Portland cement is the main binder in concrete. Portland cement is made of limestone and shale, which are fired at 1450 ℃ into a synthetic rock called clinker. The clinker is then crushed into powder. When heated, limestone emits carbon dioxide. The reaction of CaCO 3 Cao CO 2 is inevitable
1 is a valuable resource of the earth's crust. It has many uses. It can be used as a building material. It is used to produce cement by heating powdery limestone with clay.
The limestone industry includes companies that produce, mine or mine crushed and crushed limestone. Limestone, commonly known as the most common mineral in the world, is an important raw material for various industries.

In fact, limestone Portland cement has a higher fineness than Portland cement. It is necessary to increase Blaine in the range of 100cm2g to compensate for the strength reduction due to the addition of 1 limestone. 3. Mill type and process system play an important role. Co grinding...
8 the limestone content of cement ranges from 7.5 to 12. According to the recommendations of this study, carbon dioxide emissions per ton of cement production should be reduced by at least 4.5. However, based on further analysis, the actual reduction in CO2 emissions is expected to be higher. This is because
