Bricks are widely used in the construction of buildings around the world. Conventional bricks are produced from clay with high-temperature kiln firing or from ordinary Portland cement (OPC) concrete, and thus contain high embodied energy and large carbon footprints. In many areas of the world, there is already a shortage of natural resources material for the production of the conventional brick for environmental production research has been conducted. A wide variety of waste materials have been studied to produce bricks in different methods. The research can be divided into three categories based on the method for the producing bricks from the waste material: firing, cementing & geo polymerization. A mixture of sodium silicate and sodium hydroxide were cured at ambient temperature. The study of geopolymer bricks fly ash, quarry dust, an alkaline solution. For eco-friendly reaction its vital that the material used for such construction should be environment-friendly. In geopolymer bricks, main ingredients of clay burnt or cement based brick is totally replaced by the waste of burnt coal known as fly ash or pulverized fuel ash. Materials rich in silica and alumina is the necessity for the geopolymer synthesis .the activated solutions for polymerization is sodium hydroxide (NaOH) mix with sodium silicate (Na2SiO3) solution in appropriate proportion Percentage of binder and ratio of alkaline liquid to alumina silicates solids ratio had a significant impact on strength of bricks. Bricks were cast in the industrial site from the best mix compressive strength and water absorption was noted. Geopolymer Eco brick and its durability the size of the were adopted was 100mm*100mm*10m m the brick were cast with fly ash to river sand and eco sand (silica sand) with the different ratios of 1:2 1.5, by weight. The optimum water/binder ratio of 0.416 was selected as per available literature. The binder/water ratio solution (NaOH and water) to fly ash. The exposed surface turned slightly softer through an optical microscope, the corroded surface could be seen which increased with time of exposure. After the exposure to the acid solution for 18weeks. The geopolymer samples almost lost it's alkalinity and showed very low weightless in the range from 0.54%to 0.28%of initial weight. Loss of weight was found higher for a specimen with a higher percent of Na2 SiO3.
