lab try was led to assess the impacts of waterborne polymer on unconfined pressure quality on sandy soil and CBR Test on clayey soil .The lab tests were performed including grain size of sandy soil, unit weight, and unconfined compressive quality test. The sand and different measures of polymer 2 , 3 , and 4 and concrete 20 , 30 , and 40 were blended in with every one of them into mixture utilizing hand blending in research center conditions. The examples were exposed to unconfined pressure tests to decide their quality following 7 days of restoring. The consequences of the tests showed that the waterborne polymer fundamentally improved the unconfined pressure quality of sandy soils which have weakness of liquefaction. Polymer altered the building properties of soil through physical holding. The amount of polymer required to modify the engineering properties was directly related to specific surface and soil particle coating thickness. Polymer amended soils displayed a reduced performance compared to cement amended soils.

The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
Courier management system project report.pdfKamal Acharya
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.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
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!
