This is a formula for making excellent refractory material to use to line the walls of a melting furnace. I am routinely melting aluminum and brass and I have been looking for a formula that is strong and lasts a long time. All of the formulas that I have seen that use Portland cement need replacing pretty often because Portland does not hold up under heat
(one part cement : two part sand : four part aggregates). Volume of concrete work is taken as 500 cft. Now, in order to determine the quantity of cement in cft., put the cursor on the specific cell of concrete volume and apply the formula i.e. =(D2*1.54*A2)/(A2+B2+C2). Here 1.54 is taken to convert wet volume of concrete to dry volume of concrete
