This damage can cost significantly large sums of the owners for repairs, replacement and maintenance, which also affects the overall productivity of the industrial unit. The repair downtime of the factory floor is even worse than the expense of repairing for most owners.
In this blog, we will learn the importance of using effective concrete admixtures for industrial floors.
What are Concrete Admixtures?
Concrete admixtures are specially formulated construction chemicals. These are used in batches and mixed with concrete before, or during the placement of the concrete. Concrete admixtures are extremely helpful in reducing the overall cost of construction.
Durability of concrete floors usually depends on proper dosage, adequate mixing and application using the infusion technique. Concrete admixtures are available in liquid or powdered form. Admixtures are normally added to the concrete on construction sites.
Industrial floors need to withstand considerable load and stress, as well as chemical attacks and mechanical abrasion frequently. Generally, the wearing surface is the top ¼ inches of the floor’s thickness. Though surface smoothness is essential, it does not ensure durability and strength of concrete floors, especially in manufacturing and processing plants.
There are numerous factors that affect the durability of concrete floors in industries. The quality of concrete used, weather conditions, climate, environment during placing, finishing procedures and substrates are the major factors that affect the overall quality of concrete floors.
However, buying quality concrete admixtures for industrial floors is probably the most crucial factor to ensure durability of floors in industrial settings.
How to Choose the Best Concrete Admixtures for Concrete Floors?
Concrete is an essential material in the construction industry and is valued for its versatility and durability. Selecting the right super plasticizing admixtures is crucial to ensure enhanced performance, longevity, and improved functionality when constructing concrete floors in industrial settings.
There are a large variety of concrete admixtures available on the market today. Most of these are ideal for use in construction of concrete floors for manufacturing, packaging and processing units. However, it is recommended to use the type of concrete admixture which fulfils the specific requirements depending on how the industrial floor will be used.
Types of Concrete Admixtures for Industrial Floors
Below are the most popular admixtures used for laying concrete industrial floors –
Water-Reducing Admixtures
Function – These admixtures lower the water content needed in the concrete mix yet maintain its workability.
Advantages – Water-reducing admixtures offer improved workability, enhanced strength and durability, reduced permeability, and better surface finish.
Application – This type of admixture is usually added during the mixing process. Water-reducing admixtures can be used in varying dosages to achieve desired results, for example high early strength or extended workability for complex placements.
Superplasticizers>
Function – Superplasticizers (high-range water reducers) greatly improve the fluidity of concrete without the need to increase the water content.
Advantages – Superplasticizers offer high fluidity and workability and lowered risk of segregation and bleeding. These concrete admixtures also produce high-strength concrete with a low water-cement ratio.
Application – Superplasticizer concrete admixtures are ideal for concrete floors that require stronger surface finishes and complex formwork. These are mixed with concrete just before or during the pouring phase.
Air-Entraining Admixtures
Function – Air-entraining concrete admixtures produce microscopic air bubbles into the concrete mix.
Advantages – This admixture enhances freeze-thaw resistance, improves workability, minimizes risk of scaling, and offers better durability to concrete floors in harsh weather conditions.
Application – Air-entraining admixtures are commonly used in exterior concrete which is frequently exposed to freezing conditions. These admixtures are added during mixing to ensure even distribution of air bubbles in the concrete.
Accelerating Admixtures
Function – Accelerators speed up the hydration process of cement which helps in faster setting and early strength gain.
Advantages – Accelerating admixtures reduce curing time, ensure early strength development, are beneficial for concreting in cold climate, and have quicker turnaround time for flooring.
Application – Accelerator admixtures are useful in environments where quick repair and rapid serviceability are critical. These accelerators are mixed with concrete either in the plant or at the construction site.
Retarding Admixtures
Function – Retarding admixtures slows down the setting time of concrete.
Advantages – These admixtures extend the concrete’s workability, prevent cold joints in large pours, and provide enhanced finish quality.
Application – Retarding admixtures are ideal for use in hot weather concreting or complex structural elements that require extended work time. These are typically added during the initial mixing process.
Corrosion-Inhibiting Admixtures
Function – Corrosion-inhibiting admixtures protect embedded steel reinforcement from corrosion.
Advantages – These admixtures help to extend the lifespan of concrete structures, reduce maintenance costs, and improve durability of concrete floors in high-traffic and load-bearing environments.
Application – Corrosion-resistant admixtures are especially useful in industrial floors exposed to chemicals and moisture. These construction chemicals are mixed into the concrete during the batching stage of construction.
Shrinkage-Reducing Admixtures
Function – Shrinkage-reducing admixtures restrict the amount of shrinkage that occurs as concrete dries and hardens to the lowest.
Advantages – These admixtures reduce cracking and curling, improve structural integrity, and enhance aesthetic quality.
Application – Shrinkage-reducing construction chemicals are designed for use on large concrete floors and slabs. These admixtures are integrated into the mix during the batching stage to ensure balanced distribution.
Application Methods and Benefits of Concrete Admixtures
Applying concrete admixtures correctly is crucial for achieving the desired properties in the finished floor.
Generally, concrete admixtures for industrial floors are added during the mixing process to ensure uniform distribution throughout the concrete. This can be done at the batching plant or on-site. The choice of mixing admixture to concrete depends on the specific requirements of the project.
Construction experts recommend carefully pouring the concrete to form a smooth and consistent layer, measuring at least 8-10 inches thick. This is ideal to create strong and durable floors for industrial settings. Besides, it is necessary to choose the right admixture to mix with concrete if you want to ensure the concrete floor has superior compressive strength and ability to withstand significant wear and tear for a long duration.
