The main types of concrete used in construction include smooth concrete, high density concrete, lightweight concrete, precast concrete, reinforced concrete, prestressed concrete, shotcrete, airborne concrete, self-consolidated concrete, and glass reinforced concrete. This form of concrete is widely used in industry and modern construction. The strength of reinforced concrete is favored by the placement of wires, steel rods or cables in the concrete before they set. A more familiar name for these items is reinforcing bar which ideal with welding application.
Lately, people have used fibers to reinforce this concrete. Invented in the 19th century, it drastically changed the construction industry. Buildings, Bridges and Roads Rely on Reinforced Concrete. When moving near a construction site, you are likely to see concrete reinforced with rebar.
Many large concrete projects use prestressed concrete units. Prestressed concrete is created using a special technique. Like reinforced concrete, it includes bars or tendons. But these rods or tendons are tensioned before the actual application of the concrete. You can consult with Concreting Canberra for more detailed information about your particular concreting application.
This process makes the lower section of the unit stronger against tensile forces. However, it requires heavy equipment and skilled labor. Typically, pre-tensioned units are created and assembled on site. Prestressed concrete is used to build bridges, heavy-duty structures, or roofs that have long spans.
This concrete is created and cast in a factory according to exact specifications. Precast concrete units are transported to the site and assembled. The advantage of using precast concrete is its quick assembly. Since the units are manufactured in a factory, they are of very high quality.
Air is entrained in the concrete by the addition of various foaming agents, such as alcohols, resins, or fatty acids during the mixing process. This must be done under careful engineering supervision, since the concrete is mixed on the job site. The entrained air accounts for between 3% and 6% of the concrete volume. Almost all concrete used in a freezing environment or where there are freeze-thaw cycles is entrained by air.
This is the concrete technology of the future. Offers a different way to monitor the condition of reinforced concrete structures. The short carbon fibers are added to the concrete using a conventional concrete mixer. This affects the electrical resistance of concrete when it encounters deformation or stress.
This type of concrete can be used to detect potential problems before concrete fails.

There are 25 different types of concrete that are discussed below.
Some other types of concrete are sulfur-impregnated concrete, roller compacted concrete. Ready-mix concrete is the type of concrete that is manufactured in a factory and then delivered to construction sites via trucks composed of in-transit mixers. It is manufactured under controlled operations and transported and placed on sites using highly sophisticated vehicles and methods. This means that special concrete mixes already produced will only need to be poured onto the construction site.
While ready-mix concrete began production in the 1930s, it wasn't until the 1960s that its market began to expand. The reason ready-mix concrete is preferred over onsite concrete mixing is that it helps reduce confusion in the workplace and offers high-precision mixing. Volumetric concrete is used as an alternative to ready-mix concrete to overcome the problem of curing concrete over the long distances between factory and construction sites. After mixing, it is important to maintain proper humidity and temperature conditions to keep it in usable form.
Volumetric concrete uses specialized trucks known as volumetric mobile mixers that transport concrete ingredients and water to be mixed on the construction site. This helps eliminate any travel delays that could cause ready-mix concrete to become unusable. The fully mobile volumetric mixer serves here as a dosing plant. This also allows you to pay for what you use, as well as adjust the mix design to suit your construction needs and site conditions.
Volumetric concrete is especially useful when two separate mixes are required for different projects at one site, so that the concrete can be mixed on demand. Some common applications include large sites, multiple projects, basement constructions, etc. Decorative concrete is the type of concrete that has been treated in a variety of ways to increase its aesthetic appeal. For example, it can go through processes such as coloring, texturing, molding, polishing, engraving, engraving, embedding items, applying decorative coatings, etc.
Various materials are used in the production of decorative concrete, such as the color hardener that offers a unique color as well as a highly durable surface; integral color can be used in any texture and application. Finally, the chemical dye gives a natural stone look by producing an uneven, translucent color. Therefore, decorative concrete is ideal for projects that seek to create an aesthetic impact. It is also used to add elements of dynamism to uninteresting surfaces and materials.
Some common applications include decorative floors, swimming pools, pavements and architectural implements. Fast-setting concrete is the perfect mix when it takes little time to complete construction projects. Offers faster set times and is highly resistant to low temperatures. This means that it is an ideal type of concrete for use in winters, when the cold does not allow the use of ordinary concrete.
This type of concrete is compacted by heavy rollers to make it strong and dense enough to support heavy loads and vehicles. While deployed similar to asphalt, roller-compacted concrete uses less energy for production and requires less finishing and formwork. In addition, the production of roller compacted concrete produces lower emissions, which benefits the environment. Roller compacted concrete is used for roadworks, pavements, airport taxiways, car parks and industrial surfaces.
Whether you are looking to execute a large-scale project or are interested in building a domestic building, the concrete mix you choose will have a big impact on the success of the project. Stamping can be done with concrete seals made of polyurethane. Embossing gives a relief and elegant look to concrete, which is often considered decorative. Ready-mix concrete is preferred when there is less space for storing and mixing construction materials.
Concrete fiber is a composite material consisting of a mixture of cement, concrete or mortar and suitable discrete, discontinuous and uniformly dispersed fibers. Self-compacting concrete is a special type of concrete composed of cement, fine aggregates, coarse-grained aggregates, chemical additives to improve workability, fluidity, rheology and mineral additives. Prestressed concrete is a special type of concrete that goes through the prestressing process to achieve the required shape. Retarders are typically added to the concrete mix to slow down the setting process and allow for transportation and time placement of concrete.
For a residential project, don't hesitate to ask your concrete contractor if precast concrete elements would be right for your project. Epoxy is the largest category due to its increasing use in construction and its superior properties of high impact resistance, high vibration resistance, good bonding with concrete and metal surfaces. Volumetric concrete is extremely useful when a builder requires two different types of concrete mix on a single site. Permeable concrete is a special type of concrete that has a high porosity and allows water to pass through it and recharge groundwater.
While mixtures most commonly used in the production of polymer concrete include vinyl ester, polyester, and normal epoxy, other types of polymer resins that can help pour and harden concrete can also be used. Ready-mix concrete is factory-made concrete made of cement, aggregates, water and additives and is transported to the site. This is a form of smooth concrete that contains microscopic air bubbles ranging in size from a few thousandths of an inch in diameter to a few hundredths, and typically make up between 4 and 7% of the total volume of concrete. .
