Latin Americas largest cement company will invest US$187 million to increase cement production capacity in the DR. The investment reflects a recognition on the part of the Mexican industrial giant, CEMEX, that the countrys building boom is likely to continue for some time. The planned investment will allow the DR to become totally self-sufficient in cement production, and to become a net exporter as well. Cemex has already commenced construction of a new vertical mill to produce clinker, thought to be the worlds largest of its kind. When completed CEMEX installations will allow for annual production of 2.4 million tons, up from current capacity of 600,000 tons.
