Abstract
One-dimensional compression tests were performed to investigate compression characteristics of sludge cake used as a construction material. The sludge cake is dewatering product of dredged sludge from the bottom of a lake. The test results show following compression characteristics. (1) For the undisturbed samples, e-log p curves show compressibility of overconsolidated clay ordinatily observed. (2) For the disturbed samples, there observed compressibility close to that of ordinary normally consolidated clay. (3) For the recompressed samples, there observed two turning points on e-log p curve. The compression presures(p(c1) and p(c2)) at those points for the unsubmerged tests have a linear correlation with the recompression pressure(p(s)). The submerged tests give very small values of p(c1) and p(c2) compared with the case of unsubmerged test. (4) For the recompressed samples, the first compression index(C(c1)) after p(c) has a linear correlation with the initial void ratio(e(0)), and the second compression index(C(c2)) shows almost constant value.
