Types of concrete
« : 01.48.2023 14:48:06 pm »

ordinary concrete
It is obtained by mixing the basic components of cement, water and aggregate to obtain concrete of normal strength. The strength of this type ranges between 10-40 MPa, and the initial setting time ranges from 30-90 minutes. This, in turn, depends on the properties of the cement and the weather conditions at the construction site.

type concrete
Reinforcing elements are inserted into this type of concrete to make it bear tensile strength; One of the characteristics of ordinary concrete is that it is weak in tensile strength and good in compression, and the reinforcing steel used in concrete can be in the form of rods, networks, or fibers that have recently been introduced to this area, and it is very necessary to ensure proper bonding between the concrete and the supports, whatever the type of support. used in it, and it is this interconnection that controls the factors of strength and durability of concrete.

Lightweight concrete
Concrete weighing less than 1,920 kg/m3 is classified as lightweight concrete. The different types of aggregates used in the manufacture of lightweight concrete are classified into: natural materials such as pumice, scoria, industrial materials, and curing materials, and their most important properties are very low thermal conductivity, and they are used to protect steel structures, for thermal insulation and as building blocks.

High density concrete
The density of this type ranges between 3000-4000 kg / m3, and it is prepared using high-density crushed rock, such as coarse aggregate, and this type is often used in atomic power stations and other similar buildings, because it provides good protection from all types of radiation

Architectural and decorative concrete
This type can provide structural function, aesthetic or decorative finishes, smooth or rough surfaces, and a wide variety of colors.

Rolled concrete
This type is pressed and processed in the workplace, with a drop value of zero, and it is characterized by its corrosion resistance, which makes it suitable to withstand high water velocities, and it is usually used in water channels and other infrastructures that are exposed to conditions of high water flow, and it is considered an ideal and competitive solution from In terms of cost and durability when compared to asphalt
