What is actually a concrete release agent?
A concrete release agent is a substance placed on the building template prior to the concrete is poured so that the template does not stick to to the concrete surface following flowing, is just not easy to take apart the form or affects the complete of the concrete covering. Its principal role in the design and the concrete covering to create a movie that will probably be separated from the two can also be called an remoteness agent.
A water-based release agent is definitely an essential ancillary within the release agent and can modify the water-based release agent flow and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based form release agent is used in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods are not just so as to let the form release to boost productivity and lengthen the life of the mould make use of. And can make the item thoroughly clean, size qualified, and reduce the creation of scrap, which can be an essential additive vital to casts and products – concrete additive.
Concrete release agent plays an important role within modern building building; its main role would be to develop a layer of remoteness motion picture between the template and the concrete covering so that the template does not stick to the concrete area in order that it is much easier to take apart the cast right after putting and to maintain the end of the concrete surface. Here, we will present the types, qualities, utilization and use of concrete release agent in detail.
Types of concrete release agent
Concrete release agents can be divided into numerous sorts according to different grouping strategies, and the typical grouping strategies are as follows:
- According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete release agent for tunnels and and so forth.
- According to the the composition: it can be divided into water-based concrete release agents, oil-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the the effect of use: it can be divided into ordinary concrete release representatives, simple to remove concrete release agents, high-gloss concrete release brokers and so on.
Characteristics of Concrete release agent
A concrete release agent is additionally known as a concrete isolation agent or mould release lubricant. It is really a type of material coated on the inner wall of the formwork to play the role of lubrication and isolation so that the concrete may be smoothly detached from the formwork when taking down the formwork, and the form 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 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 representatives with a array of supplies made of templates are suitable for different components of the template and different building 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 following characteristics:
Good separation overall performance: concrete release agent can create a dense separation movie between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.
Excellent lubrication efficiency: concrete release agent has good lubrication performance, which can lower the chaffing between the formwork and concrete area, decrease the resistance during pouring and enhance the construction productivity.
Great anti-adhesion overall performance: concrete release representatives can successfully stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete surface when taking down the formwork.
Good waterproof efficiency: concrete release agent has good waterproof overall performance, which can efficiently avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving the service life of the formwork.
Simple 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 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 covering.
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 surface 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 covering, tools can be used appropriately to assist in the taking apart.
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 development 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, preventing 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 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 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 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 building projects.
In conclusion, concrete release agent, as an essential 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 building project and provide a strong guarantee for the growth of the building industry.
