What is a concrete release agent?
A concrete release agent is definitely a compound put on the development template prior to the concrete is put so that the template does not stick to to the concrete surface following pouring, is just not simple to take down the mould or affects the finish of the concrete covering. Its primary role within the template and the concrete area to develop a movie that is going to be separated from the two can also be referred to as an isolation agent.
A water-based release agent is surely an important auxiliary in the release agent and can modify the water-based release agent flow and levelling; its main characteristic is actually stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based mould release agent is utilized in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing mould products aren’t just so as to let the form release to enhance productivity and extend the life of the cast utilize. And can make the product clean, size qualified, and decrease the creation of scrap, that is an important additional vital to forms and products – Water-based Concrete Release Agent.
Concrete release agent plays an essential role within modern building development; its primary role is to form a layer of remoteness movie between the template and the concrete area in order that the template will not adhere to the concrete area so that it is easier to take apart the mould after flowing and to maintain the complete of the concrete area. Here, we will present the types, characteristics, use and use of concrete release agent in detail.
Types of concrete release agent
Concrete release brokers can be divided into numerous sorts according to different classification methods, and the common grouping techniques are the subsequent:
- According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and so on.
- According to the formula of: it can be divided into water-based concrete release representatives, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the effect of use: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release agents, high-gloss concrete release agents and so on.
Characteristics of Concrete release agent
A concrete release agent is also known as a concrete remoteness agent or mould release lubricant. It is actually a sort of compound coated on the inner wall of the formwork to play the role of lubricating and separation to ensure that the concrete may be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low price and and so forth. However, not all sorts of concrete release agents with a array of materials made of templates are suitable for different supplies of the template and different construction conditions 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 qualities:
Good isolation efficiency: concrete release agent can create a dense separation motion picture between the formwork and the concrete surface, effectively preventing the formwork from bonding with the concrete surface and facilitating the removing.
Great lubrication performance: concrete release agent has good lubricating overall performance, which can decrease the friction between the formwork and concrete covering, lower the resistance during pouring and enhance the construction effectiveness.
Good anti-adhesion efficiency: concrete release representatives can efficiently prevent the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when taking apart the formwork.
Good waterproof overall performance: concrete release agent has good waterproof performance, 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 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 petroleum-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 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 area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the dismantling.
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 construction projects, mainly including the following aspects:
Reinforced concrete structure: In the construction 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 surface 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 boost 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 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 building project and provide a strong guarantee for the growth of the construction industry.
