What exactly is a concrete release agent?
A concrete release agent is a substance placed on the construction design before the concrete is put in order that the template does not stick to the concrete covering following putting, is just not easy to dismantle the cast or influences the finish of the concrete area. Its principal role in the template and the concrete area to create a movie that will be separated from the two is additionally called an separation agent.
A water-based release agent is definitely an crucial auxiliary inside the release agent and can change the water-based release agent circulation and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based mould release agent can be used in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items aren’t just to be able to let the cast release to enhance productivity and extend the life of the cast utilize. And can make the product thoroughly clean, size qualified, and reduce the creation of scrap, that is an crucial additive vital to moulds and goods – Water-based Concrete Release Agent.
Concrete release agent plays an important role inside modern building development; its principal role is to develop a layer of remoteness motion picture between the template and the concrete area so that the design does not adhere to the concrete area in order that it is much easier to dismantle the form right after flowing and to maintain the end of the concrete covering. Here, we will introduce the types, qualities, usage and application of concrete release agent in more detail.
Kinds of concrete release agent
Concrete release agents can be divided into many types based on different category methods, and the common grouping techniques 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 emission agent for tunnels and and so forth.
- According to the composition of: it can be divided into water-based concrete release agents, petroleum-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the the use effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release representatives, high-gloss concrete release brokers and and so forth.
Characteristics of Concrete release agent
A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the function of lubricating and separation so that the concrete could be smoothly detached from the formwork when dismantling 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 surface, no corrosion of the template, simple to paint, low value and etc. However, not all types of concrete release representatives with a selection of materials made of templates are suitable for different components of the template and different construction circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the next characteristics:
Good separation efficiency: concrete release agent can form a dense remoteness film between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the removing.
Good lubrication efficiency: concrete release agent has good lubrication overall performance, which can lower the chaffing between the formwork and concrete covering, reduce the resistance during pouring and boost the construction productivity.
Good anti-adhesion efficiency: concrete release agents can effectively stop the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete area when taking apart the formwork.
Good waterproof efficiency: concrete release agent has good waterproof overall performance, 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.
Effortless to use and safe: concrete release agent is effortless 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 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 surface gradually. In case of tight bonding between the formwork and the concrete area, 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 building of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing formwork from bonding with concrete and enhancing 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 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 crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the construction industry.
