Abstract -U-Boot technology is capable of supporting
3) U-boot: We have used HDPE recycled plastic material because to reduce wastage of plastics instead of burning the plastics.
large span slabs without beams. U-Boot Beton is recycled formwork. The workspace is placed in the upper centre of the lower reinforcement of the polypropylene slab. It is used to make slabs with large Span or they can support large loads without beams. This is a recycled polypropylene formwork Designed to create lightweight slabs and rafts. The U-Boot system can be combined with other pre-built technologies Techniques such as post-tensioned steel and prefabricated slabs. The technology of hollow slabs with part stretched steel. That Reduces the weight of the slab and cost of the slab.[7]
3.Design of Slab In this test, we used M20 grade concrete. OPC 53 grade cement is used to make concrete and Aggregate of Size 20 mm. The minimum cement contents are equal to 30kg/m3. The water-cement ratio is 0.45 and workability is 50-70 mm. The exposure condition is severe in this casting and the degree of supervision is good. The type of aggregate is crushed angular and there is no use of any chemical admixtures in this casting.
Key Words: U Boot, Polypropylene, Flat Slab, Weight Reduction, Voided Slab, Concrete.
4. LAYOUT OF U-BOOTS
1. INTRODUCTION U-boot is a technology that reduces the volume of Solid required. When U-Boot technology came out in 2001 Robert-II Grande, an Italian engineer, developed and patented a new system of hollow former to reduce traffic Vehicles. This is a recycled polypropylene formwork Technology used for construction. One of these is An important obstacle in construction, for example, The horizontal slab is the increasing weight, which is the ceiling Duration This creates a lightweight economic design for the structure. Reinforcement major development for this reason Concrete emphasizes increasing span. It is used Laying double slabs, large span slabs and mushrooms Slab and raft foundation in RCC structure. Is suitable for Tall buildings, hospitals and parking management Residential and industrial buildings.[4]
LAYOUT OF U-BOOTS
5 Casting of slabs: Form work
2. Materials: U-boot section is made out of three principal materials; they are steel, plastic and cement 1) Concrete: The concrete use is IS 456-2000 has specified the concrete grades of M20. 2) Steel: For our model we have used the steel reinforcement is Fe500 grade, 3mm diameter steel bar is used.
