Step 1
Place your sheet of plywood in the work area or the wheelbarrow. You should be near a hose so water can be easily added and so the area and tools can be rinsed when it's time to clean up.
Step 2
Portion the materials into a 3:2:2:0.5 ratio so you have 3 parts gravel, 2 parts sand, 2 parts refractory cement and 0.5 parts of the hydrated lime. Follow this ratio regardless of the volume of fireproof concrete you will be making.
Step 4
Add the refractory cement and hydrated lime over the top of the sand and gravel.
Step 5
Mix all dry ingredients together with a shovel. Mix until all components are evenly distributed. Create a depression in the middle of the pile with the shovel to receive the water.
Step 6
Add water to the mixture. Mix the dry materials and water together until the mixture doesn't have any dry pockets. Do not add so much water that the mixture becomes soupy. Water should be added to the mixture at a rate of about 1/2 to 1 gallon at a time and then mixed before adding more water.
Step 7
Continue to add water or more mix in the proper ratio until the concrete is workable. If you can pack a handful of concrete like a snowball and it doesn't fall apart, it is the proper consistency.
Step 8
Fill the forms with a shovel. Use the trowel to scrape off excess and to give the concrete a level surface.
