Abstract :

The article investigates the possibilities of obtaining high–quality expanded clay based on the clay of the Gurlen deposit of the Republic of Uzbekistan, with additives from local oil and fat combines – gossypol pitch and local dune sand of Tuprakkala massif. It is determined that the addition of gossypol pitch to the raw mixture within the specified limits significantly increases the swelling of the mass. It was also determined that the addition of dune sand to the mass (together with gossypol pitch) in moderate quantities contributes to an increase in mechanical strength and lengthening of the swelling interval of experimental expanded clay samples.
