Cement Industry in USA
Of the 50 states in USA, more than 30 states have cement producing plants. Of the three types of cement production plants in the USA, there are 96 integrated cement plants and 8 grinding plants.
For those who are new to cement industry terms, an integrated cement plant is a factory where 2 processes take place – clinkerization and grinding.
Clinkerization involves changing limestone to clinkers. Grinding involves crushing the clinkers to make cement.
A variety of cement is manufactured at these integrated cement plants. These are:
- Portland cement
- White Cement
- Blended Cement
- Slag Cement
- Masonry cement
Of the above types of cement, Portland cement is used for making concrete. Hence, production of Portland cement is quite high when compared to other types of cement.
Concrete and cement are two different construction materials. Concrete is made by mixing cement, sand, gravel and water.

Wrap up – Largest Cement Manufacturers in USA
There are very few domestic players in this list of cement companies in USA. There are two main reasons for this:
#1. Economic slowdown
#2. Environmental regulations
Firstly, economic slowdown due to the recession of 2008 has led to an overall low consumption of cement. This means cement companies in America are producing cement at less than full capacity or not producing at all.
Secondly, strict environmental regulations of EPA and NESHAP led to closure of many cement factories.
In such adverse conditions small cement companies in USA were unable to sustain themselves and only big multinationals could survive leading to mergers and acquisitions.
