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 ...

Limestone can be used in pigmentmaking and as a filler for more expensive paints. Paper is also manufactured using limestone. Wood is treated with acid to help break it down, which is then treated with limestone to neutralize the acid and whiten paper. Limestone is also used in dyes and carpeting or other floor coverings, such as protective ...

Limestone powder can cause the thaumasite form of sulfate attack (TSA) of cementbased materials, but the relationship between the content of limestone powder and the degree of TSA is unclear. Hence, six different contents of limestone powder (0%, 5%, 10%, 15%, 30%, and 45%) were used to study the effect of the limestone powder content on the TSA of cementbased materials according to ...

The effects of ordinary limestone powder (OLP) and ultrafine limestone powder (UFLP) on the fluidity, setting time, compressive strength, hydration heat and microstructure of calcium sulfoaluminate cement (CSA) were investigated. The results show that finer limestone powder reduces the fluidity and setting time of CSA.

Limestone powder (LS) has been widely used in cementbased materials; and reportedly, can influence their properties by filler, nucleation, dilution and chemical effects. The action mechanism of LS mainly depends on its particle size and amount. The filler effect of LS refines the microstructure and reduces the porosity of cementbased materials.

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 ...

To further explore the effects of limestone powder (LP) on the hydration of Portland cement as well as the formation and transformation mechanism of calcium carboaluminate phases, the hydration reaction between LP and tricalcium aluminate (C 3 A) is thoroughly studied in this paper. Due to the crucial influence of gypsum on the hydration of C 3 A, two systems are well studied, viz. the C 3 A ...
