Fine limestone is commonly included in Portland cement by intergrinding, resulting in an optimal particle size distribution of the modified cement. In other applications, limestone powder is added separately from cement, for producing more stable and robust mixes, especially selfcompacting concrete.

Among the various inert fillers, limestone fines (LF) may be a good choice. LF is a byproduct of the limestone quarry industry, which, if not used, has to be disposed of as waste causing environmental problems. In fact, LF has been used in concrete for many years.

Understanding Limestone in Cement Concrete Construction

Understanding Limestone in Cement Concrete Construction

The history of limestone in cement is a little checkered, and as a result, there is some controversy in this decision, along with some confusion and concern. Here in the it is long past when finely ground limestone was added to cement to make "adulterated" cement. Although this remains a problem, mainly in the third world where cement ...

For these mixtures, the water volume fraction (content) was maintained constant and cement was replaced by the limestone or silica powder at a 1:1 ratio on a volume basis, producing variable watertopowder ratios ( w/p) on a mass basis. Systems varying from 100 % OPC to 5 % OPC:95 % LS were examined. In addition, mixtures with SA were prepared ...

The replacement of traditional cement with high clinker content should be achieved quickly to lower the carbon footprint of mortar and concrete. Cement is responsible for about 70% of the carbon footprint of cementitious materials. Current research suggests that the use of limestone and metakaolin or calcined clay could replace the current four gigatons of clinker produced.

Longterm properties of concrete containing limestone powder

Longterm properties of concrete containing limestone powder

Plain cement concrete (employed as reference) and three concretes containing limestone powder (replacement ratios of 10, 20, and 30%) were designed. The compressive strengths of the four concretes were close to each other by adjusting the water to binder ratios. The longterm (as long as 5 years) properties of hardened paste and concrete were determined under the condition of equal 28day ...
