Abstract - Nowadays the trends in the construction industry are changing very quickly. A building becomes obsolete during a short time span. It becomes outdated in both function and form. Thus demolitions of such structures are unavoidable. Due to this the concrete wastes increasing day by day. If we can utilize this waste in some form in the industry it will be a big boost from both economical and environmental point of view. There are several papers are suggested and explained different properties of recycled aggregate. This paper gives an outline of review on this recycled aggregate and its properties and gives how it is suitable for the concrete and its advantages and future scope. Key Words: Recycled aggregate, Mechanical properties, Physical properties.

1. INTRODUCTION The vision of a society towards an engineering structure is changing day by day. The new generation trends are clearly different from old generation concepts. The concept about a structure is totally changed, so that the need of changing the face of an existing building is increased. Now the demolition of old building and substitution with new one is a common phenomenon. The main reason behind this are, changes of purpose, expansion of traffic system, structural deterioration, natural disasters (earthquake, flood, tsunami etc.) etc. Because of above reasons we are forced to change the total concept of building. But we have limited resources here. Our aim is to do these changes using minimum amount of resources. Here comes an idea about the recycled aggregate. Using these recycled aggregate large number of construction projects are started in many European, American, Russian and Asian countries. Figure 1.1 shows the comparison between ordinary coarse aggregate and waste concrete aggregate.In India no deep studies are done so far. Here I am presenting a literature review about this types of concrete.

2. LITERATURE REVIWE Hemalatha.B.R.et.al (2008)[3] introduced an idea for developing a sustainable society by reusing and recycling the construction and demolition waste. This paper highlights the composition of construction and demolition waste, the need for its recycling and where it can effectively use in the field of concrete technology. Sami W. Tabsh.et.al(2008)[9] investigated the strength of concrete made with recycled concrete coarse aggregate. They did Abrasion test, soundness test, compressive strength test and tensile strength test. For this study four different
