对上海不同地区及不同深度处的深基坑土进行取样,测试了其化学成分、矿物成分、含砂率和塑性指数等性能,并分析了其代替黏土生产烧结制品的可行性.结果表明,上海地区深基坑土含水率较高,颗粒细,可塑性好,粘度大,并且主要由石英,高岭土和云母等矿物组成,其化学成分在烧结制品适宜范围内,可代替黏土在烧结制品中应用.不同深度处深基坑土含砂量不同,应进行预处理,并控制其杂质及含砂率.

The clay samples from different depth foundation pits of different regions in Shanghai are tested on its chemical composition, mineral composition, sand content and plasticity index. The paper analyses the feasibility of the clay for producing fired product. The test results show that the clay has high moisture content, fine particles, good plasticity and viscosity, and it mainly composes of quartz, kaolin and mica mineral within the range of suitable chemical composition of the fired products, thus the clay can be used in fired products.
