Abstract - The innovative usage of recycle products has
for horizontal compressive stress and lateral movement of block [4]. The interlocking blocks are of different shapes and the most common shape is regular or full block (300mm X 150mm X 100mm), half sized (150mm X 150mm X 100mm) and U-Shaped [7,4].
increased in this present scenario. Manufacturing of new product with the utilization of waste product is a challenging job. The necessity of the waste products increases with the decrease in the availability of Natural Resource over a short period. The main objective of this project is to encourage the use of Plastic waste (PW) and Brick Waste (BW) products as constitution of Interlocking Blocks. In this project Interlocking block was made with OPC 53 Grade and by replacing Coarse aggregate and Fine aggregate with Plastic waste of about 5%, 10%, 15% while the Brick Waste (BW) of about 2%, 4%, 6%, 8% respectively. Initially the Plastic waste (PW) was only replaced for the coarse aggregate and the optimum percentage was calculated which is 10% Plastic waste. Next the Plastic waste (PW) was standardized and the Brick Waste (BW) was replaced for fine aggregate. From the experiment conducted 10% Plastic waste (PW) and 4% of Brick Waste (BW) was obtained as the optimum percentage replacement. With this percentage replacement the Interlocking Blocks are casted and compressive tests were conducted.
The construction with the interlocking blocks are does not required a large amount of cement mortar as of conventional bricks masonry. The cement mortars are used only for plastering the wall to resist the structure from the penetration of wind and rain [7]. There is little heterogeneity between normal brick and interlocking blocks and they are: [7].

1.1 Advantages: [7, 4]
1. INTRODUCTION
The conventional brick masonry is a most renowned building material in the construction industry which has extreme properties like durability, cost etc. [7]. The traditional bricks are made with clay and they are treated with high temperature kiln firing [6]. These bricks are produced either by machine or by manually. The conventional bricks can be used for the construction of single story building and not for multi-story building as they are large in size and have less resistance to earthquake [7]. To overcome few of the above and to compete in this rapidly growing construction industry engineers are in search of the new technique and that should be an alternate for conventional burnt clay bricks [6].

The dry assembly of interlocking blocks saves large amount of time and reduces the building cost. They can be shipped easily from one location to another. The manufacturing of these blocks is simple and does not required skilled labors and the production can be done at any geographical locations. Grout hole and channel block are provided to insert steel reinforcement in any point of the building to resist the structure from wind and earthquake.
1.2 Disadvantages: [7]
The Interlocking concrete block are different from the normal bricks. These blocks interlock with each other by means of positive and negative frog on top and bottom of the block [4]. This frog connection does not allow the structure

Interlocking Bricks are not backed; it’s just mud in high density pressure using a pressing machine and allowed to dry naturally. Whereas normal bricks are burned clay materials. The sizes of the interlocking blocks are approximately 2.5 times the size of the normal bricks. The weight of the interlocking block is greater than the equivalent volume of the baked bricks.

As it is the new technique so there lack of proper awareness toward the peoples. As the joints are not entirely resistance to wind and rain, so plastering is required.
