Geopolymer concrete, E-waste, Workability and Compressive strength

  Abstract


Portland cement concrete industry has grown astronomically in recent years. It will continue to grow as the result of continuous urban development. However, Portland cement concrete posses problems such as durability and carbon dioxide emission. Many concrete structures have shown serious deterioration, way before their intended service life, especially those constructed in a corrosive environment (Mehta 1997). Geopolymer is a class of aluminosilicate binding materials synthesized by thermal activation of solid aluminosilicate base materials such as fly ash, metakaolin, GGBS etc., with an alkali metal hydroxide and silicate solution. These binders are currently attracting widespread attention due to their potential utilization as a high performance, environmental friendly and sustainable alternative to Portland cement India being the largest coal fly-ash producer in the world produces abundant by- product from thermal power plant known as coal fuel ash. E-waste is the problem with which every country is dealing right now. Because there is no method for the disposal of e-waste and with the growth in the consumption of electronic goods this problem is getting bigger and bigger. The most effective way of the disposal of e-waste is through landfill and this method require large land mass which is very difficult to find in these days. So this is a very good concept of using e-waste as an ingredient in concrete by partial replacement of aggregate. We cannot replace it completely as aggregate provides some key properties to concrete like strength, durability and workability. Using e-waste as building material seems right when we look at the amount of aggregate required for making concrete and if we are able to reduce that amount it will be very beneficiary as it reduces the load from the natural resources. In our research work we have partially replaced the aggregate with e-waste. We have casted concrete cubes with 4%, 8%, and 12% and 16% e-waste and compare the compressive strength of concrete with conventional concrete cubes of G30 grade. In our results we have found out that compressive strength of cubes starts increasing when we add e-waste, but after a point it starts decreasing. At the inclusion of 8% e-waste the compressive strength of concrete is 47.25N/mm2 and thereafter it starts decreasing. At the replacement of 12.5% aggregate with e-waste the compressive strength of concrete is 38.50N/mm2.
