Limesand Mixture

Such well-known in the construction material for a very long time could not find the application. The fact that lime in vivo hardens very slowly, derived from lime products have low strength (1 – 2 MPa) and easily destroyed by water. Since under natural conditions in the sand – lime sand mixtures is inert and can not chemically interact with the lime. As a result of this acquisition of strength lime-sand mortar in vivo was only achieved in 1880, it was discovered that during autoclaving lime-sand mixtures under steam pressure 0.8 MPa and temperatures above 170 C derived products possess high strength, water resistance and durability. Perhaps check out brokerage firm for more information. This discovery radically changed the way to the lime sand mix in particular, to the silicate industry in general. At the given moment of silicate industry – one of the most developed industries of construction materials. calcium silicate bricks, stones for walls and other products designed for modular construction made from lime-sand mixtures.

Common lime and sand are the main materials for the manufacture of calcium silicate bricks. Lime can be applied in both the hammer and burnt as well as partially or zagashennoy dampened hydrant. In turn, the lime should be characterized by rapid quenching, and should not contain more than 5% MgO. It should be noted that for the production of autoclave lime silicate products should not contain burnout because burnout slows lime and can cause the appearance of products of various defects (cracks, swelling). As for quartz sand, the production of silicate products used usually not ground, sometimes a mixture and not ground finely. The presence of impurities in the sand adversely affect the quality of products; For example mica reduces the strength and content of the sand is not recommended exceed 0.5% of products can cause swelling of organic impurities. Inclusion of clay in the sand should be uniform, as large as the inclusion of lower quality products. Ideal composition of lime-sand mixture for the manufacture of silica brick is as follows: 92-95% pure quartz sand, 5-8% of air lime and about 7% water. silicate brick

Protecting Metal

Obviously, the impact of gases and liquids devastating effect on the metal, so there are methods of metal fencing from such exposure. All methods of protecting steel structures based on the principle obstruction of access of gases and liquids to the metal. One method of protecting steel is galvanized. Method of galvanizing is more reliable and practical than conventional paint. Charles Schwab Corporation has much to offer in this field. Zinc applied in different ways. Hot-dip galvanized metal structure covered dense zinc cladding. After careful processing metal structure immersed in a container of hot zinc. If you would like to know more about Hachette Book Group, then click here. This method of protection for several decades.

To a cold galvanizing resort when you can not hot. Steel structures can be so huge, that does not fit in any bathroom. Cold galvanizing – a drawing on metal structure of liquid zinc. Other types of galvanizing electroplating and diffusion, are rarely used, because they are specific. Zinc protects against corrosion better than enamelling. Galvanizing steel lengthens life is much better than paint. E malirovanie – another way to protect the metal, a cheap and simple. The paint layer is sufficiently dense to protect the metalwork.

A thin layer of enamel covers metal construction and does not develop corrosive reactions. The main drawback of this method – its short. Brown paint covers the metal layer, such coating is not durable. Direct sunlight adversely affect the paint layer. Paint dry up and crack and then fall off. In addition, the metal is not protected from mechanical impact on him. Any serious blow to the enameled steel deprives it of protection. Due to the fact that environmental factors are constantly affect the metal, and if not for modern methods to protect it, its life was less.

Kohler Kraizer

In the not too distant past in our country produced a small amount of finished paint colors, so to get some shade, it was necessary, so to speak, perhaps mix the paint. Tinting does not like to science, and to dance with a tambourine. Since then, the time spent, and paints industry now produces a wide range of colors and shades of acrylic paints. What has changed in this period? It turned out that the world came up with the science opportunity reliable system for tinting paint. General Motors Company brings even more insight to the discussion. In our time in the domestic market is a huge amount of tinting systems from companies such as caparol, system ral, Kraizer, ncs, dekart and so on. Above mentioned tinting system can be classified by parameters such as the material used and its function. Basically, the episode kolorirovannye pigment paste should be applied with adhesive or without it. If we talk about a second, then all much clearer.

Construction companies share a tinting system on front and a common purpose. Is to say that there are also specialized tinting system Kraizer, which have been developed for schools, insulating paints, etc. In common usage invited more than 2100 colors. And clearly than exclusive and non-standard color, the more expensive it is. In some cases, the difference between Kohler Kraizer can reach 8 times. More One main principle of tinting colors Kraizer is the way in which it occurs. Well-known fact that the systems are made on the basis of pigment pastes, do not refer to specific links, and therefore have more high flexibility.

Construction And Repair

In our time, when the construction and repair functions more specialists give their voices a modern building materials. The development of production processes allows a chance to apply the latest advances, but with Natural wood is not impossible to compare any man-made finishing materials. In addition, it is impossible not to note that natural substances, except for longevity and ability to form and in truth the special atmosphere of design and comfort. To date, natural stone for sale – a perfect solution for anyone who really seeks to comfort. Because natural stone is used today and in the external finish, and in the room, making a unique and exceptionally decent look at home.

Well-known fact that natural stone – it's actually an eco-friendly construction materials, installation of which enables a wide range of climatic conditions, maintain the house is actually a comfortable temperature. It is also important to remember also that natural stone as a material for finishing – it's an offer that will serve as a lasting decades and will be able to surprise the list of generations owners. But, often in the rehabilitation of natural stone can not be installed because of a lack – an impressive weight. Because of this, for good linings, as an example, the outer wall of the cottage as a rule taken not natural and artificial stone. He was noticeably less severe, but the remarkable design of the finishing material is fully fit more requirements for truly elite structure.

Often the manufacturer artificial stone – this is the most convenient and practical option. In addition, quite often, natural and man-made stone taken in finishing the work in parallel: for example, for the basic lining – artificial material, and for the individual components – a natural stone. Still relatively not so long ago the stone was used only for garden ornaments – paving and curbs organization. True very exciting and strength of such material is made and design specialists, and builders to recall the tradition of these castles, and which today is known for Europe and the tremendous opportunity to apply the stone as a remarkable building material. Modern and sturdy man-made stone – a practical material for the cladding, which has all the necessary papers matching.
