Recycling and utilization of industrial and municipal waste in materials production

Yearly, approximately 750 million tons of rice husks is cultivated which generates about 160 million tons of rice husk that are eventually dumped on the environment as a waste to cover a large area of landfill and causes environmental pollution problems as well. The utilization of rice husk in concrete brings a great benefit in addressing both environmental and economic issues. During the combustion process, the lignin and cellulose content of rice husk is removed and a high amount of silica content is left at the end of the process. Ultrahigh-performance concrete (UHPC) which is one of the latest developments in the field of concrete technology contains about 900 kg/m3 up to 1000 kg/m3 of cement. However, cement production industry is responsible for about 7% of CO2 emission generated with enormous effect on the environmental appearances apart from high cost. This study makes a comprehensive review on using rice husk ash as a supplement to cementitious materials on the performance of UHPC.
