Lime and its products in the construction industry

It is hard to imagine the construction process without the use of special materials. Literally each construction stage requires its own range of materials, the choice of which is due to the requirements for this phase of work. Despite this fact, there are building materials that are used throughout the process of construction of the building, almost regardless of its purpose. Such materials include building dry mixes, which become the basis for the preparation of cement and other materials.

The composition of building mixes may vary depending on their use. The most mixes include construction lime, which properties guarantee high adhesion and durability of the final result. Construction lime is indispensable in the stone work, because it can help to achieve a high rate of bonding surfaces. Floor tiles for the bathroom are often built using a mixture which includes lime. It should be noted that this material is environmentally friendly and does not cause allergic reactions, which allows its use in the construction and finishing work carried out in residential areas.

During work on the decoration of the bathroom you should not only consider the quality of supplies, but also take into account the size of the future plumbers, for example, bath. This will not just calculate the amount of materials needed, but also to conduct all work quickly, the quality, without the need to eliminate the deficiencies.

The choice of plumbers today is so diverse that every customer can select the elements of plumbing not only according to their perceptions of the quality of products, not only in terms of financial capacity, but also picking up on the stylistic elements. Some people prefer the classics, others prefer vanguard and so on.

If the first phase of construction work is carried out laying the foundation and used cement mixture, one of the latest treatments is plastering and hydraulic lime surfaces. When it comes to foundation, hydraulic lime is used – the fine powder obtained by calcining marly limestones containing 6-20% clay and fine sand impurities at 900-1100°C. Thus, silicates, alumina and ferrates are formed, giving this ability to maintain long-term durability in the water after the pre-hardening in the air. This solution is widely applied by time-tested, innovative architectural agencies, such as a UK-based Telling Company – the specialists resort to hydraulic lime and lime mortar materials on a regular basis.

Production of hydraulic lime

The production consists of firing of raw materials, quenching calcine, unslaked particle separation and grinding and mixing the crushed grains with slaked material. In some cases, a mixture of ground and slaked part of the material is not produced, and therefore, 2 separate product are manufactured.

Hydraulic lime calcination temperature depends on the composition and structure of the roasted material. The more clay magnesia and impurities it contains, the lower the firing temperature must be (although hydraulic lime is burned within the 900-1100 ° C range as a rule).

The process of hardening of hydraulic lime contains elements of air and hydraulic curing. The first one takes place due to the presence of calcium hydroxide, which is the evaporation of excess moisture is gradually crystallised and carbonised in the surface layers under the action of carbon dioxide.
