Floating Concrete


This project mainly deals the concrete to float in water by using the combination of light weight aggregate and Air entraining agent of Aluminium powder .The main idea of our project is that the light weight aggregate in the concrete reduces the self- weight of the concrete, so that density of the concrete reduces. Hence the density of the concrete is less than 1000kg/m3, the concrete floats in water. For making this type of light weight concrete, we don’t know the proportion to be mixed in concrete, So that we have adopted the trial and error method to solve this problem. The density of concrete comes under the limit of 500 to 900 kg/m3. The proper mix design of the floating concrete is not arrived, so we have taken the mix ratio from the help of journals. We have used various materials like Fly-ash, gypsum, Lime powder, Pumice stone, Aluminium powder, Polypropylene, GGBS, Vermiculate, Sand, Cement etc. we have successfully achieved the floating property of the concrete from the combination of below ingredients Cement, Lime powder, Gypsum, Fly-ash, Aluminium powder, Polypropylene, Sand . we have partially replacing the cement byFly-ash(48%), Lime(17%), Gypsum(6%), and then fine aggregate of the sand is replaced by 50% of polypropylene. We have added air entraining agent of Aluminium powder by 2- 10%. Finally the floating property and the compressive strength of the concrete are tested.
