    Boiler Material for Large Scale Model Engines

    what happens if i use regular concrete mix?

    I have built three prototype furnace units for my foundry work, one being electric and the other two for gas or oil. The materials used for the liners or interiors have always been of high temperature commercial refractory mix. When you mix this and pay close attention to the ratio of water to...
