By volume, it is 3:3:4 portland cement:perlite:silica sand, mixed together thoroughly, then combined with 4 parts fireclay. The dry ingredients are then moistened to the texture of “stiff cookie dough,” packed into a form, and allowed to dry thoroughly before bake-out.
How to Make Refractory Cement?
Refractory cement is a type of mortar used for lining furnaces, fireplaces, and chimneys. It consists of a combination of materials that are resistant to extremely high temperatures, such as alumina, silica, and fire clay. Refractory cement is specifically designed to withstand thermal shock, abrasion, and corrosion while keeping the heat in and preventing the products of combustion from escaping. This guide will provide an overview of how to make refractory cement.
Before you start making refractory cement, you should gather all of the necessary supplies. The ingredients you will need include alumina, silica, and fire clay. You will also need water and a container for mixing. All of these supplies should be available at your local hardware store.
Once you have gathered all of the supplies, the next step is to mix them together. Begin by adding the alumina, silica, and fire clay in equal parts. If the mixture is too dry, you may need to add a little bit of water to achieve the proper consistency. Once you have achieved the desired consistency, you can move on to the next step.
The next step is to transfer the mixture into the container you have set aside for mixing. Begin
