Investigation of physical properties of bamboo dust with marble powder filled ceramic composites: Sustainable approach for ceramic tiles manufacturing

Abstract

The suggested bamboo and marble dust ceramic systems can be credited with superior qualities. It has a significant impact on the makeup of the crystalline phase. This study unquestionably sets the road for the effective use of bamboo dust and offers insightful information regarding the use of other bamboo dust waste. The present study provided a novel way to construct the ceramic tile by employing bamboo dust to partially replace marble powder as raw material to utilize bamboo dust from the North Eastern States fully. X-ray powder diffraction and scanning electron microscope were used to characterize the impacts of bamboo dust on the various ingredient composition percentages on the chemistry, mineral phase, and morphology of the ceramic tiles made from bamboo dust. The effects of bamboo dust content on macro, microscopic-scale, and surface structures were extensively examined. Results showed that at 1145 °C, the rupture modulus of a sample containing 8% bamboo dust and 4% marble powder reached 41.94 N/mm², while a sample with 0% bamboo dust and 12% marble powder reached 26.26 N/mm². Additionally, it exceeds the specifications for ceramic tiles for its equivalent water absorption capacity, loss of ignition, and linear shrinkage, which were 9.47%, 13.68%, and 3.66%, respectively.
