摘　　要：由于粉煤灰－石灰原料的塑性比粘土差，导致该砖在生产过程中坯体破损率高。作者通过掺加石膏、粘土等外掺料以改善粉煤灰－石灰原料的塑性，取得了一定的效果。The plasticities of fly ash and lime are poorer than that of clay and this results in high damage rate of green fly ash bricks in the production process. The author has achieved certain results by adding additions such as gypsum, clay, etc.to improve the plastic properties or fly ash and lime.
