The discard and landfill of by-product gypsum cause significant environmental problems. About 100–280 million tons of phosphogypsum and a large amount of waste plasterboard are produced every year in the world, but the utilization rate of phosphogypsum is about 10%. Most by-product gypsum is directly landfilled or discarded without treatment, only a small amount is recycled and reused. In the past decades, by-product gypsum has been used in different geotechnical engineering applications, such as subgrade filler, soft soil stabilization, expansive soil treatment, etc. This paper presents a comprehensive review of the engineering and environmental properties of recycled gypsum stabilized soil, which includes compaction characteristics, consistency, strength, deformation, compression, shear, expansion properties, and durability. Meanwhile, the environmental effect is also analyzed. In summary, the recycled gypsum in geotechnical engineering application is promising.

岩土工程再生石膏稳定土的工程性质及环境效应评价:综合评述

副产品石膏的丢弃和填埋会造成严重的环境问题。全世界每年产生约100-2.8亿吨磷石膏和大量废石膏板,但磷石膏的利用率约为10%。大部分副产石膏未经处理直接填埋或丢弃,只有少量回收再利用。在过去的几十年中,副产石膏已被用于不同的岩土工程应用,如路基填料、软土稳定、膨胀土处理等。 本文全面回顾了再生石膏稳定土的工程和环境特性。 ,包括压实特性、一致性、强度、变形、压缩、剪切、膨胀特性和耐久性。同时,还分析了环境影响。综上所述,再生石膏在岩土工程中的应用前景广阔。
