稻壳灰水泥砂浆环境影响评价

摘要

采用生命周期评价方法,对普通水泥砂浆和稻壳灰水泥砂浆的生产和使用阶段对环境的影响负荷进行分析.结果表明,稻壳灰水泥砂浆中稻壳灰取代部分水泥,水泥的用量减少,石灰石消耗值ADP也随之减少,同时,稻壳灰作为农业生产的废弃物再次被使用,所需的能源消耗相对于水泥较低.%In this paper, the life cycle assessment method is used to analyze the environmental impact load of ordinary cement mortar and rice husk ash cement mortar during the production and use phase.The research results showed that with the replacement of some cement in rice husk ash mortar, cement dosage decreased, and the consumption of limestone ADP decreased, too.At the same time, rice husk ash was used for waste recycling of agricultural production, and the energy consumption was lower than that of cement.
