The type of concrete work you need for your construction depends on the project at hand. The demands that come along with the type of concrete used in a commercial project are different from the ones in residential projects. They may differ in terms of stability and vigor. For example, the type of concrete that is used in restaurants is not the same as the one in a warehouse.
This article contains a variety of concrete works that are suitable for commercial concrete work.
1. Normal Concrete in Concrete Construction
Also known as Normal Weight or Normal Strength concrete this is the most famous type of concrete works in the industry. It possesses fair strength that makes it suitable in constructing walls, buildings, and skyscrapers. In the preparation process, regular cement is mixed with water and aggregates. Examples of aggregates used in the process are sand and stones.
Later the mixture is allowed to settle for at least more than one and a half hours. The duration depends on the mixing and elements found in the cement used. One thing that makes this concrete very common in both formwork and concrete construction is its innumerable applications. However, the only flaw it has is that it’s very difficult to decorate. It is also not suitable in an area where the weather is severe.
2. High-strength Concrete for Concrete Construction
Second, on the list is the high-strength concrete. This type of concrete is perfect in commercial areas where heavier loads are expected. Unlike in the preparation process in Normal Concrete, here the ratio of water to cement is lower. The aggregate used is of a higher quality and also some admixtures are added to make the concrete mixture even stronger.

For the mixture to come out perfectly to has to settle for a longer time than the Normal Concrete. This type of concrete work is majorly applied in formwork or concrete constructions like bridges, foundations, and shears. It is advantageous in terms of durability and stability. The only shortcoming that it has is that it requires mastery to achieve a perfect concrete mix.
3. The High-Performance Concrete in Concrete Construction
High-performance concrete has many characteristics like the ones found in high-strength concrete. This type of concrete work is highly applicable in the formwork construction of large pillars, warehouses, and facades.
The difference in this type of concrete, when compared to the high-strengthened one, is that in terms of sturdiness, this one is way stronger. In terms of durability, high-performance concrete lasts longer than high-strengthened concrete. Just the same way high-strength concrete needs a professional in the mixing process so does the high-performance.
The list cannot be complete with the mention of the newest type of concrete work in formwork and concrete construction. Air-entrained Concrete is the most recent; however, it is applicable for special uses. This is because unlike the other concrete works above, this one is less durable and less sturdy. This is because of the admixtures element that is included in the mixture that makes traps the air inside the concrete. You need to know the type of concrete work that suits your project. This will be very beneficial in crucial things like the safety of the people around and the maintenance cost.
It gives a sense of relief and comfort to know that your house is constructed on a solid base. Analyzing the base of the building that you are working on is crucial. The analysis must be done before the concrete is poured. Analyzing it after the concrete is poured makes it difficult for one to tell or see any deformities or issues within the formwork or the concrete structure. Failure to do this may result in unnoticed defects finding their way into the structure. At this point, the damage will already be done and it will be too late or very expensive to undo it.
This article is for any surveyor’s inspector that needs tips to guide him or she analyzes the efficacy of a suspended concrete slab. Below are the secrets that you need;
Step One: Check for the Support at Maximum Moment
This is normally done according to the engineer’s plan. While at it, always check the shape of the bending moment. Remember to do more than just checking for adherence from the blueprint or the drawing.
It is important as an analyst to know where more support is needed. Find out if the maximum support of the suspended slab positioned corresponds to the highest tilting moment. Always aim for something better than the minimum standard.
Step Two: Identify Where the Supports are Located
Make sure that the supports are exactly where the layout engineer thinks they are. They should be correspondent to the blueprint or the drawings. There are a lot of concrete constructions where its builders used limited supports than how the engineer had earlier anticipated. To identify where the supports are located you should;
- Check if the support that from the columns are in line with the blueprint
- See whether the load-bearing walls are constructed on the suspended slab’s underside
- Check whether the suspended concrete slabs are joined to the wall or not
Step Three: Confirm Whether the Concrete Strength Used is the Correct One
This step is very crucial because not all concrete constructions and formwork use the same concrete strength. The drawing or the blueprint should clearly state what kind of concrete strength is to be used on the project. On also inquire from the builder on the type of concrete strength to be used. Concrete strength depending on the structure has a lot of importance. For example, high-performance concrete has enough strength to withstand a lot of weight.

This means that the concrete’s strength will determine the durability, serviceability, and porosity of the surface.
Step Four: See Which Supporting Layers are positioned first and last
Ensure that the builder has positioned the steel correctly. Steel support that is closer to the tension face is usually the most effective one. If a mistake is found, then more steel can be placed before the concreting process. Use the drawing or blueprint and make sure that the steel is placed correctly
Step Five: Suspended Concrete Cover in Concrete Construction
Before the concrete is poured always make sure that the correct cover is usually used. Check whether the suspended slab support is properly positioned in the slab. In a situation where the whole thing is too close on the surface, the steel might end up corroding and disappoint.
In situations where tapes are used, you can always pull them off to confirm the upper and bottom cover.
Concrete tilt-up are types of concrete constructions that occur by lifting and tilting of concrete panels by the use of cranes to form a building wall.
The panels can be molded in different shapes including flat or even some in curved sections.
They are easy and fast to assemble because the concrete formwork placement is performed on the floor. Checkout more about concrete formwork on https://www.icfmag.com/
How Concrete Tilt-up Panels Works in Concrete Construction
Tilt-up construction focuses on many sequences of concrete panels tilted upwards and stands as the final exterior wall.
You will need a wood form, rebar, and concrete to create the panels according to the desired designs. These wood forms are shaped and rebar cut according to every final design.
Concrete work is then poured into the form created. When the panels are dried up and ready, they are tilted and set as the exterior wall.
Once the external structure is ready, it is bound together by roofing to make a complete building.
Uses of Tilt-up in Concrete Construction Works
Tilt-up construction was used in the construction of warehouses and storage places during post world war II times.
With the advancement of technology, the invention of truck mixers and controlled cranes has influenced the spread of tilt-up construction as one of the techniques used today.
Today this technique is used in building schools, hospitals, houses, and almost most buildings because it is safe and very inexpensive.
The most common uses for concrete tilt-up construction is in the large scale of distribution centers and warehouses.
Advantages of Concrete Tilt-up Systems in Concrete Construction
Tilt-up construction is said to be advantageous as compared to traditional building ideas. Some of the advantages are as follows
Concrete Construction Tilt-up Systems is quick
Once the concrete work is done and placed, the panels will take fewer days to cure. When it comes to tilting, the controlled cranes do it faster which saves time.
Assembling the concrete construction walls is also faster as compared to building the walls using other traditional techniques.
Concrete Construction in Tilt-up Panel is Cost friendly
The cost-friendly aspect is effective in both labor and material to be used. You can have a handful of workers to do the concrete placement then crane operators lift the panels into place. These lead to reduced labor costs with fewer workers to pay.
Construction material can be obtained easily from suppliers in your area. Ready-mix concrete and rehab are some of the readily available materials.
Concrete Construction Tilt-up Creates Flexibility in Design
Technology has changed the construction industry by the introduction of software systems.
These systems can design a structure to the exact specification and reduce unnecessary costs from the construction budget.
When it comes to exterior cladding, the software database has a variety of materials to choose from.
The panel walls can be positioned at any angle, provided they can fit better in the design of the concrete construction structure.
Concrete Construction Tilt-up Panels Saves Energy
Reinforced concrete is an insulator. This means it strengthens thermal properties and builds up another insulating layer for energy saving.
The concrete tilt-up panel system is durable. The wall is strong compared to wood or cement blocks. However, they are not recommended in areas prone to quake.
The concrete construction is fire resistant which provides the concrete wall with a good fire rating.
Before tilting you can inspect for cracks or any defaults, this will help you know if the panel is either strong, weak, or needs repair.
Always work with experts when using the Concrete tilt-up system for good strong and reliable concrete construction structures.
High rise construction is becoming popular in the world today with high demand for offices, rentals, business premises and also due to lack of land.
Formwork and concrete construction has enabled these multi-story buildings to be a reality.
Different materials are used in formwork in the construction of a story building. Some of the materials are as follows
Aluminum Concrete Formwork in Multi-storey Building
Aluminum formwork is flexible in handling all types of design when it comes to concrete construction.
Multi-story buildings need a lot of labor force since there’s a lot of work involved. With this in mind, you can have unskilled workers since they can handle aluminum formwork components. The use of steel pins and steel formwork ties is involved in holding and securing the aluminum wedges.
Aluminum concrete formwork components are very light. These are suitable for all workers because they can carry the components from floor to floor for easy assembling and recycling.
Aluminum Concrete Formwork Ensures Stability and Saves Time.
Aluminum concrete formwork saves time. This means it takes a shorter time to finish a one-story building which also reduces the budget cost of administration.
Multi-story buildings need good stability. Aluminum concrete constructions ensure there is a good bearing of the assembled alloy plates.
Aluminum Formwork in Concrete Construction Provides Safety Efficiency
High rise building has a large working area with a lot of activities going on. Within the large surface area, there should be measures put in place for the safety of all workers.
The framework formed gives strength to the tall building which then offers security to the surrounding environment.
Plastic Concrete Formwork in Multi-storey Development
In the multi-story concrete construction, security is a key level because of the nature of the work involved. Plastic concrete formwork provides the exact nature of the intended solid structure as per design. These give the story a smooth surface and quality of the design.
Plastic Concrete Formwork is Cost friendly
Multi-story construction can be very costly before construction. Consider some of the concrete formwork that will be cost-friendly and plastic concrete formwork can be a good idea. Plastic concrete formwork is very light and easily moveable. These make it reusable several times, especially on the many story floors.
With the complex shapes and sizes that the multi-story construction has, plastic concrete formwork can be easily cut to suit the shapes. Aluminum formwork systems are the most used type of material in building high rise structures like apartments and commercial buildings.
It exists as one of the unique systems used widely which makes it convenient and effective. If you want perfection in the layout of your concrete construction then this is the best way to achieve it.
The use of aluminum eliminates the need for plaster and masonry because the forms are smooth and the walls are concrete.
Aluminum used in multi-story concrete construction does not require support either from the timber or plywood activities.
Aluminum has one major problem, a mismatch of holes in the materials used. With proper inspection, this kind of problem can be resolved.
