Characteristics of fired clay bricks with pumice additive

摘要

Production of porous and lightweight clay bricks with enhanced thermal conductivity is studied. Pumice was used as an additive to an earthenware brick to produce the pores. SEM-EDS, XRD, XRF and TG-DTA analysis of the raw materials was initially performed. Mixtures containing brick raw materials and pumice were prepared at different proportions (up to 40 wt.%). The semi-dry mixtures were compressed by a hydraulic press under 20 MPa pressure into the mold, and the green bodies were dried, and the
