Cement is an indispensable thing in construction. Many people who are new to decoration do not know what the cement label means. When it comes to buying cement, they are confused. When they see the cement label, they have no idea. So said. What exactly does cement labeling mean? Is the higher the cement labeling, the better? The following editor will introduce to you the issue of cement labeling.

1. What do cement labels mean?

There are different labels written on cement packaging bags, such as 400, 500, etc. These numbers have different meanings. Usually we all know that building bridges and roads must be very strong, and high-strength cement is needed. As the saying goes, there is no need to kill a chicken with a bull's knives. There is no need for such high-strength cement to build houses, factories and the like. Depending on the construction needs of different buildings, the grade of cement used will also be different. The cement label is the grade mark of the cement. The main information contained in the cement label is:

1. The cement label includes the strength of the cement after solidification

This strength includes the compressive capacity and tensile strength of the cement after solidification. affordability. The higher the cement grade, the greater the two strength values. On the contrary, the smaller it is.

2. The cement label includes the speed of cement solidification

The cement label also means the speed of cement solidification. General emergency projects and underwater projects, such as sewers, bridge piers and other buildings, must require a short setting time. It is better to use fast-hardening cement such as No. 700 and 800. However, construction projects such as walls and floors do not have such fast setting time requirements, so cement with a slower setting speed is needed.

2. Is the higher the cement grade, the better?

Seeing this, some people may ask, since the higher the cement grade, the greater the strength and the shorter the solidification time. When renovating, is the higher the grade of cement, the better? Many owners also saw "325 cement" on the list issued by the decoration company when renovating, and wondered whether the grade was too low. Not reliable. Senior industry insiders said that in fact, the higher the cement grade, the better. When choosing cement with different grades, in addition to the price factor, you must also consider the use of the cement.

1. Price. Cement with a larger number has better compressive capacity and tensile strength, and the construction requirements are more complex, and naturally, the price is higher. When renovating, it is necessary to budget the funds well and spend the money wisely.

2. Purpose. Each cement grade has its own scope of application, and it cannot simply be understood that higher is better. For example, 525 cement is not suitable for building walls, but is more used for laying floor slabs. Although 525 cement is stronger, it dries faster. Especially in the current hot summer and high temperature environment, if it is used to build walls, the probability of wall cracking will be higher; on the other hand, the walls built will not bear stress. wall, so 325 or 425 cement can meet the needs of early decoration.

Understanding the problem of cement marking, we will have a better understanding of the decoration of our own home, and we can avoid misleading us by the decoration company.
