Development of Fly Ash Bricks Using Alccofine as Partial Replacement of Cement

Abstract

With the growing technology in bricks industry and urbanization there is lot of requirements of raw material. Due to the limited availability of non-renewable resources, it is imperative to use additional waste materials when producing bricks in order to protect these resources. To combat the problem of environmental contamination, waste materials like fly ash, silica fume, and blast furnace slag can be utilised in place of clay. So using fly ash in making bricks, we can preserve the clay which is extensively used in clay brick industry. The primary goal of this research is to create fly ash bricks with increased strength properties compared to conventional fly ash bricks utilising alccofine as a partial replacement for cement. These bricks with improved strength characteristics can be used in high rise building, high load bearing wall, industrial structure, irrigation structure etc. the main object of this research is to determine the optimum mix ratio of fly ash bricks using alccofine as partial replacement of cement with improved strength characteristics and to have less weight brick and to have less permeability. The introduction of a new generation substance, “ALCCOFINE-1203”, is the subject of this study. M4 mix also gives the lower avg. water absorption value of 4.75% and efflorescence was slighter. M9 mix gives the avg. water absorption value of 5.01% and efflorescence was also slighter. These bricks have greater strength qualities and highly helpful in decreasing the dead weight of the structure because they weigh less than traditional bricks used in brick masonry. The amount of water seeping through this brick is significantly decreased due to lower water penetration
