#0183;#32;Higher limestone content was limited to avoid failures due to uncontrolled construction procedures in small projects which may threaten the service life of concrete. A series of investigations was therefore carried out to gain experience on the use of Portland limestone cement and to understand the mechanism of thaumasite formation [2], [3], [4], [5], [6], [7] .
#0183;#32;This document is to serve as background technical information for engineers, specifiers, and other concrete technologists on use of limestone in hydraulic cements in amounts up to 15% (focusing on amounts between 5% and 15%). The document also provides supporting data for standardization of limestone blended cements in ASTM C595 and AASHTO M240.
the use of limestone in portland cement: a stateoftheart review Data from published literature and laboratory tests regarding limestone additions to portland cement are reviewed. Emphasis is placed on additions of 5% or less.

The use of limestone in steel making along with iron ore and coke is also quite popular. In its pulverized form, it is used as a soil conditioner to neutralize highly acidic soil. Additionally, the erosional landforms carved out of limestone rock, known as karst in geology, play an important role in natural landscaping.

Quality control of the limestone, limestone portland cement, and concrete is also discussed. In general, the addition of up to 5% limestone does not affect the performance of portland cement. Strengths of cements with limestone can be optimized by grinding to an appropriate particle size distribution.

Portland cement manufacturers have developed a modified formulation of their most important product to respond to growing calls for reducing embodied carbon associated with construction. Portlandlimestone cement (PLC) is a blended cement with a higher limestone content, which results in a product that works the same, measures the same, and performs the same, but with a reduction in carbon footprint of 10%
Portland Stone or Portland Stone Formation is a limestone formation from the Tithonian stage of the Jurassic period quarried on the Isle of Portland, Dorset, England. The quarries are cut in beds of whitegrey limestone separated by chert beds. It has been used extensively as a building stone throughout the British Isles, notably in major public buildings in London such as St Paul''s Cathedral and Buckingham
The calcium carbonate content of limestone rocks has been used from the earliest civilisations, dating back to 14,000 BCE, to its extensive use in modern times. It is a valuable resource that services the needs of a multitude of industries.
