Construction and Demolition (C&D) waste, a major component of the solid waste is defined as a waste. resulting from the construction, renovation and demolition of structures. Till date a significant portion of C&D waste is disposed of in the landfills which not only consumes a considerable amount of landfill volume but also leads to environmental and health risks. As construction cost increases and land area gets scarcer, it becomes vital to take measures that incorporate a solution to the same. Developing a sustainable construction material (PAVER BLOCK) using construction and demolition (C&D) waste by diversion of C&D waste from the main waste stream can help in gaining a substantial area of land. The present study aims to develop C&D waste paver block of size 275 mm × 220 mm × 130 mm. Cement and fly ash were used as a binder along with C&D waste as replacement for natural coarse and fine aggregate
If made and installed properly, paver block pavement is adaptable, aesthetically pleasing, practical, affordable, and requires little to no maintenance. The majority of concrete block pavement built in India has performed admirably, but there are two major issues are sporadic failure brought on by severe surface wear, and variation in block strength. The world's natural resources are running out at the same time that industrial and residential waste production is sharply rising. In order to make up for the lack of natural resources and to find alternative methods of preserving the environment, sustainable development for construction involves the use of non conventional and innovative materials as well as the recycling of waste materials. The amount of waste plastic that has accumulated in the 21st century has created significant challenges for their management.
II. MATERIALS USED AND ITS PROPERTIES
Materials used for the experiment includes ordinary Portland cement of grade 43, fine aggregate of size less than 4.75 mm, coarse aggregate of size less than 4 mm.
The physical properties of the ordinary Portland cement of grade 43 is depicted in Table 1.

B. Coarse aggregate
Construction companies often mine sufficient rock deposits to create crushed stone, which is then crushed into different sizes using a crusher. The resulting crushed stone can subsequently be used to make concrete and asphalt, as well as a base material for roads, driveways and other construction projects. In order to make concrete, which is a strong and long lasting substance, crushed stone is frequently utilised as an aggregate. Additionally, it serves as the base material for paver blocks, giving the pavers a solid base.
C. Fine aggregate
Manufactured sand (M- sand) is artificial sand produced from crushing hard stones into small sand sized angular shaped particles , washed and finely graded to be used as construction aggregate. It is a superior alternative to River sand for construction purpose.
The utilization of C&D waste in production of paver block has productive way of disposal of C&D waste . The cost of paver block is reduced when compared to that of concrete paver block. Paver block made using C&D waste, M sand, coarse aggregate and cement have shown better result. It also shows good heat resistance. Though the compressive strength is low when compared to the concrete paver block it can be used in gardens, pedestrian path and cycle way etc.
