EXPERIMENTAL INVESTIGATION ON CONCRETE WITH REPLACEMENT OF COARSE AGGREGATE BY DEMOLISHED BUILDING WASTE WITH STEEL FIBER (LATHE WASTE) S.SAKTHIVEL1, G. ARUN KUMAR2, S. ATHUL3, S. DEEPANJALI4 AND V. KAVIYA5 Department of civil engineering, The kavery engineering college, Mecheri, Tamilnadu, India
Anna University, Chennai, Tamil Nadu, India ---------------------------------------------------------------------***--------------------------------------------------------------------occupy large amount of space .In concrete industry at ABSTRACT: present globally consumes 8 to12 billion tons of natural aggregate annually. Due to continuous use of natural sources like stone and sand is another major problem to change climatic condition and degrading the Earth and also met with demand in future.
There is a large amount of demolished waste are generated every year in India and other developing countries. But very small amount of waste are recycled and reused. So, it have a serious problem to create environmental pollution and also required large amount of space. So, our project deals about reusing of Demolished Concrete Aggregate (DCA) & introduction of Steel Fiber (SF) from the lath wastages are replacing as coarse aggregate in concrete of different percentages 40, 50, 60 DCA& 1% of steel fiber (lathe waste) to minimize the generation of demolished building wastes. The replacement of Demolished Concrete Aggregate(DCA)& Steel fiber(lathe waste) in special concrete of 7, 14, 28 days curing & The various tests to be conducted on concrete such as compressive strength, split tensile strength and flexural strength. The tests values are computed and compared with the conventional concrete.
By the reuse of demolished concrete waste in the form of recycled aggregate concrete is viewed as an attempt to conserve the natural resource and preserving the environment ecologically balance. The recycled aggregate concrete are replacement with coarse aggregate when exceed the limit it have some disadvantages from its characteristics, property and behavior. Some drawbacks of exceeding replacement of recycled aggregate concrete will be improved by adding steel fiber collected from lathe waste. The strength behavior of concrete compressive strength, split tensile strength and flexural strength of special concrete these results are compared to conventional concrete.
KEYWORDS: Demolished Concrete Aggregate (DCA), steel fiber (SF), Lathe waste, coarse aggregate.

1.INTRODUCTION
MATERIAL USED
Due to rapid development of Industries and infrastructure in urban areas the waste generation also increase every year in India. At present, demolition material are dumped on land are treated as waste, which means they cannot be utilized any purpose. A ministry of urban development constructed a first plant that recycles construction waste situated in New Delhi but it is not sufficient to overcome a problem of generating demolished waste. The disposal of Construction & Demolished(C&D) waste are 5000 tons per day according in Hindu and also 23.75 million tons waste is generated annually in India in the year of 2007. It leads to serious problem to pollute environment large and also
