In 2011, Mexico produced 35.4 million tons of cement, 3% more than a year earlier. The first cement-making plant was built in Mexico in 1906, a few years after cement was first officially approved for use in the construction sector. Cement demand grew only slowly prior to a spate of public infrastructure projects in the mid 1940s.
