One of the most significant methods of advanced technology for mining, the rock massif is employing expansive\udmortar for cutting of Rock. Furthermore, the entire expansive mortar commercialized in the Brazilian domestic market\udare imported, as well as those in industrialized country. Both have components from the external market. The aim of this\udwork is to develop expansive mortar with raw materials that have regional and pressure sufficient to remove the rocks\udof granite and marble type expansion. For this, expansive grout formulations using calcium oxide, calcium carbonate,\udcarboxymethylcellulose are used - CMC (Portland) cement, and from the chemical analysis by means of thermal analysis,\udX-ray diffraction and laser granulometry compared the results with a commercial mortar. The results indicated that the\udformulations showed characteristics similar to the commercial mortar
