What exactly is a concrete release agent?
A concrete release agent is a compound put on the building design prior to the concrete is poured so that the template will not adhere to the concrete covering after putting, isn’t easy to dismantle the form or affects the complete of the concrete surface. Its main role in the design and the concrete area to form a film that will probably be separated from the two is also called an separation agent.
A water-based release agent is an important auxiliary inside the release agent and can alter the water-based release agent flow and levelling; its primary characteristic is definitely stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based mould release agent is used in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form goods are not just in order to let the cast release to boost productivity and extend the life of the cast utilize. And can make the product clean, size qualified, and lower the technology of scrap, which can be an crucial additive essential to moulds and goods – concrete additive.
Concrete release agent plays an important role in modern building building; its primary role would be to develop a layer of separation motion picture between the design and the concrete surface so that the template doesn’t adhere to the concrete covering in order that it is easier to dismantle the cast after putting and to maintain the complete of the concrete area. Here, we will present the sorts, characteristics, use and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release representatives can be divided into numerous kinds in accordance with different classification strategies, and the frequent grouping techniques are as follows:
- 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 etc.
- According to the the composition of: it can be divided into water-based concrete release brokers, petroleum-based concrete release agents, silicone oil concrete release agents, etc.
- According to the utilization effect: it can be divided into ordinary concrete release agents, simple to remove concrete release brokers, high-gloss concrete release agents and so on.
Features of Concrete release agent
A concrete release agent is additionally referred to as a concrete separation agent or mould release lubricant. It is really a sort of material coated on the inner wall of the formwork to play the part of lubrication and separation so that the concrete may be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low cost and etc. However, not all kinds of concrete release agents with a selection of supplies made of templates are suitable for different components 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 next characteristics:
Good isolation performance: concrete release agent can form a dense remoteness film between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.
Great lubrication efficiency: concrete release agent has good lubrication performance, which can lower the friction between the formwork and concrete covering, reduce the resistance during pouring and enhance the construction efficiency.
Great anti-adhesion overall performance: concrete release brokers can effectively avoid the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can efficiently avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing the service life of the formwork.
Easy 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 oil-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 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 building 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, avoiding 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 covering 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 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 construction projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right type, 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 advancement of the building industry.
