What exactly is a concrete release agent?
A concrete release agent is actually a material put on the building template just before the concrete is put in order that the template does not adhere to the concrete area after putting, isn’t effortless to take down the form or affects the end of the concrete surface. Its primary role in the design and the concrete area to develop a motion picture that will be separated from the two is also called an isolation agent.
A water-based release agent is surely an important auxiliary within 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 lower the price of raw materials. A water-based form release agent is utilized in moulds and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast goods aren’t just to be able to let the form release to improve productivity and extend the life of the form utilize. And can make the item clean, size qualified, and lower the creation of scrap, which can be an essential supplementary important to forms and goods – concrete additive.
Concrete release agent plays an important role within modern building building; its primary role is always to develop a layer of remoteness movie between the design and the concrete covering in order that the template will not stick to to the concrete surface in order that it is simpler to dismantle the mould after pouring and to maintain the complete of the concrete area. Here, we will present the sorts, characteristics, use and use of concrete release agent at length.
Kinds of concrete release agent
Concrete release representatives can be divided into numerous sorts based on different grouping techniques, and the common classification techniques 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 discharge agent for tunnels and and so forth.
- According to the formula of: it can be divided into water-based concrete release representatives, petroleum-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the use effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release representatives, high-gloss concrete release representatives and etc.
Qualities of Concrete release agent
A concrete release agent can also be referred to as a concrete separation agent or mould release lubricant. It is a type of material coated on the inner wall of the formwork to play the function of lubricating and remoteness to ensure that the concrete may be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete area, no corrosion of the template, easy to paint, low cost and so on. However, not all sorts of concrete release representatives with a array of supplies made of templates are suitable for different materials 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 important construction auxiliary material, concrete release agent has the following features:
Good separation overall performance: concrete release agent can form a dense remoteness movie between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete area and facilitating the demolding.
Great lubrication performance: concrete release agent has good lubrication efficiency, which can decrease the rubbing between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction efficiency.
Good anti-adhesion performance: concrete release representatives can effectively avoid the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete surface when dismantling the formwork.
Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can efficiently stop moisture from penetrating between the formwork and concrete, avoiding 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 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 covering.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When dismantling 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 surface gradually. In case of tight bonding between the formwork and the concrete area, 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, stopping 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 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 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 building projects.
In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right kind, 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 development of the building industry.
