In the present work, silica gel is extracted from raw rice husk, incorporated in Plaster of Paris formulations and casted into sheets of varying thicknesses. The sheets were tested for thermal insulation at 60, 100, 150 & 200 °C and compared with blank formulations. Plaster of Paris composites with silica gel have shown remarkable increase in thermal insulation properties and crack resistance. Thermally insulated Plaster of Paris composites with excellent crack resistance have been developed which can be used competently for prolonged times even at high temperatures offering better serviceability and safety to the buildings.

巴黎复合材料高温石膏隔热和抗裂性的改进

在本工作中，硅胶是从稻壳中提取的，并混入巴黎石膏配方中，并浇铸成不同厚度的片材。在60、100、150和200°C下测试了板材的隔热性能，并与空白配方进行了比较。具有硅胶的巴黎复合材料的灰泥已显示出绝热性能和抗裂性的显着提高。已开发出具有极佳抗裂性的巴黎隔热材料的隔热石膏板，即使在高温下也可长时间有效使用，从而为建筑物提供更好的可维修性和安全性。
