No one will argue with the fact that without a modern cement construction industry do not have any way he can.Without it will not be possible to construct a single building, will not lay any road.Plants for the production of this remarkable material is produced every year more and more products, which instantly disperses.
Each builder knows that the need for the construction of houses cement-sand mixture on the preparation of which we'll talk today.Of course, this topic is not very easy, because before you start you need to purchase at least a basic knowledge of the existing brands of cement and characteristics of each of them.
Considering that guests on each of them provides different strength characteristics, all varieties of cement are assigned serial numbers.The most commonly used grade 200, 300, as well as all kinds of 400-600.The number more, the particular variety is ideal for a foundation of concrete.Naturally, the cement-sand mixture can be obtained from the "junior" marks.
most common and widely used Portland cement.Unfortunately, sometimes there are situations when it can not meet all your requirements.That is why in some cases choosing sulfate, hydrophobic or bystrozastyvayuschy type.However, there are many more specialized species, which are often of interest only to professionals.
Forms solutions
- Rarely used oily cement-sand mixture, which included a lot of binder.She quickly freezes, but not very durable because of the tendency to crack.
- The most frequently used conventional cement slurry, in which the proportions of all the components are ideal.He freezes rather slowly, but its life above all praise.
- Failure to follow the technology of the novices often get so-called lean solution binders in which almost none.This mixture is cured in principle.
dealt with the basic concepts, we consider some special types of cement mortars and learn about the methods of their preparation.
mixing methods
How to prepare cement-sand mixture?If you are going to build something big tent, you should know the answer to this question.In many ways, the process of preparation is similar to the technology to produce mortar.Required to comply with a certain proportion: taken cement and sand in 1: 3 ratio, water is added and the mixture was thoroughly stirred.Constantly monitor the consistency: if the mass of watery, it is necessary to add cement, if "dryish", then water is added and the filler.
However, for grouting of cracks and joints builders almost never used the cement-sand mixture.Standard requires the construction of a cement-lime mortar.
cement-lime mixture
its technology is no different, but instead of water used "thin" solution of lime.Such a composition is not only ideal as grouts, but also can be successfully used as a mortar for the walls and even the ceiling.
In conclusion we can say that there is no construction wherever used cement-sand mixture.Its price varies greatly, depending on the components used and the manufacturer of cement, so there's all strictly individually.
