There are several reasons why the Estado de Mexico (a state, not the country) is important not only at the national level but also because of its intrinsic relationship with Mexico City since 59 of its municipalities are considered part of the Metropolitan Area of the Valley of Mexico. In this area, there are a large number of industrial plants. In addition, it houses some of the most visited archaeological sites such as Teotihuacán, Tetzuco, Azcapotzalco, Chalco, and Amaquemecan.

Concrete, a material commonly used in the construction industry, is made of a binder combined with aggregates (or gravels), water, and certain additives. Its origins reach back as far as Ancient Egypt, when the construction of large structures created the need for a new kind of material: one which was liquid, featured properties of natural stones, could be molded, and communicated a sense of nobility and grandeur.
