What exactly is a concrete release agent?
A concrete release agent is a compound placed on the building design prior to the concrete is put in order that the design will not stick to to the concrete surface after putting, is just not simple to take down the cast or impacts the finish of the concrete area. Its principal role inside the template and the concrete covering to develop a movie that is going to be separated from the two is additionally called an isolation agent.
A water-based release agent is an crucial auxiliary inside the release agent and can change the water-based release agent flow and levelling; its primary feature is definitely stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based mould release agent is utilized in forms and products functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form goods are not only to be able to let the cast release to improve productivity and extend the life of the cast utilize. And can make the product clean, size qualified, and lower the generation of scrap, which can be an important additive essential to forms and goods – concrete additive.
Concrete release agent plays an important role in modern building construction; its primary role is to form a layer of separation film between the design and the concrete area so that the template will not adhere to the concrete surface to ensure that it is much easier to take down the cast after pouring and to maintain the finish of the concrete area. Here, we will introduce the types, characteristics, usage and use of concrete release agent at length.
Kinds of concrete release agent
Concrete release brokers can be divided into several kinds based on different classification strategies, and the typical grouping techniques are the subsequent:
- According to the 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 etc.
- According to the the composition of: it can be divided into water-based concrete release representatives, oil-based concrete release agents, silicone oil concrete release agents, etc.
- According to the effect of use: it can be divided into ordinary concrete release agents, easy-to-remove concrete release representatives, high-gloss concrete release representatives and so on.
Qualities of Concrete release agent
A concrete release agent is also referred to as a concrete separation agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the part of lubrication and separation so that the concrete may be easily detached from the formwork when dismantling the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete area, no corrosion of the template, simple to paint, low cost and etc. However, not all sorts of concrete release agents with a selection of supplies made of templates are suitable for different components of the template and different construction conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the following features:
Good remoteness performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete covering and facilitating the removing.
Great lubrication overall performance: concrete release agent has good lubricating efficiency, which can lower the chaffing between the formwork and concrete area, decrease the resistance during pouring and improve the construction productivity.
Good anti-adhesion overall performance: concrete release brokers can effectively stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when taking apart the formwork.
Good waterproof performance: concrete release agent has good waterproof overall performance, which can successfully stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing the service life of the formwork.
Effortless 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 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 surface.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking apart 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 covering gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking apart.
Clean up the template: after taking down 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 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 area and enhance 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 boost 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 representatives 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 construction projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the building project and provide a strong guarantee for the advancement of the construction industry.
