Types and features of cement

Cement is one of the most frequently purchased building materials in London. No construction can do without it. Clinker, minerals and gypsum crushed to a powdery state are used for its production. Buy cement 500. This composition gives cement the ability to easily mix with water and then quickly harden in the open air. Portland cement is usually used for construction. It is made from bricks that combine clay and limestone in a certain proportional ratio. Their firing takes place in a specialized furnace. As a result, it is possible to obtain a reliable material with high strength and excellent characteristics. To buy cement in big bags. Cement in London is realized of various types, each of which has its own advantages and application features. They are represented by:

• Sulphate-resistant Portland cement. In clinker for its manufacture, the level of calcium aluminates is reduced. Such material may include active mineral additives, it can withstand the effects of sulfates and cold well. Therefore, it is used to create reinforced concrete structures for various purposes.
• Fast-hardening Portland cement. Due to the addition of minerals to the composition, its first hardening period is quite intense. A special proportional ratio of the components allows for increased mechanical strength. Such material is indispensable in high-speed construction.
• Cement with hydrophobic components. This material has a low water absorption. The resulting structures are resistant to moisture.
• Cement with surfactants. Each grain of such a material is covered with particles of plasticized material that form a protective film. Due to this, cement acquires high mobility and is optimally suited for creating architectural structures of increased complexity.
• Grouting Portland cement. It is used to isolate oil and gas wells from the effects of groundwater. At various temperatures and pressures, it is able to provide a reliable fixation. It has a high level of strength.
• White and colored Portland cement. With their help, concrete structures of different colors are created in London. A certain shade is achieved by adding a coloring segment.
• Pozzolan Portland cement. Resistant to sulfates and fresh water. When solidified under the influence of high temperatures, it gives the concrete products increased strength. It is not able to solidify at low temperatures. Products made of such cement are used for structures located underwater or underground.
• Slag cement. There are two types. Granulated blast furnace slag, standard clinker and gypsum are used for the manufacture of slag-prothland cement. Such a material is slowly gaining its strength. But in the future, he is not afraid of the aggressive effects of moisture and other adverse environments. The second type is represented by limestone-slag cement. It includes lime, blast furnace slag, gypsum and Portland cement. This composition hardens slowly, but tolerates the effects of fresh and sulphate waters well. Buy cement PC. It is allowed to use in low grade concrete, as well as in solutions for masonry and plastering.
• Alumina cement. It consists of alumina and calcium aluminate, which promotes rapid solidification. The finer the grinding of the material, the faster it seizes. An increased amount of water is required to make the solution. Due to the high liquid consumption, shrinkage is minimized and resistance to cold increases. This material is well suited for high-speed construction and urgent repair work.
• Expanding cements. The solutions created from them increase in volume due to the combination of special additives and a binder component. The material is represented by waterproof, gypsum-alumina, straining and Portland cement varieties, each of which has its own application features.
