What exactly is a concrete release agent?
A concrete release agent is a substance applied to the development design just before the concrete is added so that the template doesn’t adhere to the concrete covering right after putting, isn’t simple to take apart the cast or influences the complete of the concrete area. Its main role inside the template and the concrete covering to form a film that is going to be separated from the two can also be referred to as an isolation agent.
A water-based release agent is definitely an essential auxiliary within the release agent and can change the water-based release agent flow and levelling; its principal attribute is stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based cast release agent is used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing cast items are not only in order to let the cast release to enhance productivity and lengthen the life of the form make use of. And can make the product clean, size qualified, and decrease the generation of scrap, that is an crucial additional essential to forms and items – concrete additive.
Concrete release agent plays an crucial role inside modern building development; its main role is to form a layer of isolation film between the design and the concrete surface to ensure that the template doesn’t adhere to the concrete surface so that it is simpler to take apart the mould following putting and to maintain the end of the concrete surface. Here, we will introduce the sorts, qualities, usage and application of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release representatives can be divided into many sorts based on different grouping techniques, and the typical classification methods are as follows:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
- According to the formula of: it can be divided into water-based concrete release brokers, oil-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the effect of use: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release brokers, high-gloss concrete release agents and and so forth.
Characteristics of Concrete release agent
A concrete release agent is also known as a concrete isolation agent or mould release lubricant. It is actually a type of material coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete can be smoothly detached from the formwork when taking down the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and so on. However, not all types of concrete release agents with a selection of supplies made of templates are suitable for different supplies of the template and different construction circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the next characteristics:
Good isolation overall performance: concrete release agent can form a dense isolation motion picture between the formwork and the concrete covering, effectively avoiding the formwork from bonding with the concrete surface and facilitating the removing.
Good lubrication efficiency: concrete release agent has good lubricating efficiency, which can lower the rubbing between the formwork and concrete surface, lower the resistance during pouring and enhance the construction productivity.
Great anti-adhesion efficiency: concrete release agents can efficiently prevent the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete surface when taking apart the formwork.
Great waterproof overall performance: concrete release agent has good waterproof performance, which can efficiently prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving the service life of the formwork.
Effortless to use and safe: concrete release agent is easy to use; you only need to apply a layer evenly on the formwork; at the same time, it is safe and environmentally friendly and will not pollute the human body and the environment.
When using a concrete release agent, the following steps should be followed:
Prepare tools: concrete release agent is usually sprayed or brushed for construction. You need to prepare construction tools such as a sprayer or brush.
Choose the right release agent: According to the different environments, choose the right concrete release agent, such as indoor use can choose a water-based concrete release agent, and outdoor use can choose an petroleum-based concrete release agent.
Apply the release agent: Pour the appropriate amount of release agent into the sprayer or container, and then evenly spray or brush on the formwork to ensure that each part is coated in place.
Air drying: After application, wait for a period of time to allow the release agent to dry naturally. Generally, it takes 10-20 minutes, depending on the environment.
Pouring concrete: After the release agent is completely air-dried, the concrete can be poured. During the pouring process, care should be taken to avoid air bubbles or voids between the formwork and the concrete area.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When dismantling the formwork, the connectors at the edge of the formwork should be dismantled first, and then the covering of the formwork should be knocked gently to separate the formwork from the concrete area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking down.
Clean up the template: after dismantling the template, the template should be cleaned up to remove the residual concrete and mould release agent. After cleaning, it can be used for the next time.
Application areas of concrete release agent:
Concrete release agent is widely used in all kinds of construction projects, mainly including the following aspects:
Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding formwork from bonding with concrete and improving construction efficiency and quality.
Road construction: in road construction, the concrete release agent can be used to isolate the bond layer between the road formwork and concrete covering, to avoid road bubbles, hollow drums and other problems.
Bridge project: In a bridge project, a concrete release agent can be used to isolate the bond layer between the bridge formwork and the concrete surface and improve the construction quality of the bridge pier and abutment.
Tunnelling project: In the tunnelling project, a concrete release agent can be used to isolate the bond layer between tunnel formwork and shotcrete surface to improve the quality and safety of tunnel construction.
Nuclear power project: In nuclear power project, a concrete release agent can be used to isolate the bond layer between the shell of nuclear power equipment and internal components to ensure the safety and stability of the equipment.
Other fields: concrete release brokers can also be widely used in water conservancy projects, wharf projects, airport projects and other fields to provide effective formwork isolation protection measures for various construction projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the construction industry.
