What exactly is a concrete release agent?
A concrete release agent is a compound applied to the building template just before the concrete is put so that the template will not adhere to the concrete area following putting, is not effortless to dismantle the form or impacts the end of the concrete surface. Its main role inside the design and the concrete surface to develop a motion picture that will probably be separated from the two is additionally called an separation agent.
A water-based release agent is an crucial supplementary in the release agent and can alter the water-based release agent stream and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based mould release agent can be used in casts and goods functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form goods are not just in order to let the mould release to improve productivity and lengthen the life of the form use. And can make the merchandise thoroughly clean, size qualified, and reduce the generation of scrap, which is an essential supplementary essential to forms and items – concrete additive.
Concrete release agent plays an essential role within modern building construction; its main role would be to form a layer of isolation motion picture between the design and the concrete area so that the template will not stick to the concrete area in order that it is easier to take apart the form after pouring and to maintain the complete of the concrete covering. Here, we will introduce the sorts, features, usage and application of concrete release agent at length.
Kinds of concrete release agent
Concrete release agents can be divided into several types based on different grouping methods, and the common classification strategies 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 release agent for tunnels and so on.
- According to the formula of: it can be divided into water-based concrete release brokers, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release representatives, high-gloss concrete release representatives and etc.
Characteristics of Concrete release agent
A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is really a kind of substance coated on the inner wall of the formwork to play the part of lubrication and isolation so that the concrete may be effortlessly detached from the formwork when taking down the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and and so forth. However, not all sorts of concrete release brokers with a variety of supplies made of templates are suitable for different supplies of the template and different construction problems and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the subsequent features:
Good remoteness performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete surface and facilitating the demolding.
Good lubrication performance: concrete release agent has good lubricating efficiency, which can decrease the chaffing between the formwork and concrete covering, decrease the resistance during pouring and improve the construction productivity.
Excellent anti-adhesion performance: concrete release agents can successfully avoid the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete surface when taking down the formwork.
Excellent waterproof performance: concrete release agent has good waterproof efficiency, which can effectively avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing the service life of the formwork.
Easy to use and safe: concrete release agent is simple 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 oil-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 surface.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking down 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 dismantling.
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 agents can be used for formwork isolation, stopping formwork from bonding with concrete and increasing 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 surface, 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 covering 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 agents 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 crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right kind, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the construction industry.
