What exactly is a concrete release agent?
A concrete release agent is actually a substance put on the construction template before the concrete is added in order that the design will not adhere to the concrete surface following flowing, is just not simple to dismantle the cast or impacts the finish of the concrete area. Its principal role in the template and the concrete area to create a movie that will be separated from the two can also be called an isolation agent.
A water-based release agent is surely an crucial supplementary in the release agent and can change the water-based release agent circulation and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based mould release agent is utilized in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing mould items aren’t just to be able to let the form release to improve productivity and prolong the life of the mould use. And can make the product clean, size qualified, and decrease the creation of scrap, that is an crucial supplementary important to casts and products – concrete release agent.
Concrete release agent plays an important role within modern building construction; its principal role is to develop a layer of remoteness film between the template and the concrete surface in order that the template does not adhere to the concrete area to ensure that it is much easier to dismantle the mould right after pouring and to maintain the finish of the concrete area. Here, we will unveil the kinds, characteristics, use and use of concrete release agent in detail.
Types of concrete release agent
Concrete release agents can be divided into many types based on different classification methods, and the frequent grouping strategies are as follows:
- According to the scope of use: it can be divided into concrete release agent for building, 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 representatives, petroleum-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the use effect: it can be divided into ordinary concrete release agents, simple to remove concrete release agents, high-gloss concrete release representatives and etc.
Characteristics 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 sort of compound coated on the inner wall of the formwork to play the function of lubrication and separation to ensure that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the standard release substance 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, simple to paint, low price and etc. However, not all kinds of concrete release agents with a array of materials 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 suitable release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the following features:
Good separation overall performance: concrete release agent can develop a dense isolation motion picture between the formwork and the concrete surface, successfully preventing the formwork from bonding with the concrete area and facilitating the removing.
Great lubrication efficiency: concrete release agent has good lubricating efficiency, which can decrease the chaffing between the formwork and concrete area, lower the resistance during pouring and improve the construction effectiveness.
Great anti-adhesion overall performance: concrete release representatives can successfully stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete area when taking down the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can successfully avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing 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 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 taking down.
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 building of a reinforced concrete structure, concrete release brokers 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 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 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 representatives 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 kind, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the development industry.
