Cement is an important part of building materials, and in the market common cement, common to have P type and M type cement. So what is the difference between these two kinds of cement? below we will introduce in detail for you. The difference between

cement type P and M is mainly reflected in the following aspects:

1. raw material composition
P type cement and M type cement raw material composition is different. P-type cement mainly uses slag, mine slag, limestone and sandstone and other raw materials; M-type cement mainly uses limestone, clay, gypsum and other raw materials. Therefore, there are some differences in the source of raw materials and the proportion of ingredients.

2 compressive strength
P-type cement and M-type cement in the compressive strength is also different. P-type cement has high compressive strength and is suitable for projects with high compressive capacity requirements, while M-type cement has relatively low compressive strength and is more suitable for projects with low compressive requirements.

3. Scope of use
Due to the differences in raw material composition and compressive strength between P-type cement and M-type cement, their scope of application is also different. Generally speaking, P-type cement is suitable for large-scale water conservancy, hydropower, highways and bridges and other projects with high strength requirements; while M-type cement is more suitable for some general housing construction, decoration and other projects.

4. Construction technology
in the construction technology, the use requirements and construction technology of P type cement and M type cement will be slightly different. Therefore, when choosing cement, construction technology and technical requirements are also factors to be considered.

In general, there are certain differences between P-type cement and M-type cement in terms of raw material composition, compressive strength, scope of use and construction technology. Consumers need to choose according to specific engineering needs. I hope this article will help you when choosing a cement model.
