POSSIBLE USE OF WASTE CERAMIC DUST AS A SUPPLEMENTARY CEMENTITIOUS MATERIAL IN MORTAR MIX DESIGN

Popis výsledku v původním jazyce

Cement manufacturing has been always ranked in the list of the main sources of carbon emissions among industrial activities. In addressing the environmental concerns of cement manufacturing and problems related to the disposal of wastes and industrial by-product and also economic advantages, supplementary cementitious materials (SCMs) are used in concrete either in blended cements or added separately in the concrete mixer. In this paper, waste ceramic dust originating from the contemporary hollow bricks production is studied as a possible SCM in mortar mix composition. The dust is used in the raw state, without any additionally treatment. For the brick dust and Portland cement, the measurement of chemical composition is done using XRF analysis. XRD device is used for the amorphous phase content measurement. The particle size distribution of ceramics and cement is accessed on a laser diffraction principle. The blended binder containing ceramic powder in an amount of 8, 16, and 24% of mass of cement is used for the preparation of mortars which are then characterised using the measurement of basic physical properties and mechanical properties. Pozzolanic activity of ceramic powder is evaluated using calculated strength activity index. Additionally, pore-size distribution of the developed mortars is analysed using mercury intrusion porosimetry. Experimental data shows that an application of waste brick dust in the amount up to 16 mass% of cement provides sufficient mechanical resistivity of the mortar. The analysed ceramic waste is found to be a pozzolanic material with a promise to contribute to the reduction of CO2 emission in building industry.
