Lightweight concrete, organic waste, physical and mechanical properties, thermal properties


The objective of this research was to investigate physical, mechanical and thermal properties of concrete produced by using zeolite (clinoptiolite) and organic waste (rice husk). The lightweight concrete of 300 and 400 cement contents were produced by adding various amounts ( 5, 10, 15 and 20 %) of rice husk  into the zeolite. The physical, mechanical and thermal properties of the samples were determined after 28 days. According to the experimental results, the compressive strengths of the samples for 300 and 400 cement contents ranged between 145.80 and 132.87 kg/cm2 and between 192.54 and 167.16 kg/cm2, respectively. The unit weights of the samples for 300 and 400 cement contents ranged between 1406 and 1507 kg/m3 and 1559 and 1604 kg/m3, respectively. The water absorption rates of the samples for 300 and 400 cement contents were between 6.17 and 14.19 % and between 4.44 and 7.46%, respectively. In addition, thermal conductivities varied between 0.581 and 0.510 W/mK for 300 cement content and 0.658 and 0.621 W/mK for 400 cement content. In conclusion, rice husk has potential as a material to produce lightweight concrete when considering its strength, resistance and insulation properties.
