摘    要:目前在水泥系深层搅拌桩施工中 ,一般采用熟石膏 ,掺量为2 %(占水泥重) ,但试验证明 ,在水泥土中掺加生石膏后 ,水泥土的早期、中期和后期强度均可提高 ,尤其可大幅度地提高早期强度 ,生石膏的最佳掺量为3.6%~7.1%(占水泥重)。

关 键 词:生石膏  水泥系  深层搅拌法  最佳掺量

Abstract:Currently in construction of mixed cement piling,it is usually mixed with 2% calcined gypsum(of cement weight).It is proved,however,if mixed with plaster stone the early,medium and after strength of the cement soil can be improved,especially improved drastically for the early strength.The optimum percentage of the additive ranges from 3.6% to 7.1% (of cement weight).
Keywords:plaster stone  cement deep mixing method  optimum quantity to be added
