水泥-工业固废协同固化淤泥耐久性能评价
Durability Evaluation of Cement Industrial Solid Waste Co Solidification Sludge
摘要
Abstract
To evaluate the durability of cement-industrial solid waste solidified sludge,cyclic wet-dry and freeze-thaw tests were conducted to reveal the physical and mechanical properties of solidified sludge under complex exter-nal climate condition.The results showed that the compressive strength of cement-solid waste solidified sludge was better than that of pure cement group.The 28-day curing compressive strength of cement,curing agent Ⅰ and curing agent Ⅱ solidified samples were 539.3,542.1 and 546.1 kPa,respectively,while the 60-day curing compressive strength reached 744.3,865.6 and 904.1 kPa.As the number of wet-dry cycle in-creases,the compressive strength of solidified sludge slightly increases during the first wet-dry cycle and con-tinues to decrease thereafter.After 11 wet-dry cycles,the mass loss is 10.2%,9.7%and 9.0%,respectively,and the strength loss is 41.1%,39.1%and 30.9%.As the cyclic freeze-thaw number increases,the compres-sive strength and mass of solidified samples of pure cement,curing agent Ⅰ and curing agent Ⅱ gradually de-crease overall,after 15 freeze-thaw cycle,with strength loss reaching 32.7%,22.0%and 16.0%and mass loss of 23.8%,16.0%and 17.9%.关键词
