Using of Cavitation Disperser, for Porous Ceramic and Concrete Material Preparation

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.
