  • Abstract:
  • In Light weight concrete pumice plays a role as coarse aggregate . In our concrete we are using M-sand and partial replacement of cement using GGBS and Metakaolin . The ratio we are (40% Cement ,50% GGBS ), (50% Cement, 40% GGBS),(60% Cement,30% GGBS), (70% Cement, 20% GGBS ) , ( 80% Cement, 10% GGBS ) and 10% Metakaolin is kept constant in our concrete. As we are using this ratio to get the strength and hardness of the concrete . It reduce the permeability. Cement is major constituent material of the concrete which produced by natural raw material like lime and silica. Once situation may occurs there will be no lime on earth for production. This situation leads to think all people working in construction industry to do research work on cement replacing material and use of it. Industrial wastes like Ground Granulated Blast Furnace Slag (GGBS) show chemical properties similar to cement. Use of GGBS as cement replacement will simultaneously reduces cost of concrete and help to reduce rate of cement consumption. For these light weight aggregate concrete mixes when ‘cement’ was replaced by ‘GGBS’ it is noticed that there is a marginal improvement in the properties studied. One of the vibrant disadvantages of nominal concrete having high dead load (self weight). This heavy self weight will make it to extent an uneconomical structural material. Light weight concrete having low density, reduction of dead load and to increase the thermal insulation. The reduction in density produced by using pumice aggregate as a limited replacement of coarse aggregate in concrete.
