Little formal work has been done to analyze the behavior of the Mexican cement industry in detail. The most germane studies have focused on analyzing the overall nature of the industry (Avalos and Schatan, 2003; Kumakan and Martínez, 2008), analyzing the efficient use of energy in production (Sterner, 1990), the market structure by which the industry …
Gypsum prevents Flash Setting of cement during manufacturing. It retards the setting time of cement. Allows a longer working time for mixing, transporting and placing.

The nominal cement production capacity in Mexico is 60Mt/yr according to the Global Cement Directory 2023. Yet, the actual production capacity has been reported in local press as being 42Mt/yr, lower than the annual cement production of 43.9Mt in 2022. In February 2023 it was reported that the Mexican government was taking steps to …
White cement had a relatively small tariff of 22 cents per ton in the U.S. and 54.25 cents in Canada. Mexico did have a 10 percent duty on most cement products and placed cement in category B, such that all goods were made duty-free on January 1, 1998.
In contrast, cement boards are far more resistant to moisture and have a lower potential for the growth of molds and mildew. 2. Strength and Impact Resistance: When compared to gypsum boards, cement boards have superior strength and resistance to impacts. Gypsum boards are more vulnerable to breakdown and denting from strong …
major industry. As with construction spending, cement consumption has declined in tandem with the nation economic downturn over the past several years (see Figure 2). Still, with 167 cement kilns and 116 clinker producing plants located across the United States, the Portland cement industry has a huge impact on the national economy.

Walls: For most walls a board that is 10mm to 12mm is common. For walls requiring greater fire and impact resistance use a board that is 15mm to 20mm thick. For walls that have continuous backing, cement or rigid insulation, a thinner board can be used. This is important when weight is a concern.
