Dependence of the properties of acid-resistant ware on the mode of pressing

It is shown that by introducing granodiorite from the Seversky granite quarry, regulating the grain size composition of the masses and using a combined method for preparing raw materials based on the clay of the Buskul deposit, it is possible to obtain acid-resistant bricks with stable properties and dimensions, with a higher strength (105 MPa) and low shrinkage (6.3 %). All properties of such products meet the requirements of GOST 474-90 for acid-resistant bricks of class A. Tab. 5, ill. 1, bibliography: 3 titles.
