What is a concrete release agent?
A concrete release agent is actually a compound applied to the development template just before the concrete is added so the template will not stick to the concrete area right after putting, is just not easy to take apart the cast or impacts the end of the concrete surface. Its primary role inside the design and the concrete covering to create a movie that will probably be separated from the two is also known as an remoteness agent.
A water-based release agent is surely an important ancillary within the release agent and can alter the water-based release agent flow and levelling; its primary characteristic is actually stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based form release agent is used in casts and products functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods are not only in order to let the mould release to enhance productivity and extend the life of the cast use. And can make the product thoroughly clean, size qualified, and lower the creation of scrap, which can be an important additive essential to casts and goods – concrete release agent.
Concrete release agent plays an important role within modern building building; its principal role would be to create a layer of isolation motion picture between the design and the concrete covering in order that the template does not stick to to the concrete surface so that it is much easier to dismantle the cast after putting and to maintain the finish of the concrete area. Here, we will present the types, features, usage and program of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release brokers can be divided into numerous types according to different classification strategies, and the typical classification methods are the following:
- According to the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete emission agent for tunnels and etc.
- According to the composition of: it can be divided into water-based concrete release agents, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release brokers, high-gloss concrete release brokers and and so forth.
Features of Concrete release agent
A concrete release agent is additionally referred to 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 remoteness so that the concrete can be smoothly detached from the formwork when taking apart the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low price and and so forth. However, not all kinds of concrete release brokers with a array of components made of templates are suitable for different components of the template and different building circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the subsequent characteristics:
Good separation efficiency: concrete release agent can form a dense remoteness motion picture between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete surface and facilitating the demolding.
Good lubrication efficiency: concrete release agent has good lubrication overall performance, which can lower the rubbing between the formwork and concrete surface, reduce the resistance during pouring and improve the construction productivity.
Excellent anti-adhesion efficiency: concrete release representatives can successfully stop the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.
Good waterproof performance: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing the service life of the formwork.
Effortless 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 down 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 covering, tools can be used appropriately to assist in the taking apart.
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 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, preventing formwork from bonding with concrete and improving 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 area and enhance 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 building 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 construction project and provide a strong guarantee for the growth of the building industry.
