Thaumasite sulphate attack on self-compacting concrete with limestone filler

Persson, Bertil LU (2007) International Conference on Sustainable Construction Materials and Technologies In Sustainable Construction Materials and Technologies p.461-470
Abstract
The paper deals with durability of Self-Compacting Concrete with limestone filler during Thaumasite Sulphate Attack. For this purpose six concrete with varying amounts of limestone filler, particle size of limestone filler, pressure height during casting and mixing order were studied. One normal concrete (without limestone filler) with vibrator compaction was studied in parallel. In the ongoing experiment the specimen are kept at 5 degrees C in a solution sodium sulphate with circulation with a propeller. The solution is being change every third month. Only low-alkali sulphate resistant cement was used as binder but limestone filler seem to have some effect on the hydration as well. The results show a sudden breakdown after five years due... (More)
The paper deals with durability of Self-Compacting Concrete with limestone filler during Thaumasite Sulphate Attack. For this purpose six concrete with varying amounts of limestone filler, particle size of limestone filler, pressure height during casting and mixing order were studied. One normal concrete (without limestone filler) with vibrator compaction was studied in parallel. In the ongoing experiment the specimen are kept at 5 degrees C in a solution sodium sulphate with circulation with a propeller. The solution is being change every third month. Only low-alkali sulphate resistant cement was used as binder but limestone filler seem to have some effect on the hydration as well. The results show a sudden breakdown after five years due to Thaumasite Sulphate Attack similar to salt-frost scaling of all concrete with limestone filler. The normal concrete without limestone filler is still performing well after six years in the very same basin as the concrete with limestone filler. The ongoing research was performed at Lund Institute of Technology, Lund, Sweden, 2000-2006. (Less)
