What is a concrete release agent?
A concrete release agent is a substance placed on the development template prior to the concrete is added so that the design does not stick to to the concrete surface after flowing, is just not effortless to take down the form or impacts the complete of the concrete surface. Its primary role in the design and the concrete surface to form a movie that will probably be separated from the two is also referred to as an isolation agent.
A water-based release agent is definitely an crucial ancillary within the release agent and can alter the water-based release agent circulation and levelling; its primary feature is stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based mould release agent is used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould goods are not just in order to let the mould release to improve productivity and extend the life of the cast utilize. And can make the merchandise clear, size qualified, and lower the technology of scrap, which can be an crucial additive vital to moulds and items – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role inside modern building development; its main role is always to develop a layer of remoteness film between the design and the concrete area so that the template will not stick to the concrete area so that it is simpler to dismantle the mould after putting and to maintain the complete of the concrete surface. Here, we will introduce the types, features, use and application of concrete release agent in more detail.
Kinds of concrete release agent
Concrete release representatives can be divided into several types based on different classification techniques, and the frequent category strategies are as follows:
- According to the the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
- According to the composition of: it can be divided into water-based concrete release representatives, petroleum-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the the use effect: it can be divided into ordinary concrete release agents, an easy task to remove concrete release brokers, high-gloss concrete release agents and and so forth.
Qualities of Concrete release agent
A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is actually a kind of substance coated on the inner wall of the formwork to play the part of lubrication and isolation in order that the concrete could be easily detached from the formwork when taking apart the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the conventional 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, effortless to paint, low cost and so on. However, not all kinds of concrete release agents with a selection of materials made of templates are suitable for different supplies of the template and different building 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 following characteristics:
Good separation efficiency: concrete release agent can develop a dense separation motion picture between the formwork and the concrete surface, successfully preventing the formwork from bonding with the concrete area and facilitating the removing.
Excellent lubrication efficiency: concrete release agent has good lubrication efficiency, which can reduce the chaffing between the formwork and concrete surface, decrease the resistance during pouring and improve the construction productivity.
Excellent anti-adhesion performance: concrete release agents can effectively avoid the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when taking apart the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof performance, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving the service life of the formwork.
Easy 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 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 area, tools can be used appropriately to assist in the taking apart.
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 building 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, 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 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 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 building projects.
In conclusion, concrete release agent, as an important 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the construction industry.
