Abstract: Present paper describes method of obtaining clay
ceramic foam (CCF) and foam concrete (FC), by direct foaming with
high speed mixer-disperser (HSMD). Three foaming agents (FA) are
compared for the FC and CCF production: SCHÄUMUNGSMITTEL
W 53 FLÜSSIG (Zschimmer & Schwarz Gmbh, Germany), SCF-
1245 (Sika, test sample, Latvia) and FAB-12 (Elade, Latvija). CCF
were obtained at 950, 1000°C, 1150°C and 1150°C firing temperature
and have mechanical compressive strength 1.2, 2.55 and 4.3 MPa and
porosity 79.4, 75.1, 71.6%, respectively. Obtained FC has 6-14 MPa
compressive strength and porosity 44-55%. The goal of this work
was development of a sustainable and durable ceramic cellular
structures using HSMD.
