Cement & ndash; this is one of the most common and important building materials, without which modern construction would not do. As a component, it is used for making various solutions and mixtures. All buildings erected over the past 200 years, created with his participation. What is made from cement, what are the types and where are they used? Let's try to answer these questions.
The Source material is a dry powder substance of artificial origin. It is obtained by grinding and mixing clinker, gypsum, as well as various fillers and additives. However, it is the clinker is a mixture of. It is obtained by crushing and firing limestone, clay and various mineral components. Depending on the percentage of the data elements, properties and use of cement will be different.
What make of cement in the construction based on a chemical reaction in which the powder when in contact with water turns into a paste-like mixture. In the future, under certain physico-chemical processes converts the liquid mixture into a solid. As a result cement mixture acquires a solid structure.
The Mention made of cement, primarily to highlight the ready-mixed concrete, concrete products created in the factory or at the construction site. Also produces asbestos cement materials plaster, masonry and other construction mixtures and solutions.
At the moment there are about 40 types of cement, each of which is used to create a particular design. Consider some of the variety.
This is the most common type used for the manufacture of precast concrete products. It is made of high quality concrete, which in construction are used to create load-bearing elements of buildings and structures. If you believe the statistics, it accounts for about 60% of the total produced types of cement for the year. Moreover, Portland cement clinker – this is the base for the manufacture of other varieties of cement. Supporting columns, walls and concrete slabs can be manufactured from this material.
It is Obvious that ordinary Portland cement is grey, as in its composition contains a large amount of iron and manganese. But if the content of these oxides in clinker will be insignificant, and when the production used white clay, the Portland cement mixture becomes light white shade. It is not used to create a durable load-bearing structures. It is most often used for decorative and finishing works.
A Feature of the production of the material is that the raw material is fired in a special ash-free fuel.
As for the colored raw material, then it is made on the basis of white Portland cement. It simply added a small amount of gypsum and special color filler. It is easy to guess that it is used for decorative purposes, in particular for the production of non-ferrous surfaces, performing textural elements and components, the manufacture of coating materials.
This belongs to the group of hydraulic binders. It is made by crushing and subsequent grinding Portland cement clinker, blast furnace slag and gypsum cement. It is known that cement made from this type of different building blocks, construction dry mixes and plaster base.
This material also belongs to the group of hydraulic binders. He has one unlike other materials that shrink in volume and weight. Expanding cement does not shrink. Furthermore, hydration process and strength development accompanied by expansion of volume, especially in the first stage after setting.
This type of cement is used for making injection and repair mixes, which are used in major repairs of damaged concrete structures.
Given the properties of this material, it is possible to do anything. Nothing prevents to create a wall panel or a cement-sand tiles based on it. Virtually any correct or even incorrect forms of building elements can be created in factories and even on construction sites.
This versatile material is a Foundation of any building structure.The building is always start to build from the Foundation, the basis of which lies necessarily high strength concrete is created from cement mixture. Later in the course of construction used reinforced concrete structural elements, and complete the construction of coverings of the roof, which can be a cement-sand tiles. Lately it has become very popular. Also and decorative finishing work is often applied using cement mortar.
Consequently, in modern construction, the value of this material cannot be overemphasized. This is the most cheap, convenient and durable item, the use of which is justified on 100 %.
