Abstract :

Floating concrete is a non structural concrete. GGBS ground granulated blast furnace slag is an environmentally friendly construction material, hence in this paper study on incorporation of GGBS in floating concrete is carried out. The optimum GGBS replacement as cementation material is characterized by high compressive strength, low heat of hydration, resistance to chemical attack, better workability, good durability and cost-effectiveness. The production of GGBS requires little additional energy compared with the energy required for the production of Portland cement. The replacement of Portland cement with GGBS will lead to a significant reduction of carbon dioxide gas emission. GGBS is therefore an environmentally friendly construction material. It can be used to replace as much as 80% of the Portland cement when used in concrete. GGBS concrete has better water impermeability characteristics as well as improved resistance to corrosion and sulphate attack. As a result, the service life of a structure is enhanced and the maintenance cost reduced. Here in this study authors tried to ing the density of concrete below water, pumice is light weight aggregate and aluminium powder as air entraining agent has been used. The results showed that sample 4 gives dosage whose cost is less than that of ick masonry. The optimum results are given by sample 4 which the density of light weight concrete is less than the density of water and hence we can conclude that it gives a higher efficiency and durability and compressive strength.
