This document summarizes an experimental research study that investigated using mica as a partial replacement for fine aggregates in mortar and concrete. The study tested different replacement percentages of mica from 1% to 5% by weight. The chemical composition and physical properties of the materials used were analyzed. Mortar specimens with different mica replacements were tested for compressive and tensile strength at various ages. Concrete mixes using mica replacements were also tested for slump, air content, and compressive strength. The results showed that mica replacements up to 2% can achieve standard mortar strengths but higher replacements reduce strength.
Studies on gold ore tailings as partial replacement of fine aggregates in con...IJLT EMAS
River sand is becoming scarce and meeting the demand
of fine aggregates in the construction industry is becoming a
challenging task. In this investigation an attempt is made to
utilize gold ore tailings as a partial substitute for river sand in
producing concrete. River sand is replaced with 5%, 10%, 15%,
20% and 25% gold ore tailings and the resulting fine aggregates
were used in concrete mix and it is compared with conventional
concrete. Mix proportions for M20 concrete were obtained for
five mixes as per guidelines given in IS: 10262-2009. Workability,
compressive strength and flexural strength are reported. 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 strengths at 20%
replacement. Good correlation was observed between
compressive strength and flexural strength. It was observed that
the addition of gold ore tailings that would replace the fine
material at particular proportion has displayed an enhancing
effect on mechanical properties of concrete. This investigation
proves that gold ore tailings can be used as a partial substitute
for river sand in preparing concrete.

The need for efficient and better construction methods and materials is increasing day by day due to the rapid urbanization taking place around the globe at the same time it is our responsibility to make sure that the application of materials involved in the construction does not create adverse environmental impacts. In this research an attempt to review the optimization of the material usage of a hollow core in Reinforced concrete (RC) flexural members in the zone of tension. This shall facilitate the reduction of the dead loads which is an important factor with respect to seismic effect on structures. This paper studies the research works carried out on RC hollow beams in order to understand the flexural behaviour compared with the conventional solid beams.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

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.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
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.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

The application is develop by using best combination of front-end and back-end languages. The application is totally design like flat user interface. This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users. In 2017, 73% of people enterprises are using windows operating system. So the application will easily install for all the windows operating system users. The application-developed size is very low. The application consumes very low space in disk. Therefore, the user can allocate very minimum local disk space for this application.
