Chemical Composition Of Marble Dust

Marble dust can be used as an admixture in concrete so that strength of the concrete can be increased.

Chemical composition of marble dust.

Table 6 2 presents the chemical compositions of the wmps were used in many different studies. The chemical analysis of portland cement incorporating 5 wt of the marble dust waste illustrates that the cement is still keeping a high c 3 a content 6 96. Geologists use the term marble to refer to metamorphosed limestone. Marble is commonly used for sculpture and as a building material.

The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. 38 42 lime cao 20 25 silica sio2 2 4 alumina al2o3 1 5 2 5 various oxides nao and mgo and 30 32. However stonemasons use the term more broadly to encompass un metamorphosed limestone.

We can reduced the environmental pollution by utilizing this marble dust. Chemical composition of opc compared to the composition of the cement incorporating 5 marble dust waste mdw. Marble may be foliated. Marble dust powder is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite.
