What is actually a concrete release agent?
A concrete release agent is a compound applied to the development template prior to the concrete is added in order that the design does not stick to to the concrete covering following putting, isn’t simple to take down the cast or influences the finish of the concrete covering. Its main role within the template and the concrete area to form a film that will be separated from the two can also be known as an separation agent.
A water-based release agent is definitely an important supplementary inside the release agent and can change the water-based release agent stream and levelling; its principal feature is stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based form release agent can be used in moulds and items functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast items aren’t just so as to let the form release to enhance productivity and extend the life of the cast use. And can make the product clear, size qualified, and decrease the creation of scrap, which is an crucial additional important to moulds and goods – concrete release agent.
Concrete release agent plays an essential role inside modern building building; its main role is always to create a layer of remoteness movie between the template and the concrete area so that the template does not stick to to the concrete covering so that it is simpler to take down the mould after pouring and to maintain the end of the concrete area. Here, we will introduce the kinds, qualities, usage and use of concrete release agent at length.
Types of concrete release agent
Concrete release brokers can be divided into many sorts based on different classification techniques, and the common grouping strategies are the following:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete release agent for tunnels and and so forth.
- According to the composition: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release agents, easy-to-remove concrete release representatives, high-gloss concrete release brokers and etc.
Qualities of Concrete release agent
A concrete release agent is also known as a concrete isolation agent or mould release lubricant. It is actually a kind of compound coated on the inner wall of the formwork to play the part of lubricating and remoteness in order that the concrete could be easily detached from the formwork when taking down the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low price and so on. However, not all sorts of concrete release agents with a variety of materials made of templates are suitable for different components of the template and different development problems and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the following features:
Good separation overall performance: concrete release agent can create a dense remoteness film between the formwork and the concrete surface, effectively preventing the formwork from bonding with the concrete covering and facilitating the removing.
Great lubrication performance: concrete release agent has good lubrication performance, which can decrease the friction between the formwork and concrete area, decrease the resistance during pouring and enhance the construction effectiveness.
Good anti-adhesion efficiency: concrete release agents can successfully stop the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete area when taking apart the formwork.
Good waterproof performance: concrete release agent has good waterproof overall performance, which can successfully avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing 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 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 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 construction projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, preventing 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 surface 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 important construction auxiliary material, plays an indispensable role in modern construction 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 growth of the construction industry.
