This study investigated the mechanical properties of concrete with coal bottom ash used as a partial replacement for fine aggregate at percentages ranging from 0% to 100%. Thirty concrete cubes, fifteen cylinders, and fifteen beams were cast using an M-40 grade concrete mix with a water-to-cement ratio of 0.40. Tests were performed to determine the compressive strength, split tensile strength, and flexural strength of the samples at 7 and 28 days. The results showed that as the percentage of bottom ash replacement increased, the measured strengths generally decreased, with strengths reducing most significantly above 50% replacement. Up to 30% replacement, the strength properties were approximately equivalent to the controlled concrete mix without bottom ash.

Generally, aggregate prepare 60 to 75 of total concrete amount, therefore the aggregate choice is crucial, and additionally they regulate concrete qualities. Aggregate offer wear resistance as well as strength. So, the aggregate selection, as well as proportioning, must need more attention. The aggregate is usually crushed rocks for example limestone, coarse gravel, maybe granite as well as good aggregate like sand or maybe stone dust. Aggregate formed Bulk pavement structure. This research paper represents a review on the utilization of bituminous pavement wastes. This can assist in obtaining economic climate in construction of road along with preserving environment friendly degradation in term of decreased amount of pollution as well as mining.

Study on Flexural Behaviour of Activated Fly Ash Concreteijsrd.com
Cement concrete is the most widely used construction material in many infrastructure projects. The development and use of mineral admixture for cement replacement is growing in construction industry mainly due to the consideration of cost saving, energy saving, environmental production and conservation of resources. Present study is aimed at replacing cement in concrete with activated fly ash. The paper highlights the chemical activation of low calcium fly ash. Today activation of fly ash is playing an important role for enhancing the effectiveness of fly ash and accelerating the pozzolanic properties of fly ash. Activated fly ash certainly improves the early age strength and durability of concrete and corrosion tolerance. Many methods such as mechanical (physical), thermal and chemical activation are in use to activate the fly ash. The chemical activation is one of the easiest methods where fly ash can be activated by alkaline activators (i.e. alkaline solutions of high alkaline concentration chemicals like gypsum, sodium silicate and calcium oxide, KOH, etc.), which enhances the effectiveness of fly ash by disintegrating the glassy layer of fly ash molecules in cement concrete, thereby increasing its corrosion resistance. In the present dissertation, quality of fly ash is improved by chemical treatment by using chemical activators. The mechanical properties like compressive strength, split tensile strength, flexural strength of activated fly ash concrete and flexural strength of activated fly ash reinforced concrete beams are studied. For this project work, the chemicals like sodium silicate, calcium oxide are used to activate the fly ash in the ratio 1:8.

Study on mechanical properties of concrete with industrial wasteseSAT Journals
Abstract
Utilization of Industrial waste, construction waste, agriculture waste, commercial waste etc... In concrete plays a vital role in minimizing the disposal problems. Over 300 million tons of industrial wastes are being produced per annum by chemical and agricultural process in India. These materials poses problems of disposal, health hazards and aesthetic problem. Hypo Sludge (HS) is a waste material produced from paper industry that can used as a cement replacement material in concrete since the lime content in the sludge is large. Copper slag is a waste material produced from copper manufacturing process and this can be used as a replacement material for fine aggregate (sand) since the particle size similar to sand. During the present study, an attempt had been made to study the mechanical properties of concrete in which Hypo sludge and Copper slag were as a replacement material for cement and fine aggregate respectively. Replacement percentage used during this study were 10%, 20% and 30% of Hypo sludge for cement. Fine aggregate was replaced with 30%, 40% and 50% of Copper slag. Compressive strength of cubes were found on 7th, 28th and 56th days. Split tensile strengths of the cylinders were found on 28th and 56th days. Flexural strengths of prism specimens were found on 28th day. It has been found that usage of Hypo sludge and Copper slag as a replacement material has beneficial effects on the Mechanical properties of concrete.
Keywords: Hypo sludge, Copper slag, Compressive strength, Split tensile strength, Flexural strength.
Laboratory Analysis of Fly Ash Mix Cement Concrete for Rigid Pavement.IJERA Editor
This experiment was conducted to investigate the engineering properties of fly ash cement concrete for rigid pavement construction. Results have shown that 30% of fly ash and 70% of cement has a superior performance. In addition, the use of fly ash would result in reduction of the cost of cement which is usually expensive in all construction materials. High strength of concrete can be made by this and the further integration of admixture or alternate adds to improve the properties of concrete. Test result of specimens indicates that the workability and strength chacteristcs are changed due to incorporation with fly ash. Slump test having an appropriate workable mix of a concrete, gave sufficient compressive strength and flexural strength. Test results of 28 days specimens have graphically interpolated for the different results and so that to calculate the optimum content of fly ash.

Studies on quarry dust as partial replacement of fine aggregates in concreteIJLT EMAS
Natural sand is most commonly used fine aggregates
in the production of concrete possess the problem of acute
shortage in many areas. Quarry dust can be used as an economic
alternative to the natural sand. In this investigation an attempt is
made to utilize quarry dust as a partial substitute for natural
sand in producing concrete. Natural sand is replaced by Quarry
dust at an interval of 5%, 10%, 15%, 20% and 25%. Mix
proportions for M20 concrete is prepared with reference to IS:
10262-2009 and IS: 456-2000 for the study of workability.
Compressive strength and Flexural strength test results are
compared with the conventional concrete. The strengths were
obtained at the ages of 3, 7 and 28 days. Compressive and
Flexural strength increased marginally from 5% to 15%
replacement. There is a slight decrease in the corresponding
compressive and flexural strength at 20% replacement. Good
correlation was observed between compressive strength and
flexural strength. It was observed that the addition of quarry
dust that would replace the fine material at particular
proportion has displayed an enhancing effect on properties of
concrete. This investigation proves that quarry dust can be used
as a partial substitute for natural sand in preparing concrete.

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!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
