Cement and lime

Cement and lime                              

Cement and lime are the basic construction materials necessary for almost every investment. Cement, a suitably sintered and ground mix of crushed mineral material and gypsum, is the most popular mineral binder in the construction industry. It is the main component of concrete, the properties of which are fundamental for the durability of the entire erected structure. It is a very important role, hence, every kind of cement made available on the market must conform to rigorous standards as governed by European norms. There are five basic types of cement:

- CEM I – Portland cement – composed of 95% of Portland clinker, it is resistant to low temperatures and fast-binding, and requires being doused with water when drying. This is cement that will prove itself e. g. when erecting reinforced structures.

- CEM II – Portland cement containing additives that exceed 5% of the entire content. It is used for the production of diverse masonry and plaster material, as well as base and stabilising layers.

- CEM III – slag cement, a mix of Portland clinker and granulated furnace slag. It is very resistant to the influence of sulphates in the environment (that is why it is used e. g. when casting foundations). However, it is characterised by a very long drying time (up to over a dozen days) and the necessity to douse it with water frequently in order to avoid cracks.

- CEM IV – pozzolana cement, a product characterised by increased resistance to environmental factors; used similarly to slag cement and proves itself under very difficult environmental conditions.

- CEM V – multi-ingredient cement that might be characterised by various ingredients and be used very widely in the construction industry. Multi-ingredient cement types are the basis not only of mortars and concrete, but various mixes and precast construction components.

Hydrated lime is a necessary component of masonry and plaster mortar. It is a completely natural construction material that is made by sintering active burnt lime. Cement and lime mortar is characterised by very good adhesion capacity to base materials thanks to the influence of the lime. Its particles are very small, thanks to this they can enter the pores and rough surfaces, providing them at the same time with suitable permeability. A particular advantage of lime is high resistance to the influence of fungus, mould or insects. That is why mortar with added lime is particularly recommended for residential areas or places more susceptible to the influence of humidity.
