ANNOTATSIYA
Olovbardosh alumosilikat g’ishtlarining xom-ashyolarini sarash bu turdagi
gishtlarning granulometrik tarkiga ijibiy tasir ko’rsatadi
va yuqori temperaturalarga
bardoshliligini oshiradi.
Kalit so’zlar: Olovbardosh g’isht, saralsh, granulometrik tarkib, soz tuproq, Sito-
burat, fraksiya, shamot.
ANALYSIS OF THE INFLUENCE OF THE SORTING PROCESS ON THE
PROPERTIES OF ALUMINOSILICATE REFRACTORY BRICKS
ABSTRACT
Sorting of raw materials of refractory aluminosilicate bricks has a positive effect
on the granulometric composition of this type of brick and increases its resistance to
high temperatures.
Key words: refractory brick, gravel, granulometric composition,
clay soil, Sito-
Burat, fraction, chamotte.

g‘ishtdan iborat bo‘lgan.
Bunday g‘isht quyish uchun soztuproqni kuydirib hosil qilingan o‘tga chidamli
loy ya’ni shamot (jadval) bilan qum juda qo‘l keladi.
Tarkibidagi aluminiy oksidi ko‘p bo‘lgan kuydirilmagan gilga kuydirilgan kaolin
