Mainly because its aesthetic characteristics it has been widely used as building and ornamental stone. “Verde di Prato” most common local name in Tuscany to refer this type rock, historically quarried area for many centuries large number monuments region.

In the meantime it may be concluded that: (1) The proteins edestin, excelsin and hemoglobin crystallize with water of crystallization, which is very readily lost. The hand pattern previously described as common to these and other proteins is produced by apparently amorphous materials resulting from the efflorescence of the crystalline compounds. (2) If care is taken to prevent the decomposition...

It is an effective method to prepare geopolymer with recycled brick and concrete fine powder (RP) slag as main materials for the resource utilization of construction waste. However, its hydration products have large drying shrinkage high efflorescence risk under normal curing conditions. Until now, durability powder–slag-based (RPSG) has not been well documented, such efflorescence. In this stu...
