| Abstract |
The effect of composition and firing temperature on porosity and bending strength of porous ceramic plates for using in ventilated facades were investigated. Two byproducts, basalt and lime mud, were used to obtain porous ceramic plates in accordance with the circular economy concept. Basalt, which is a fine powder-based byproduct generated from the processing of basaltic rock, was used to replace feldspar as the flux mineral in a ceramic composition. Lime mud, a byproduct of the pulp and paper mill process and containing a high content of calcium carbonate (CaCO3), was incorporated in the ceramic composition to generate pores. The specimens were prepared using three different amounts of lime mud (20, 30, and 40 wt%) and three firing temperatures (900 degrees C, 1000 degrees C, and 1100 degrees C), and their porosity and bending strength were determined. The highest performing specimen (5.1 +/- 1.3 MPa bending strength and 42.6 +/- 0.5% porosity) was obtained by using 40 wt% of lime mud and a firing temperature of 1100 degrees C with potential for further thermal tests in a ventilated facade in comparison with a commercial porcelain ceramic tile as reference material. |
