What is actually a concrete release agent?
A concrete release agent is a material put on the construction template prior to the concrete is added in order that the template doesn’t stick to to the concrete surface right after pouring, is not simple to dismantle the cast or influences the complete of the concrete area. Its principal role in the template and the concrete covering to create a film that is going to be separated from the two can also be called an separation agent.
A water-based release agent is an important auxiliary in the release agent and can change the water-based release agent flow and levelling; its primary characteristic is stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based mould release agent can be used in casts and items functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing mould products are not only so as to let the form release to boost productivity and lengthen the life of the mould use. And can make the merchandise thoroughly clean, size qualified, and reduce the generation of scrap, which is an important additive vital to moulds and goods – concrete additive.
Concrete release agent plays an crucial role within modern building building; its principal role is to develop a layer of separation film between the template and the concrete covering to ensure that the design does not stick to the concrete surface to ensure that it is easier to dismantle the form following flowing and to maintain the end of the concrete covering. Here, we will unveil the sorts, qualities, usage and program of concrete release agent in detail.
Kinds of concrete release agent
Concrete release agents can be divided into many types in accordance with different classification strategies, and the common category techniques are the following:
- According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete launch agent for tunnels and and so forth.
- According to the the composition: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the utilization effect: it can be divided into ordinary concrete release agents, simple to remove concrete release representatives, high-gloss concrete release agents and so on.
Qualities of Concrete release agent
A concrete release agent is also called a concrete separation agent or mould release lubricant. It is actually a kind of substance coated on the inner wall of the formwork to play the function of lubrication and separation so that the concrete could be effortlessly 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 positive aspects of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low price and etc. However, not all kinds of concrete release brokers with a selection of components made of templates are suitable for different materials of the template and different construction problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the next features:
Good remoteness overall performance: concrete release agent can create a dense remoteness film between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete surface and facilitating the demolding.
Good lubrication performance: concrete release agent has good lubrication performance, which can reduce the friction between the formwork and concrete covering, reduce the resistance during pouring and enhance the construction effectiveness.
Excellent anti-adhesion efficiency: concrete release representatives can effectively prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.
Great waterproof overall performance: concrete release agent has good waterproof overall performance, which can effectively stop 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.
Simple 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 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 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 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 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 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 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 kind, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the development project and provide a strong guarantee for the development of the building industry.
