Carbonation of self compacting concrete
Self compacting concrete (SCC) is a new kind of concrete that doesn 't need any compaction. The two essential properties of SCC are a high flowability and a high segregation resistance obtained by a large amount of fine particles and the use of superplasticizers. It is known that the pore structure of SCC is differing from the pore structure of traditional concrete. Due to the addition of a high amount of fine particles, the internal material structure shows some resemblance with high performance concrete. Many research programmes have already been released concerning the fresh properties of SCC, but only few information is known about the durability of SCC. This project includes laboratory studies of carbonation of 7 SCC and 2 traditional concretes. These concretes were either stored permanently in a carbonation room at 20 deg C, 60% R.H. and 10% CO2 or alternately one week in the carbonation room and one week immersed in water. A constant amount of cementitious materials ( cement and filler), even as a constant amount of water, sand and gravel was considered. The influence of the amount and type of cement and filler is studied. The results of this experimental study are compared with models found in literature predicting the depth of carbonation for traditional concrete.
