Several attempts have been made in North Dakota, starting in the early 1890s, to produce natural cement. From 1899 to 1909, a natural cement plant operated west of the town of Concrete in eastern Cavalier County. The plant baked high lime shales from the Niobrara Formation in kilns and ground and packaged the resulting natural cement.

Limestone functions as a supplementary cementing material when it is finely ground with clinker into portland cement. Limestone quality should have at least 75% calcium carbonate by mass, a clay content less than 1.2% by mass, and an organic content less than 0.2% by mass.

The tested material is a good quality and purity. From the chemical composition point of view the tested limestone has a high content of about 96% CaCO3, with small amount of clay minerals and with traces of quartz, which corresponds to the medium purity limestone. It was confirmed, that this limestone is suitable for cement production.

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a .

Slabs can be sold as they are or can be transformed into finished products to the size required.The stone materials constitute up to 70% of the weight of the finished product and are in general either siliceous (quartz, quartzite, granite, porphyry, sand, etc.) or calcareous (marble, limestone, dolomite, etc.) with sizes ranging up to 6-8 mm.

To date, however, few studies [7, 10] have gone beyond 50:50 volumetric ratios of limestone or quartz:cement and their focus has been much more on analyzing calorimetry results and/or compressive strengths than rheology and setting times. In the case of limestone filler, it has been suggested that its influence on setting is two-fold.

In cement plant, most of the material need to be broken, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount of raw material in cement production, after mining the size of limestone is large, with high hardness, so the limestone crushing plays a more important role in cement plant.

Such clays are widely distributed and, as clay is often one of the raw materials for cement production, may even be available in existing quarries of cement plants. • Blended cement containing calcined clay and limestone can be used across a range of applications similar to other general use cement types. •

Establishing new limestone quarries and cement plants in the United States is a slow process, and supply shortfalls require time to correct. It takes about 2 years to build a new cement plant, and the permitting process can take much longer - 8 to 10 years.
