A foundation in a house or other building is a basic structural element, having a decisive impact on the durability of the facility, but also on the safety of its use. A very important issue is also the fact that mistakes made in the selection of materials and the construction of this element are virtually irreparable, and if possible, repairs are usually very expensive. The basic structural material during the construction of foundations is concrete and reinforcing steel. Here’s what to look for when choosing concrete for the foundation.
The right concrete is very important
The basic parameter of concrete for foundations is compressive strength. This strength is selected on the basis of anticipated future loads and is always specified in the construction design. The strength of the concrete is marked with the appropriate letter and number symbol.
The markings describe the compressive strength class, which means that concrete for a foundation in a given project should have a minimum strength of 20 MPa. The difference in the markings results from the existing standards for concrete. The strength class C16 / 20 is the most commonly used variant in single-family house designs, but as mentioned above, each time should be specified in the construction project.
The consistency class is a parameter for a concrete mix. When choosing concrete for the foundation and construction of a single-family home, a mixture in the consistency class S3 or S4 is usually used. A higher number next to the symbol S means a higher fluidity of the mixture, which in turn affects the possibility of properly compacting the concrete mix in the formwork.
How to build an environmentally friendly infrastructure?
When deciding on the choice of concrete, it is also worth ensuring that it is ecological. Along with the progressing environmental pollution and legal sanctions limiting the amount of carbon dioxide emitted into the atmosphere, scientists are looking for ways to reduce or store CO2, so that the production of concrete is burdened with less emission of this gas. Glass reinforced concrete cladding is very popular in recent times. It has not only an excellent structure and is environmentally friendly, but also has a very high strength.
