Anna University, Chennai, Tamil Nadu, India ---------------------------------------------------------------------***--------------------------------------------------------------------ABSTRACT: Concrete is the most broadly used manmade building material on planet . When cement & water are mixed with sand resulting product is called concrete . Instead of water and coarse aggregate we used magnetic water and steel slag (SS). It gives better strength compare to the conventional concrete . Normally Use of magnetic water(MW) if increased the percentage of compressive strength. The percentage of steel slag is,50% , 60% 70% can be replaced . Due to addition of steel slag it obtain good result.
compared to the normal water .Its improve strength and workability slightly more than that of ordinary water concrete.
KEY WORDS: Magnetic water (MW), steel slag (SS), coarse aggregate, compressive strength.
3. To study the feasibility of utilization of steel slag as coarse aggregate replacement material.
1.INTRODUCTION:
a) Compressive strength
The word concrete originates from the word “concretes”, which means to grow together. Concrete plays a critical role in the design and construction of the society infrastructure. Natural aggregates are usually obtained from natural rocks. They are inert filler materials and depending upon their size they can be seperated into coarse aggregates and fine aggregates. The unit cost of coarse aggregate increase day by day, therefore the use of alternative sources for natural aggregates is becoming increasingly important. slag is a by- product of the iron and steel making process. Its cost is low comparing to natural aggregates. Thus ,this experimental study an attempt is made to use of steel slag , a By-product from steel industry as replacement for coarse aggregate in concrete. It will be cost effective and also a better way for managing its disposal. Magnetic water is an cost high

2. OBJECTIVE OF THE PRESENT STUDY: 1. To study the broader use of the magnetic water for mixing the concrete. 2. To study the possibility of using steel slag as coarse aggregate replacement in concrete.
c) Flexural strength 4. To investigate the strength of replaced concrete with that of conventional concrete. 3. MATERIAL PROPERTIES: 3.1 MAGNETIC WATER 3.2 STEEL SLAG 3.1. MAGNETIC WATER: The Magnetic In this research study, magnetic water is prepared by retaining water in a glass beaker over a circular magnet of 985 Gauss which is obtained from scientific store. The Magnetic water is obtained by placing the beaker filled with |
