What is actually a concrete release agent?
A concrete release agent is definitely a compound placed on the building design before the concrete is put in order that the template does not adhere to the concrete surface right after pouring, is just not simple to take apart the mould or affects the finish of the concrete covering. Its primary role in the design and the concrete covering to form a movie that is going to be separated from the two is also called an separation agent.
A water-based release agent is definitely an important supplementary within the release agent and can alter the water-based release agent circulation and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is used in moulds and items functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing mould products are not only to be able to let the form release to enhance productivity and prolong the life of the mould make use of. And can make the merchandise thoroughly clean, size qualified, and reduce the creation of scrap, which can be an crucial supplementary important to moulds and items – concrete additive.
Concrete release agent plays an crucial role inside modern building construction; its primary role is always to create a layer of isolation movie between the template and the concrete surface so that the design doesn’t adhere to the concrete area to ensure that it is much easier to take apart the mould right after pouring and to maintain the finish of the concrete area. Here, we will introduce the sorts, features, usage and use of concrete release agent in more detail.
Types of concrete release agent
Concrete release representatives can be divided into many kinds based on different grouping strategies, and the common classification strategies are the following:
- According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
- According to the the composition: it can be divided into water-based concrete release brokers, 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 agents and and so forth.
Features of Concrete release agent
A concrete release agent is also known as a concrete separation agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the role of lubricating and isolation to ensure that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low cost and and so forth. However, not all kinds of concrete release agents with a selection of components made of templates are suitable for different materials of the template and different development circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the next characteristics:
Good isolation overall performance: concrete release agent can form a dense isolation film between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete covering and facilitating the dismantling.
Excellent lubrication performance: concrete release agent has good lubrication efficiency, which can lower the chaffing between the formwork and concrete area, decrease the resistance during pouring and improve the construction effectiveness.
Good anti-adhesion efficiency: concrete release representatives can effectively stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when dismantling the formwork.
Good waterproof performance: concrete release agent has good waterproof efficiency, which can effectively avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.
Simple 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 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 area 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 area, tools can be used appropriately to assist in the dismantling.
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 building projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives 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 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 surface 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 enhance 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 boost the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the construction industry.
