What exactly is a concrete release agent?
A concrete release agent is a compound placed on the building design before the concrete is poured in order that the template will not stick to to the concrete covering following pouring, is just not effortless to take down the cast or influences the finish of the concrete area. Its principal role in the design and the concrete covering to develop a motion picture that will probably be separated from the two is also referred to as an remoteness agent.
A water-based release agent is an essential auxiliary within the release agent and can modify the water-based release agent circulation and levelling; its main attribute is definitely stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is used in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form products are not only so as to let the form release to boost productivity and lengthen the life of the form make use of. And can make the item thoroughly clean, size qualified, and decrease the generation of scrap, which can be an crucial supplementary essential to casts and products – concrete release agent.
Concrete release agent plays an crucial role inside modern building building; its primary role is always to develop a layer of remoteness film between the template and the concrete surface so that the template doesn’t stick to the concrete area so that it is easier to take apart the form after pouring and to maintain the complete of the concrete covering. Here, we will present the kinds, features, usage and use of concrete release agent in detail.
Sorts of concrete release agent
Concrete release brokers can be divided into numerous kinds according to different category strategies, and the typical category techniques are the following:
- According to the the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete discharge agent for tunnels and so on.
- According to the the composition of: it can be divided into water-based concrete release agents, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the the use effect: it can be divided into ordinary concrete release agents, simple 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 separation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the role of lubrication and isolation 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 conventional release material 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, simple to paint, low cost and etc. However, not all sorts of concrete release agents with a selection 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 suitable release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the following characteristics:
Good remoteness overall performance: concrete release agent can form a dense isolation movie between the formwork and the concrete surface, effectively stopping the formwork from bonding with the concrete area and facilitating the removing.
Good lubrication performance: concrete release agent has good lubrication overall performance, which can decrease the chaffing between the formwork and concrete covering, lower the resistance during pouring and enhance the construction productivity.
Good anti-adhesion overall performance: concrete release agents can effectively prevent the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can successfully prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving the service life of the formwork.
Easy 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 covering.
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 surface, tools can be used appropriately to assist in the dismantling.
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 agents can be used for formwork isolation, avoiding 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 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 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 brokers 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 essential construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the building industry.
