Because rice husk ash is available abundantly at a throw-away price with the large specific surface area and the high reaction activity, it is deemed a valued material, which has demonstrated significant influence in not only improving the development of industrialization but also in keeping the environment free from pollution. This paper presents a comprehensive overview of the work carried out on the use of rice husk ash as pozzolanic material, an adsorbent, as well as a source of silica.  \nKeywords Rice husk ash 􀀂 Pozzolanic material 􀀂 Adsorbent 􀀂 Silica  \nIntroduction  \nNowadays, along with the growing demand for energy of society, looking for a renewable and alternative energy resource generally become an inevitable trend, whether in the industrial countries or in the developing countries, where rapid economic development is necessary. From 2001 to 2015, global energy consumption is expected to have grown by 58 %, an increase from 404 quadrillion kW to 640 quadrillion kW [1] . Therefore, there is an ever-increasing interest in utilizing waste materials worldwide, which, at the same time, conforms to the dominant development direction of the industry, which is a green economy and low-carbon environment protection.  \nRice, which provides a major source of food for billions of people, covers 1 % of the surface of the earth. Rice hull (RH), the outer covering of paddy rice, is an  \n& Yumei Tian[tianym@jlu.edu.cn](tianym@jlu.edu.cn)  \n1 College of Chemistry, Jilin University, Changchun 130012, People’s Republic of China  \nimportant by-product during the milling process and residue ash is generated after the burning of RH and the ash is called rice husk ash (RHA), which is a primary waste material in the agricultural industry. Globally, the annual output of rice paddy is approximately 600 million tons, of which 95 % is produced by 20 countries [2] . Assuming the ratio of a husk to paddy was approximately 20 %[3] and the ratio of an ash to husk was approximately 18 %[4], this also means approximately 22 million tons of RH is produced and about 6.4 million tons of RHA is generated in China alone. So large amounts of RHA become refuse, and may not be available at all, and it is also a big problem to get rid of it [5] .  \nThe typical chemical composition and physical properties of RHA are listed in Table 1 [6–12] . It can be observed that RHA is abundant in silica (SiO2), and the color changes at different calcination temperatures taking place in RHA of which the color is black mixed with some gray or white particles at different degrees. The black particles represent the carbon with incomplete combustion in RHA [13] . Xu [9] had concluded that RHA had three layered structures: inner, outer, and interface with interstitial and honeycombed pores, which were in fact the major cause for the high chemical activity and large specific surface area of RHA, which meant that RHA had a certain reaction activity. If RHA is utilized, it can not only solve the problem of waste disposal but also keep the environment free from pollution. Therefore, the present review is aimed at summarizing the application of RHA indifferent areas.  \nThe application of RHA in building materials  \nOf all the agricultural wastes, RHA, which contains the highest content of silica, is commonly currently regarded as a pozzolanic material [14] . Malhotra and Metha [15] described pozzolanas as siliceous or siliceous and aluminous materials that  \nTable 1 Chemical comp","cbCaicAfS5VQ67BZ","https://ap.wps.com/l/cbCaicAfS5VQ67BZ","pdf",710413,21,"English","# Introduction\n## Rice husk ash as a waste-derived silica material\n## Chemical composition and physical properties\n# The application of rice husk ash in building materials\n## Pozzolanic material role and mechanisms","[{\"question\":\"What is rice husk ash, and why is it valuable?\",\"answer\":\"Rice husk ash is a by-product from burning rice husk, rich in non-crystalline silica.
