Abstract:

There is an extensive presence of kaolinite clay (KC) in different locations in Sudan with the appropriate composition to match OPC when converted to Meta-kaolin (MK). The very promising structural results affirm that it has a great potential to be a suitable alternative for cement in normal concrete mixtures. This study aimed to extend MK's utilisation in different forms of concrete mixtures. This paper portrays the results for investigating the potentiality of using MK to produce self-compacting concrete. MK was prepared, tested to verify its pozzolanicity then included in different proportions in the mix design for the SCC sample. Three trials were prepared, and fresh and hardened properties were investigated. Fresh concrete properties provided evidence that the obtained mix is appropriate for unreinforced or slightly reinforced structures, use in vertical applications in very congested structures and for many normal applications. The 28- day compressive strength results exceeded 40MPa confirming its appropriateness as a filler to produce SCC. As an abundantly available material in Sudan, these results suggest that MK is a good alternative to be used to produce SCC in Sudan.
