Chamotte, clay, powders and aggregates
Loose refractory materials are used to prepare mortars, castables and masses, and also as fill and aggregate.
Chamotte and chamotte aggregate are made to GOST 23037 "Refractory aggregates", refractory clay to GOST 3226 or manufacturer's specifications, powders and fills to manufacturers' specifications.

Grades and types

Chamotte
To GOST 23037. Calcined refractory clay — ground and graded. Chamotte does not shrink, so it is used as an aggregate in refractory castables, masses and mortars; the fraction is matched to the recipe.

Refractory clay
To GOST 3226 or manufacturer's specifications. Plastic refractory clay is the binding component of refractory mortars, masses and coatings. Together with chamotte it forms a composition that sinters into a strong joint when heated.

Chamotte aggregate
To GOST 23037. Chamotte aggregate for refractory castables. Supplied in fractions; the required fractions and their ratio are set by the castable recipe.

Refractory powders
To manufacturer's specifications. Refractory powders for preparing masses and mixes. Composition and fineness as per the certificate; we will select them for your recipe.

Fills
To manufacturer's specifications. Refractory fills for filling voids and expansion gaps so that the masonry can expand freely when heated.

Frequently asked questions
How does chamotte differ from refractory clay?
Chamotte is clay that has already been fired and crushed; it does not shrink and works as an aggregate. Raw refractory clay is a plastic binder for mortars and masses.
Which chamotte fraction should be used for castable?
The fraction is set by the castable or mass recipe. Send the recipe or describe the task — we will select the fractions.
How can an enterprise order chamotte and refractory clay?
Send a request with the grade, quantity and delivery city or attach a specification. We will prepare a commercial offer, sign a contract and deliver the materials across Kazakhstan.
