This paper considers the influence of rock and mineral properties on the behaviour of marble in claddings. A selection of results is presented, illustrating the influence of properties like mineralogy, grain size and boundaries, preferred orientation and pore structure. Of the intrinsic parameters, ...

The term“marble“finds its origins in the Greek word“marmaros,”translating to“shining stone.”Geologically, marble is a metamorphic rock that emerges from the transformation of limestone through extreme heat and pressure over millions of years. ...
Detergents don’t produce soap scum the way soap does because they don’t react as readily with hard water minerals and have a higher pH than soap, so they tend to work better and have fewer issues in water that has a high mineral content. ...
An important basis to determine the dolomite is less than 50% dolomite rock mineral content. In addition, dolomite is porous stone. Chemical composition of trapped dolomite is not sensitive to acidic substances, dolomite has better weatherability. Generally speaking, these two methods are often used...
