Abstract

Highlights: The effects of limestone powder (LS) depends on its particle size and content. Using LS to replace fine aggregate improves the properties of concrete. Using LS to replace cement reduces the properties of the concrete. Abstract: Limestone powder (LS) is one of the mineral materials in concrete due to its wide availability and low cost. This paper discusses effects of LS on the workability, setting time, shrinkage, mechanical properties and durability of concrete. Such effects are mainly influenced by many factors, including the particle size and content of LS, the polymorph of calcium carbonate and synergetic effect between LS and alumina-rich supplementary cementitious materials (SCMs). In general, incorporating LS, as cement paste replacement or in the form of fine aggregate, improves the properties of concrete. Whereas, when LS is incorporated into concrete to replace cement, effects of LS on the properties of concrete depend on its particle size and content. In the end, some further research needs are also suggested.
