What exactly is a concrete release agent?
A concrete release agent is a material put on the building template prior to the concrete is added so the design doesn’t stick to the concrete surface right after putting, isn’t easy to take down the cast or affects the complete of the concrete surface. Its main role in the design and the concrete covering to form a movie that is going to be separated from the two can also be called an separation agent.
A water-based release agent is an essential ancillary within the release agent and can change the water-based release agent flow and levelling; its principal characteristic is definitely stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based mould release agent is used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing cast items are not only to be able to let the cast release to enhance productivity and extend the life of the mould utilize. And can make the item clean, size qualified, and lower the creation of scrap, which can be an crucial additional important to casts and products – Water-based Concrete Release Agent.
Concrete release agent plays an essential role in modern building building; its primary role would be to develop a layer of remoteness motion picture between the template and the concrete area so that the template does not stick to to the concrete surface in order that it is simpler to take apart the mould right after pouring and to maintain the complete of the concrete covering. Here, we will unveil the kinds, qualities, utilization and program of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release representatives can be divided into many sorts according to different grouping strategies, and the common grouping methods are the subsequent:
- According to the the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and etc.
- According to the formula of: it can be divided into water-based concrete release brokers, petroleum-based concrete release agents, silicone oil concrete release agents, etc.
- According to the the use effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release brokers, high-gloss concrete release agents and and so forth.
Characteristics of Concrete release agent
A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is a sort of material coated on the inner wall of the formwork to play the role of lubrication and separation in order that the concrete could be easily detached from the formwork when taking apart the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low price and and so forth. However, not all sorts of concrete release representatives with a selection of supplies made of templates are suitable for different supplies of the template and different development problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the next features:
Good separation performance: concrete release agent can form a dense separation film between the formwork and the concrete surface, efficiently 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 decrease the chaffing between the formwork and concrete area, lower the resistance during pouring and improve the construction productivity.
Excellent anti-adhesion efficiency: concrete release representatives can successfully avoid the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.
Great waterproof efficiency: concrete release agent has good waterproof efficiency, which can successfully avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.
Easy 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 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 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 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 building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 covering and improve 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 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 development project and provide a strong guarantee for the development of the construction industry.
