Indian Concrete JournalSummary: This article reviews our current understanding of the efficient and durable usage of Limestone Calcined Clay Cement (or LC3 in short). In around a decade, this cement has gone from the laboratory to the field and is on the verge of becoming a commercially available product. However, given that the properties of this cement are different from those of conventional cements, this article compares the design and performance of concrete using conventional cements with those using LC3. It has been seen that while the water demand of concretes with LC3 is relatively higher, the cement imparts higher cohesion. It has also been observed that the strength of concretes with LC3 develop faster than concretes with fly ash. While the transport of water has been seen to be comparatively slower in LC3, carbonation is seen to be faster. However, moisture transport is seen to increase in carbonated concrete. The rate of corrosion is, therefore, likely to be different from other cements and to depend on a multitude of factors. LC3was also seen to be more sensitive to temperature than the other cements. This article discusses some important findings regarding the performance of concretes produced using LC3.
