Abstract

Now days there is need of better and efficient construction material and method. We have the responsibility to reduce the effect of application of concrete material to environmental effect. In building constructions, the beam is a very important structural member to carry load of the slab. Objective of this paper is to develop a bubbled beam by placing high density polyethylene balls below the neutral axis .reasons to use high density polyethylene balls are light weight, high strength to weight ratio, Non-reactive with other material. By introducing HDPE balls leads to a 5-10% of lighter beams which reduces loads on columns, walls and foundation and of course on entire building. The region below the neutral is in tension and above the neutral axis is in compression. Concrete is weak in tension & strong in compression hence concrete below the neutral axis is not performing any structural function. Specimen of conventional beam and bubbled beam are cast and tested for two point load. Then the results are compare and effects are studied. Self-weight of this developed beams are expected to be reduced with decrease in volume. Hence proving the beams to be economical. Stress-strain behaviour of conventional beam and bubbled beam is observed by application of strain gauges and recorded by strain meter. The various parameters like self-weight ,flexural strength, stress strain behaviour, deflection ,crack pattern are calculated to compare both the specimens and estimation of amount of concrete saved by bubbled beam as compared to conventional beam is calculated. This bubbled beam will be effective for longer span.
