What temperature can refractory cement withstand?

High temperature refractory cements are extreme temperature insulation that can withstand operating temperatures up to 2900°F.

Does refractory cement shrink?

Enough water has to be used to hydrate the cement but an excessive amount of water will create shrinkage and a considerable loss of strength. The material should form compactly and have a light film of water on the surface.

Is refractory cement strong?

Properties of Refractory Concrete: The Refractory concrete has good compressive strength. Refractory concrete can withstand at extreme temperatures without any disintegration. Refractory Concrete also has good Tensile strength. It also has a very less amount of shrinkage as compared to conventional concrete.

Can you make refractory cement?

Formula 1 part Furnace cement + 4 parts Perlite (This is by volume. For example, if you use ½ gallon of Furnace cement, you will need to purchase 2 gallons of Perlite.)

Is refractory mortar necessary?

Medium-duty refractory mortars are required by most building codes for the installation of firebrick and flues in chimneys, masonry fireplaces, and similar applications.

How long does it take for refractory cement to dry?

approximately 24 hours
The refractory should be allowed to cure for approximately 24 hours before firing. This is an important time, and the longer you can wait, the better. As with concrete, keep the surface from drying out by covering with a wet cloth or burlap if the weather is hot or dry.

What is a 3000 degree castable refractory mortar?

LOUCAST 3000 Degree Castable Refractory is a dense castable refractory mortar rated for 3000˚F It is low iron content, with high purity. This refractory mortar is designed to successfully withstand high sulphur fuel, reducing atmospheres, carbon deposition, erosion and abrasion.

What can castable refractory cement be used for?

This refractory mortar is designed to successfully withstand high sulphur fuel, reducing atmospheres, carbon deposition, erosion and abrasion. This castable refractory cement can be used for gunning, casting, troweling, or extruding.

What kind of refractory do you use for forges?

This is a 3000 degree F, High Alumina Castable Refractory for making forges. You can cast the entire refractory liner for a forge or just the floor using this material! This material has a very high resistance to flux, if you’re doing a lot of forge welding and have a dedicated forge for forge welding in, this is a great material to use!
