In common Portland cement, particles having a size range from 3 to 35 μm are preferred for all the above-mentioned reasons. The common production indicator of optimal cement clinker grinding is the mass fraction of the size distribution passing through a 0.09-mm sieve. This should range from 90% to 97% of the distribution (Sauman, 1993).

The majority of the cementitious binder used in concrete is portland cement clinker, the manufacture of which is an energy-intensive process. Approximately 2% of world energy is spent in this process [1]. Considering the annual production of 1.6 billion tonnes of portland cement, the cement industry itself is responsible for 7% of the total CO 2

The benefits of using limestone as a partial replacement of Portland cement (PC) are well established in the literature. Economic and environmental advantages by reducing CO 2 emissions are well known. This paper describes the influence of the producing method (intergrinding or separate grinding) and particle size distribution on properties of Portland-limestone cements (PLC).

In 2019, U.S. Portland cement production was 86 million tons and masonry cement production 2.4 million tons. Cement was produced at 96 plants in 34 States, and at 2 plants in Puerto Rico.
