Construction CERAMICS WITH OF CALCIUM CARBONATE SLUDGE ADDITIVES
Abstract
The paper presents research in sludge waste used in the ceramics production. Mechanical-and-physical properties are determined for laboratory samples based on local clays and industrial salt waste depending on their composition. With the burning point increase for sludge-based samples up to 1100°C, their strength decreases due to the gas release from sludge components. At 900-1000°C burning point the sludge additive does not cause substantial changes of mechanical-and-physical properties of ceramics. It is shown that the use of sludge waste allows producing ceramic products having 2184 kg/m3 density and 40,7 MPa compressive strength.
