Abstract Urbanization has taken control over years ago, with set up of factories and industries. This leads to the production of smoke containing lot of harmful gasses including shoot. The quantity of this shoot varies from industry to industry and machinery installed. If the machinery installed is based on coal, it does produce a lot of smoke with huge amount of carbon content. Talking about India where most of the industries are coal based the amount of fly-ash produced is considerably large. In the present experiment, the bricks are mainly constructed by the fly-ash (45-53%), with lime (20-28%), gypsum (2%), cement (0-5%) and sand (25%). It is done in order to improve the engineering properties of the conventional bricks. There are 4 samples prepared for the experimental process and 1 sample is taken from the lot of conventional fly-ash bricks stock. The results are being compared with the clay burnt bricks and the conventional fly-ash brick result. The results as are being compared with the IS code for the clay burnt bricks, i. e., IS code: 3495(part 1 to part 4) and for the fly-ash brick is code: 12894-2002 . The results obtained shows that the compressive strength of all samples at 28 days is far ahead than conventional clay burnt bricks and comparable with conventional fly-ash bricks. The same goes for hardness efflorescence, impact and soundness test. Keywords: Fly-ash, Compressive Strength, Conventional Bricks, Water Absorption, Density, Efflorescence, Impact, Hardness. 1. Introduction Fly-ash is finely divided residue produced due to burning of coal mainly in thermal power plants. It is then collected by the electrostatic precipitator. Their proper disposal has been a cause of concern since long time, which otherwise leads to pollution of air. India is fast growing country with a population of about 1. 324 billion. As per Central electricity authority (CEA) the installed capacity in India as on 28/02/2017 is (31SGW) and 215GW is constituted by thermal power plants, which is 68%. As per ministry of power, govt. of India estimation 1800 million tons of coal will be used every year and 600 million tons of fly-ash will be generated by 2031- 2032. The total quantity of the clay burnt bricks produced annually is approximately 180 billion. Approximately 340 billion tons of clay, about 5000 aces of top soil is being dug out causing soil erosion, deforestation [2]. Manufacturing of bricks requires good quality of clay and uses a weight of 3kg per brick. The total clay taken out from agricultural land per day is over 300 million tons for 10,000 crore bricks. At present, fly-ash is being disposed by two methods dry method and wet method. Dry method is preferred when the quantity of fly-ash is small. In this method fly-ash in dry form is carried away pneumatically from the burner and is deposed on the open ground. In wet method fly-ash is mixed with water and sluiced to the setting pond or dumping areas near the plant. This method is widely adopted as it is cheaper but both the methods causing environmental damage. Now this will be going to create a big problem until there should have a proper solution given. 2. Insights from Previous StudiesIn the study by R. V. SHINDE et.al, 2016, the efforts are made to understand the change in the different engineering properties of fly-ash with addition of different ingredients in it. Mix prepared as (i) Fly- ash, clay, sand [30:40:30], (ii) Fly-ash, cement, stone dust [35: 07:58] (iii) Fly-ash, lime, sand, gypsum [40:30:20:10]. Result shows max compressive strength (174 Kg/cm 2 ) obtained for the third sample with minimum density. All the samples showed zero efflorescence, clear ringing sound, with dense and homogeneous.
