used in modern construction for many purpose such as masonry work, cavity wall, construction of bridges, etc. The hollow reinforced concrete block are generally not closed from all sides, but our present model hollow reinforced concrete block is closed from all sides so that it can be placed in any orientation as per the requirements. In the present work wherein the hollow reinforced concrete block are reinforced with continuous steel wire for strength enhancement and hollow space is created at the centre by incorporating the recycled plastic balls/HDPE ball of spherical shape which offer good sound and thermal insulation property with the help of traditional construction material. Our presented hollow concrete block offers many more advantages such as strength, durability, impermeability, sound and thermal insulation property and also eco- friendly.
Specific gravity: 2.4 Fineness modulus: 2.83 3.
DESIGN OF HOLLOW REINFORCED CONCRETE BLOCK Apart from changing the mix of the concrete, the design of hollow reinforced concrete block also includes modification in the design is like the hollow space is created inside the block by incorporating recycled plastic ball/HDPE ball and the continuous steel wire is provided around the recycled plastic/HDPE ball to enhance the tensile and compressive strength.

1.INTRODUCTION
We prepared the mould of size 600mmX200mmX200mm for flexural strength test and use the mould size of 150mmX150mmX150mm for compressive strength test.
In modern construction, a hollow reinforced concrete blocks are the most important and common member used for wall construction in our country. These days, hollow concrete blocks are quite commonly used in structure. The purpose of this project is to study the properties, applications, and manufacturing process of hollow reinforced concrete blocks. The aim is to highlight their significance in modern construction. In the present hollow reinforced concrete block we used the traditional construction material reinforced with continuous steel wire for strength and created hollow space inside by introducing recycled plastic ball/HDPE ball.
PROPORTIONING The proportioning of the concrete mix is as per the grade M10-1:3:6, M15-1:2:4 and M20- 1:1.5:3. The water-cement ratio of 0.45 by weight is used for hollow reinforced concrete block. MIXING The mixing of cement, crush stone dust, and course aggregate as per the proportion of concrete M10,M15 & M20 use the water 0.45 as water-cement ratio. The prepared mix is discharged from the mixer and consumed within 30 minutes.

PLACING AND COMPACTING Poure the concrete mix into the mould and place the recycled plastic ball/HDPE ball wrapped in continuous steel wire at the centre of mould, pour the concrete from all sides and maintain the cover 25mm from all sides for block and 50mm for bricks.
