What is actually a concrete release agent?
A concrete release agent is actually a substance placed on the construction design before the concrete is poured so the template doesn’t stick to to the concrete covering right after pouring, isn’t effortless to take down the cast or influences the complete of the concrete surface. Its main role within the template and the concrete area to create a motion picture that is going to be separated from the two can also be known as an separation agent.
A water-based release agent is an essential auxiliary within the release agent and can modify the water-based release agent circulation and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based mould release agent can be used in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing mould items are not only so as to let the mould release to enhance productivity and lengthen the life of the cast make use of. And can make the merchandise clean, size qualified, and reduce the generation of scrap, which can be an essential supplementary essential to moulds and goods – concrete additive.
Concrete release agent plays an essential role in modern building development; its main role is always to form a layer of isolation film between the design and the concrete surface in order that the template does not stick to the concrete surface to ensure that it is simpler to take down the mould right after flowing and to maintain the complete of the concrete covering. Here, we will introduce the types, qualities, use and program of concrete release agent at length.
Types of concrete release agent
Concrete release representatives can be divided into numerous types in accordance with different grouping strategies, and the typical category strategies are the following:
- According to the the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete launch agent for tunnels and etc.
- According to the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the effect of use: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release representatives, high-gloss concrete release representatives and etc.
Characteristics 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 compound coated on the inner wall of the formwork to play the role of lubrication and isolation to ensure that the concrete can be easily detached from the formwork when taking apart the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the conventional release material 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, simple to paint, low value and so on. However, not all kinds of concrete release agents with a array of supplies made of templates are suitable for different materials of the template and different development 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 qualities:
Good remoteness efficiency: concrete release agent can create a dense separation motion picture between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.
Excellent lubrication overall performance: concrete release agent has good lubrication overall performance, which can reduce the chaffing between the formwork and concrete covering, reduce the resistance during pouring and enhance the construction productivity.
Great anti-adhesion performance: concrete release representatives can efficiently stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete area when taking down the formwork.
Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can effectively prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.
Easy 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 dismantling 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 surface, tools can be used appropriately to assist in the taking down.
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 construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, avoiding 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 area, 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 boost 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 development projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern building 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 building project and provide a strong guarantee for the development of the construction industry.
