Abstract

Limestone powder is a powdery material that is made of limestone with a certain purity and ground to a specified fineness grade. Due to its abundant resources, wide distribution and convenient processing, limestone powder is a cheap and easy-to-obtain material. Limestone has a long history being utilized as a supplementary cementitious material, mainly for the production of ordinary Portland cement and limestone composite cement. The influences of limestone as a mineral admixture on the performance of cement composites has become a popular theme in recent years, and it is mainly used in the production of high-fluidity cement-based materials and concretes in the areas where high-quality mineral admixtures are lacking. Using limestone powder for blended cements can reduce concrete carbon emissions by about 15% and save about 10% of cement clinker. Therefore, the researches focusing on high-volume limestone blended cement-based materials are of significant importance to realize the sustainable development of the cement concrete industry and ensure the green construction of engineering structures towards carbon neutrality. This chapter overviewed the research progress of high-volume limestone blended cement-based materials from the aspects of limestone action mechanisms, materials microstructure, fresh-state behavior, early-age performance, and long-term durability.
