What is actually a concrete release agent?
A concrete release agent is a material applied to the building design just before the concrete is poured so the design will not stick to to the concrete covering following flowing, is not simple to take apart the cast or influences the end of the concrete area. Its principal role in the template and the concrete surface to form a motion picture that is going to be separated from the two is also known as an remoteness agent.
A water-based release agent is an important ancillary in the release agent and can modify the water-based release agent stream and levelling; its principal attribute is stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based form release agent is used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods are not just so as to let the cast release to enhance productivity and extend the life of the form utilize. And can make the merchandise clear, size qualified, and reduce the creation of scrap, that is an crucial additional important to forms and products – concrete release agent.
Concrete release agent plays an important role within modern building building; its primary role is to develop a layer of isolation film between the template and the concrete area in order that the template does not stick to the concrete surface so that it is easier to take apart the form following putting and to maintain the finish of the concrete surface. Here, we will unveil the types, characteristics, usage and use of concrete release agent in detail.
Types of concrete release agent
Concrete release brokers can be divided into numerous sorts based on different category strategies, and the typical grouping strategies are as follows:
- According to the the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
- According to the composition: it can be divided into water-based concrete release agents, oil-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the use effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release representatives, high-gloss concrete release brokers and etc.
Characteristics of Concrete release agent
A concrete release agent is additionally known as a concrete remoteness agent or mould release lubricant. It is actually a type of material coated on the inner wall of the formwork to play the function of lubrication and remoteness to ensure that the concrete could be effortlessly detached from the formwork when taking down the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete area, no corrosion of the template, easy to paint, low price and etc. However, not all sorts of concrete release brokers with a array of materials made of templates are suitable for different supplies of the template and different construction problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the following qualities:
Good remoteness performance: concrete release agent can create a dense remoteness movie between the formwork and the concrete covering, successfully avoiding the formwork from bonding with the concrete surface and facilitating the removing.
Excellent lubrication efficiency: concrete release agent has good lubricating performance, which can reduce the friction between the formwork and concrete area, reduce the resistance during pouring and enhance the construction effectiveness.
Good anti-adhesion overall performance: concrete release agents can successfully stop the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete area when taking down the formwork.
Good waterproof overall performance: concrete release agent has good waterproof efficiency, which can effectively avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.
Simple 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 surface.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking apart 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 surface 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 development of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 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 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 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 type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the building industry.
