Effect of sawdust as porosity agent on final properties of geopolymers

Abstract

leading to materials with good mechanical properties. Time and temperature of curing of geopolymers also present a direct impact on the final mechanical properties of the material. Those parameters have been explored in many studies ranging from 20 to 85 °C and from 1 to 28 days [12, 13] depending on the prepared formulation. In addition, relative humidity has also been controlled in some studies [13]. All parameters as density, porosity and mechanical properties of the geopolymer play an important role for the final application. Hence, a control and evaluation of parameters are required according to the desired application, and then an improvement in acoustic and thermal comfort, for example, in civil construction might also be explored. This work showed the development of geopolymers, the evaluation of temperature of sintering and the effect of the addition of sawdust on final properties, always aiming

Effect of pore former (saw dust) characteristics on the properties of sub‐micron range low‐cost ceramic membranes

“…Recently, few investigations by our research group (Bose et al and Chakraborty et al) affirmed upon the utility of saw dust powder as a potential nonexpensive pore‐forming agent 17,18 . Similar studies were conducted by Pareira et al and Rumaizah et al 19,20 Thus, from the perspective of most competent literature associated with most nonexpensive pore‐forming agents, available prior art in the said area of study using rice husk and saw dust is the most relevant. The available prior art on saw dust‐based ceramic membrane fabrication indicated ability to achieve defect free microfiltration range ceramic membranes.…”
