Using tyres wastes as aggregates in concrete to form rubcrete – mix for engin...eSAT Journals
Abstract This paper presents the results, obtained after replacement of fine and coarse aggregates, in concrete mix, with tyre rubber. The tyre rubber, which has been used in the present study, is obtained after the mechanical trituration process of post – consumed tyres from trucks. Researchers have investigated, over the years, the use of recycled tyre rubber waste as a replacement for aggregate in concrete and its effectiveness. “Rubcrete-Mix” which would result from such replacement is found to have many engineering applications and holds promise in future. Rubcrete also possesses good mechanical properties and is considered to be one of the best and economical ways of recycling the used tyres. The present experimental study has the aim of arriving at the optimum quantity of the replacement material for the aggregates in concrete mixtures, for various engineering applications. For achieving a proper bond with the surrounding concrete paste, the recycled aggregates have been designed with respect to their size, shape and gradation. With the water – cement ratio being kept constant fine and coarse aggregate has been replaced with tyre rubber powder and chipped rubber and also cement has been replaced with silica fume. In preparing the concrete, Portland slag cement has been used along with super plasticizer less than 1% by weight of cement to achieve required workability of the resulting concrete. Furthermore, durability studies have been conducted and mixes have been designed for M30 grade concrete. Keywords: Concrete Mix, Mechanical Properties, Rubber Powder, Chipped Rubber, Silica fume.
Partial Replacement on Cement with Flyash and Cowdung Ashijtsrd
The usage of cement in concrete is rising day by day. Cement is mostly used in Civil Engineering filed due to the infra structures development and urbanization. The production of cement is emitting the carbon dioxide and effect the environmental problem like global warming, etc. The way to reduce carbon dioxide in cement by the waste material. The fly ash is massive waste disposal in power plants. Cow dung is a used for fuel in domestic proposes like cooking, etc. In current year’s engineers has start using the waste materials in structural component and decrease the rate of concrete. This material is under the category of eco friendly green materials under the carbon foot print and continuous alternate grow without harming the environment. The paper is revealed that the fly ash and cow dung is particle replaced with cement in concrete. The cubes are prepared by the dimension of 150 150 150 mm and M25 grade of concrete are used. The cubes are cure under the period of 7 days, 14days and 28 day. The cubes are tested through the compression testing machine. N. V. Manjunath | P. Karthikeyan | J. Kumaraguru | E. Sankar | S.

EXPERIMENTAL INVESTIGATION OF THE PERFORMANCE OF RUBBERIZED CONCRETE MIXTURES...IAEME Publication
Modern urbanization has contributed to an increase in the number of vehicles, resulting in lots of tires ending up as waste every day. It is estimated that almost 1,000 million tires reach the end of their useful life every year, with more than half of them being disposed of without being treated. One approach for making good use of discarded tire rubber is to incorporate it into cement-based materials as natural aggregate substitutes. In this work, scrap tire rubber was used as a partial replacement for coarse aggregates in normal cement concrete in the form of crumb rubber. Three different sizes of crumb tires were used in this experiment - 25.4mm (1 in) x 5mm (0.2in) x 5 mm (0.2in), 50.8 mm (2 in) x 5mm (0.2in) x 5mm (0.2in) and 76.2 mm (3 in) x 5mm (0.2in) x 5 mm (0.2in). The mix design consists of 15% of coarse aggregate content replaced by the crumb rubbers in a mix ratio of 1: 1/2: 31/2: 2: 0.001 by weight, corresponding to cement: water: gravel: sand: Sika® AIR content. Tests were conducted to determine the compressive, tensile, modulus, and air content of the concrete samples. From the test results, it could be concluded that the rubberized concrete produced higher toughness, delayed crack opening width, and ductile failure even though it had lower compressive and tensile strength than the control mix. The geometry and stiffness of the fibers had an influence on the strength of the modified concrete and the increasing aspect ratio of the crumb rubber fibers improved the postcracking behavior of the concrete matrix.

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.

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.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
