What is actually a concrete release agent?
A concrete release agent is actually a substance placed on the development template just before the concrete is put in order that the template will not adhere to the concrete covering following flowing, is just not effortless to dismantle the mould or affects the complete of the concrete covering. Its primary role in the template and the concrete area to develop a film that will probably be separated from the two can also be referred to as an remoteness agent.
A water-based release agent is definitely an essential supplementary inside the release agent and can change the water-based release agent circulation and levelling; its primary feature is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based cast release agent is utilized in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing cast products aren’t just in order to let the mould release to enhance productivity and lengthen the life of the mould use. And can make the merchandise clean, size qualified, and lower the creation of scrap, which is an essential supplementary essential to casts and products – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role in modern building construction; its primary role would be to form a layer of isolation motion picture between the design and the concrete surface to ensure that the template doesn’t stick to the concrete surface so that it is much easier to dismantle the cast following flowing and to maintain the end of the concrete area. Here, we will introduce the types, qualities, utilization and program of concrete release agent at length.
Types of concrete release agent
Concrete release agents can be divided into several sorts in accordance with different category techniques, and the common category methods are as follows:
- According to the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and etc.
- According to the formula of: it can be divided into water-based concrete release representatives, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the use effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release brokers, high-gloss concrete release representatives and and so forth.
Qualities of Concrete release agent
A concrete release agent is additionally called a concrete separation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the part of lubricating and isolation so that the concrete could be easily detached from the formwork when taking down the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the traditional release materials 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 value and so on. However, not all kinds of concrete release agents with a array of supplies made of templates are suitable for different components of the template and different building circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the following features:
Good separation efficiency: concrete release agent can form a dense separation movie between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete area and facilitating the demolding.
Good lubrication overall performance: concrete release agent has good lubrication overall performance, which can decrease the friction between the formwork and concrete covering, lower the resistance during pouring and enhance the construction productivity.
Good anti-adhesion efficiency: concrete release brokers can effectively avoid the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete area when dismantling the formwork.
Good waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing the service life of the formwork.
Effortless 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 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 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 area gradually. In case of tight bonding between the formwork and the concrete covering, tools can be used appropriately to assist in the taking apart.
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 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, 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 surface 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 enhance 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 construction projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the construction industry.
