Indian Concrete Journal - ICJSummary: Limestone calcined clay cement (LC3) is a mixture of clinker, calcined clay, limestone powder, and gypsum. The special blend of ingredients gives unique characteristics to this cement, which leads to improved performance of the concrete apart from lowering the sustainability impact as compared to ordinary Portland cement (OPC) concrete. While the durability in chloride environments is a major plus of LC3, there are issues with the achievement of workability and its retention. Different strategies can be employed to improve the workability characteristics of such systems. This paper describes the versatility of concrete with LC3 using three case studies – (i) achievement of durability in chloride environment even with poor quality control during the concreting process, (ii) use of limestone calcined clay binder in combination with Portland pozzolana cement (PPC) for the manufacture of tetrapods for breakwater purpose, and (iii) use of LC3 in 3D printed concrete that results in taking advantage of its difficult rheology.
