What is a concrete release agent?
A concrete release agent is actually a compound applied to the construction template just before the concrete is poured so that the template does not stick to the concrete area following putting, is not simple to take down the cast or influences the finish of the concrete covering. Its principal role within the template and the concrete covering to form a motion picture that is going to be separated from the two can also be referred to as an remoteness agent.
A water-based release agent is definitely an essential auxiliary in the release agent and can change the water-based release agent stream and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based cast release agent can be used in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing form products are not only to be able to let the form release to improve productivity and lengthen the life of the form use. And can make the item clean, size qualified, and lower the creation of scrap, which can be an important additive vital to forms and products – concrete release agent.
Concrete release agent plays an important role inside modern building building; its principal role would be to develop a layer of isolation movie between the template and the concrete surface in order that the template does not adhere to the concrete surface to ensure that it is easier to dismantle the form following pouring and to maintain the finish of the concrete area. Here, we will present the kinds, features, usage and application of concrete release agent at length.
Sorts of concrete release agent
Concrete release agents can be divided into numerous kinds based on different classification methods, and the typical category methods are as follows:
- According to the 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 and so forth.
- According to the formula of: it can be divided into water-based concrete release agents, petroleum-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release agents and and so forth.
Qualities of Concrete release agent
A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is really a type of substance coated on the inner wall of the formwork to play the function of lubricating and separation so that the concrete may be smoothly detached from the formwork when taking apart the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low price and etc. However, not all types of concrete release agents with a selection of supplies made of templates are suitable for different components of the template and different development conditions 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 subsequent qualities:
Good isolation efficiency: concrete release agent can form a dense isolation motion picture between the formwork and the concrete area, successfully avoiding the formwork from bonding with the concrete surface and facilitating the demolding.
Excellent lubrication efficiency: concrete release agent has good lubricating efficiency, which can lower the friction between the formwork and concrete covering, decrease the resistance during pouring and improve the construction effectiveness.
Excellent anti-adhesion performance: concrete release representatives can effectively stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.
Great waterproof efficiency: 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.
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 down 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 covering, tools can be used appropriately to assist in the taking down.
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 brokers 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 surface, 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 boost 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 development projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right kind, 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 advancement of the building industry.
