Characterization of the effect of brick-powder application in lime-based plasters

Abstract

Brick powder is applied in lime plasters as both supplementary cementitious material replacing a part of lime binder and aggregate replacing a part of siliceous sand. The characterization of its effect on the properties of modified plasters is performed using the measurement of a wide set of parameters including bulk density, matrix density, open porosity, compressive strength, bending strength, water absorption coefficient, water vapour diffusion resistance factor, thermal conductivity and specific heat capacity. Experimental results show a positive influence of the brick powder application on the mechanical properties while the other parameters remain satisfactory.
