This document summarizes a study on the effect of partially replacing cement with silica fume in concrete. Cubes, cylinders and beams were produced with 0%, 5%, 10%, and 15% replacement of cement by silica fume. The specimens were tested for compressive, flexural and split tensile strength at curing periods of 7, 14, and 28 days. The results showed that partial replacement of cement with silica fume significantly improved the strengths, with the highest compressive strength obtained at 10% replacement. Above 10% replacement, the strengths started decreasing. Therefore, 10% was found to be the optimum level of cement replacement with silica fume for high performance concrete with better strength and durability.
Treatments to Improve Concrete Performance - AIAW. R. Meadows
The intent of this presentation from W. R. MEADOWS is to provide the most current information available to explain the basics of cement hydration, and to introduce the various types of floor treatments and curing compounds available. The goal of this presentation is to help the specifying agency and end-user identify the correct material for the project. This program is registered with the AIA/CES for continuing professional education. The course earns one AIA credit.
Geopolymer concrete is a type of concrete that is made by reacting aluminate and
silicate bearing materials with a caustic activator. Commonly, waste materials such as fly ash or
slag from iron and metal production are used, which helps lead to a cleaner environment. Since,
the current usage of fly ash in India is still around 25% and below 45% even in the developed
countries like United States, there is a huge scope for fly ash in upcoming years. So let us harness
a billion dollar resource that has been wasted so far.

Strength And Workability Characteristics Of Super Plasticized Concrete.AshishVivekSukh
The aim of this project is to study the workability and strength characteristics of superplasticized concrete. The investigation is carried out using workability test, compressive strength test, split tensile test and modulus of elasticity test.
This paper reports an investigational study on the effect of calcium carbide kiln
dust (CCKD) in cement mortar and its resistance towards hydrochloric acid attack.
Mortar with various CCKD replacement levels from 5 to 40 percent by binder weight
were tested. The setting time, consistency, density, compressive strength and the
durability tests were evaluated to measure the effect of CCKD in mortar durability was assessed in terms of loss of density and strength when the specimen
were cured in 5% hydrochloric acid (HCL) solution. The results indicate that CCKD
replacement levels from 5 to 20 percent performed on par with control mix in terms of
compressive strength, the loss in density and strength were around 30% under acid
curing. However, 30% and above CCKD replacement percentage showed low density
and compressive strength in both conditions. It is concluded that CCKD can be used
as an effective replacement for cement up to 20 percent without affecting the
performance.
As cement is been involved in various contrived effects to the environment, an alternative is necessary for its impacts reduction.Such alternative is done by completely replacing the cement with silicafume and flyash which are the by-products.

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.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
