What is a concrete release agent?
A concrete release agent is a compound placed on the construction template prior to the concrete is put in order that the template doesn’t stick to the concrete surface following pouring, is not effortless to take apart the cast or impacts the finish of the concrete covering. Its main role in the template and the concrete area to create a film that will probably be separated from the two can also be known as an separation agent.
A water-based release agent is an important ancillary within the release agent and can change the water-based release agent circulation and levelling; its main characteristic is definitely stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based mould release agent can be used in moulds and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form items are not just so as to let the cast release to enhance productivity and extend the life of the mould make use of. And can make the product thoroughly clean, size qualified, and lower the creation of scrap, which is an important supplementary important to forms and items – concrete additive.
Concrete release agent plays an essential role within modern building construction; its principal role is to develop a layer of separation movie between the template and the concrete covering in order that the template doesn’t adhere to the concrete area to ensure that it is simpler to take apart the mould after flowing and to maintain the end of the concrete covering. Here, we will present the sorts, characteristics, utilization and application of concrete release agent in more detail.
Types of concrete release agent
Concrete release representatives can be divided into several kinds in accordance with different grouping strategies, and the frequent classification methods 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, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the the effect of use: it can be divided into ordinary concrete release agents, easy-to-remove concrete release agents, high-gloss concrete release representatives 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 really a type of substance coated on the inner wall of the formwork to play the function of lubrication and separation so that the concrete could be smoothly detached from the formwork when taking down the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the traditional 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, effortless to paint, low price and so on. However, not all sorts of concrete release representatives with a array of components made of templates are suitable for different supplies of the template and different development circumstances 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 subsequent characteristics:
Good isolation efficiency: concrete release agent can create a dense remoteness movie between the formwork and the concrete surface, successfully avoiding the formwork from bonding with the concrete area and facilitating the removing.
Great lubrication overall performance: concrete release agent has good lubricating performance, which can decrease the friction between the formwork and concrete surface, decrease the resistance during pouring and improve the construction productivity.
Great anti-adhesion efficiency: concrete release agents can efficiently prevent the formwork from bonding with the concrete surface, 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 successfully prevent moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving 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 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 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 covering, tools can be used appropriately to assist in the taking down.
Clean up the template: after taking apart 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 brokers 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 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 area 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 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 construction projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right type, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the development project and provide a strong guarantee for the development of the development industry.
