Researching Status and Prospect of Lightweight Aggregates Obtained from Solid Wastes in China
Abstract:
Ceramsite is a typical representation of artificial lightweight aggregates and the new energy saving and soil building materials. It has great prospects for development new material in the field of wall materials innovation and building energy efficiency. Ceramsite prepared from fly ash, coal gangue, sludge and other solid wastes were studied. Its crushing strength was 3.4~13MPa and water absorption was 2.0% ~ 18.0%, which are consistent with national performance targets. And we discussed ceramsite’s main problems in the preparation and application and prospect. To use solid wastes to prepare ceramsite can provide a new space for resource utilization and has better social environment and economic benefits.
