Abstract
Refractory Brick is a material resist the high temperature used in the construction of oven and furnace, it can made from silica and calcium carbonate which is our project objective beside using additive ( KCl,NH4Cl and NaCl) to optimizing the condition of the process.
So, in this project we plan to help producing it economically and environmentally
friendly using waste material that is an impediment for the environment. We believe this will cut the energy cost significantly
In our project the first part is to form CaO from decomposition of CaCO3 and reacted with silica and adding salt,the reaction was done at (800,900,and 1000)ºC and for specific time , the second part of objective is scaling up and do the tests (strength and adsorption test ).
It was found that the optimal condition for using NaCl salt is 900C and 10% concentration for 3 hours according to the compressive strength value of 2.372Mpa.
