copper slag concrete ppt

Abstract

This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of sand on the properties of high performance concrete (HPC). Eight concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to 100%. Concrete mixes were evaluated for workability, density, compressive strength, tensile strength, flexural strength and durability. The results indicate that there is a slight increase in the HPC density of nearly 5% ....etc

INTRODUCTION


Metal foam is a dispersion of gas bubbles in a metallic bulk material
These are extremely lightweight materials
It contains 50% or more holes
They have some very promising properties

Structure o f metal foam
In metal foams cells are divided into distinct cells. the boundaries of these materials are made of solid material, the interior are voids.


Light weight Al foam
The best quality metal foams presently available
It has a density of from 300 to 1,000 kg/m , that is, ....etc

METAL FOAM

PRESENTED BY :cloud2511


abstractor
A metal foam is a cellular structure consisting of a solid metal, For ex. aluminium, containing a large volume fraction of gas-filled pores.
The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam).
The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces.
The strength of foamed metal possesses a power law relationship to it ....etc

Based on some general principles of quantum mechanics and general theory of relativity, one can argue that space-time is fundamentally not smooth. Instead, in a quantum theory of gravity space-time would have a foamy, jittery nature and would consist of many small, ever-changing, regions in which space and time are not definite, but fluctuate.

In quantum mechanics, and in particular in quantum field theory, Heisenberg uncertainty principle allows energy to briefly decay into particles and antiparticles which then annihilate back to energy ....etc

seminar report ppt for copper based catalytic converter

Abstract

Exhaust emissions of much concern are Hydrocarbon (HC), Carbon Monoxide (CO) and Nitrogen Oxide (NOx) from the automotive vehicles. Catalytic converter oxidizes harmful CO and HC emission to CO2 and H2O in the exhaust system and thus the emission is controlled. There are several types of problems associated with noble metal based catalytic converter. These factors encourage for the possible application of non-noble metal based material such as copper as a catalyst, which may by ....etc

How to present ppt for this topic given the following abstract

A process of making a solder-less element for mechanical and electrical interconnection using copper nano wires. It consists in a structure of nano-posts, which are deposited on two different metal surfaces by copper electroplating through a porous alumina membrane. Electrical and mechanical interconnection is then achieved by pressing the surfaces against each other leading to the permeation and the entanglement of the nanowires. This low temperature process allows saving energy ....etc
