Types of cement - which brand is better to choose ?

cement Properties

This material is not in vain so popular in construction.The fact is that it has excellent performance, and therefore widely established itself among many professionals.In the list of its main features distinguish: frost, water, sulfato and corrosion resistance, high strength, fineness of grinding .It is made in accordance with GOST 5382-91.

considering more characteristics, we can say that frost passes cement capacity to numerous freezing and thawing throughout the year in different climatic conditions.It is calculated depending on the brand.Corrosion resistance passes its ability to resist all kinds of aggressive environmental influences.

Water resistance is reflected in its waterproof characteristics.This means that this material can be used in virtually any environment (and even under water).Sulphate transmits its resistance to solutions containing sulfate ions.This is especially important in the construction of hydraulic structures.Strength properties are entirely dependent on the quality of additives and are reflected in the brand of cement.

Types of cement by the presence of the main mineral

Today there are more than 30 kinds of cements, which are divided by the presence of the main mineral in the product.However, we will look at the most popular and commonly used in construction.

• Portland cement is the main hydraulic binder in construction.It is made by grinding gypsum and clinker portlandtsemntnogo.Plus add all sorts of mineral supplements.It has intensely growing strength during solidification.The tensile strength of the three days can be up to 20-25 MPa.In the future, it is used for the "speed" of construction work, as well as in the production of concrete products.
• Color cement is produced by grinding Portland cement clinker and white adding different pigments.For example, this may include: chromium oxide, ocher, iron ocher.Most often it is used for decorative architectural buildings.They are also used in road construction (in the monumental area).
• hydrophobic cement is produced by mixing gypsum hydrophobising additives and Portland cement clinker.Due to this composition, this material has a higher water absorption and reduced frost resistance.It is because it can be used in harsh environments, as well as in areas with high humidity.
• Slag cement is made by mixing crushed blast furnace slags and additives (perhaps as gypsum and lime).Use this material for the manufacture of concrete and construction mixtures (including cement plaster).If present in the composition of lime addition, the use and the production of autoclaved products.
• Fast setting cement has mineralogical composition, in which there is a maximum clinker and various additives.Use for the manufacture of various concrete structures and in the process of "rapid" development.

In general, the transfer of cement varieties can be very long.Because a small change in composition leads to different characteristics and, hence, the field of application.If there is a question - what to choose cement, it is better to focus on the brand (each has its own class durability and frost).

cement classification marks

In that case, when you try to define - what better cement, it is necessary to find out first for any climate conditions and goals you need one.That is where it will be operated.Then you go to the store and consult with the seller consultant.Or you can make a choice on their own.But again, the question arises - how to choose the right cement, and which parameters you should pay attention to?

Considering the composition of the package is necessary to select two characters «M» or «PC» and «D» .The first mark indicates (in strength and cold resistance), the second additive.

Now we are a little more familiar with the fact, which is cement.If we talk about brands, it is divided into the following : M100 - M600 .The higher the score, the higher the strength parameters.Focus that each can support a load of 100 to 600 kg / cm².That is, it can be concluded that the mark 600 is the strongest.The "D", as has been said, denotes agents.That is, if you see a sign D30, it indicates that the composition contains 30% of additives.It is also important, as it adds products certain properties (on the packaging).
