Abstract

The improvement of concrete workability can provide a considerable reduction of production expenses and also leads to significant improvement of construction quality. This paper reports on the development of self-consolidating concrete (SCC) based on local materials, such as metakaolin (MK) and aggregate fines. The use of metakaolin in SCC is found to be very promising, due to its ability to increase the flowability and segregation resistance of concrete mixtures. Furthermore, due to pozzolanic properties, the application of MK provides an improvement of concrete microstructure, strength and durability. The proposed SCC design includes the optimization of aggregates and combined aggregate-binder powders to target 0.45- and 0.3- power particle size distributions, respectively.
