Abstract

Bubble beam is a method of virtually eliminating all concrete from the middle of a beam, which is not performing any structural function, thereby dramatically reducing structural dead weight. High density polyethylene hollow spheres replace the in-effective concrete in the beam, thus decreasing the dead weight. The advantages are less energy consumption, both in production, transport and carrying out, less emission - exhaust gases from production and transport, especially CO2 and reduce the material, the load, lower the cost and it is also a green technology. In the bubble beam technology reduce the concrete volume by replacing the spherical bubbles, these are locally available which is called as PEPSI balls, these balls are made up of HDPE (High Density polyethylene). In this experimental program conventional beam and bubble beam are cast with various bubbles arrangement which is continuous arrangement of bubbles within whole beam and two types of alternative bubbles arrangement in the beam. And trying to enhance the increasing strength of that beam but shear capacity of concrete Decreases when bubbles are added. There is a remarkable Decrease in load carrying capacity upto first crack appears.
