consists of new airport but also consists of super highways‚ tunnels and double Decker suspended bridges connecting to the main city. The construction of this project was definitely tough since only 7 years were given to complete the entire project. In fact‚ this project was estimated to be completed in 15 years. There are several challenges faced during the construction stage. The main challenge is to construct the airport on a mountainous island. The mountains had to be removed and leveled. 200 million

INTRODUCTION Aggregate is one of the basic constituents of concrete. Its quality is of considerable importance because about three-quarter of the volume of concrete is occupied by aggregates. One of the physical properties of aggregate that influence the property of concrete is the grading of aggregate. The grading of aggregate defines the proportions of particles of different size in the aggregate. The grading of fine (size < 5 mm) and coarse (size > 5 mm) aggregates are generally required
