ABSTRACT
Nano technology produce new materials with new properties in compared with the known material (Bulk) as the nano calcium hydroxide became to be the successful consolidation material as it converted into calcium carbonate which connected the insidious structure together. There is no doubt that nano materials have many advantages as they are pure and less weight, bright, without salts and impurities. Currently in this paper a comparison is made between natural Calcium carbonate, nano Calcium carbonate and the converted calcium hydroxide in to calcium carbonate (new born) regarding appearance, color, weight, porosity, absorption, the hardness of samples, the bursting strength to detect the advantages of the nano materials, and the major reason behind the great success of nano lime which converted in to calcium carbonate after application.
