FUNCTIONAL MATRIX SYSTEM FOR REFRACTORY LOW-CEMENT COMPOSITE MATERIALS Russian patent published in 2023 - IPC C04B35/66 C04B35/10 B22C1/18 

FIELD: chemical technology.

SUBSTANCE: invention is related to composition of a functional matrix system for low-cement injection moulded thermotechnical composites, which in finished form is a dry mixture for production of new generation thermotechnical refractory composite materials, such as refractory concrete, as well as unmoulded refractories, refractory mortars and mortars. The composition of the functional matrix mixture contains the following ingredients, in wt.%: calcined alumina 20, high-alumina cement 10-20, submicron activated alpha aluminium oxide being the rest, and also a deflocculant based on polycarboxylate ethers in an amount of 0.17 or 0.34 wt.% of the matrix mixture.

EFFECT: increase in the strength properties of concrete and an increase in the spreadability index of the matrix mixture, ensuring a reduction in the water requirement for the concrete mixture.
