Each year, millions of tons of by-product fines are produced during the crushing and processing of limestone and dolomite quarried in the United States. Similarly, a large amount of lime sludge is produced in the United States from water treatment plants that use lime softening to reduce the calcium and magnesium hardness of the source water.

The content of aggregate between 9.5 mm and 13.2 mm increases in basalt mixture while decreases in limestone mixture. The increase of < 4.75 mm aggregate content in basalt mixture is far less than that in limestone mixture. It can be concluded that the crushing degree of limestone in compaction is worse than that of basalt.

Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate. When the rock contains 30 to 45 percent magnesium carbonate, it is referred to as dolomite, or dolomitic limestone. Lime can also be

limestone sample is strongly influenced by compaction and particle size distribution. The effective porosity decreases with the increase in compaction and decrease in larger particle size, respectively. Particle crushing during com-paction is a main cause of size 0–2.5 mm materials, whereas some fine particles are washed away due to the

The data from limestone particle crushing tests once again proves that the Weibull distribution is a good tool for describing the crushing strength of particles. The Weibull modulus m does not have an obvious relationship with the particle size d and the particles with sizes ranging from 10 to 240 mm have an m between 2.017 and 2.986.

Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
