Applicability of Controlled Low-Strength Materials with Incinerated Sewage Sludge Ash and Crushed-Stone Powder
This paper discusses the applicability of new controlled low-strength materials (CLSM) that include incinerated sewage sludge ash. The incinerated sewage sludge ash was used as a replacement for fly ash, which is the main component of CLSM. A dust powder made during crushed-stone production was used as a fine aggregate. This new type of green CLSM is a promising sustainable cementitious material with the capability to reduce CO2 emissions. The test results show that adequate strength development and reasonable flowability can be achieved if the mixture proportion is carefully designed. The leachate characteristics of the new CLSM are evaluated in this paper, and the test results show acceptable leachate levels. The test results also confirm that a wide range of municipal solid wastes could be used as materials in the new green CLSM. Finally, backfill construction was conducted with this new CLSM, and the excellent performance was confirmed.
