What is actually a concrete release agent?
A concrete release agent is a material placed on the development template just before the concrete is put so that the template doesn’t stick to the concrete surface after flowing, isn’t effortless to take down the cast or influences the finish of the concrete area. Its principal role within the template and the concrete covering to form a movie that will be separated from the two is also referred to as an isolation agent.
A water-based release agent is surely an crucial supplementary inside the release agent and can alter the water-based release agent circulation and levelling; its principal characteristic is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based cast release agent is used in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing mould products are not just so as to let the form release to improve productivity and prolong the life of the cast use. And can make the product thoroughly clean, size qualified, and decrease the creation of scrap, that is an essential additive vital to forms and items – concrete additive.
Concrete release agent plays an important role within modern building development; its main role is to develop a layer of remoteness film between the template and the concrete surface so that the design will not stick to the concrete surface in order that it is much easier to dismantle the mould right after flowing and to maintain the end of the concrete covering. Here, we will present the sorts, features, use and program of concrete release agent in more detail.
Types of concrete release agent
Concrete release brokers can be divided into numerous types according to different category strategies, and the typical grouping strategies are the subsequent:
- According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and etc.
- According to the composition of: it can be divided into water-based concrete release representatives, oil-based concrete release representatives, silicone oil concrete release agents, etc.
- According to the the use effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release representatives and and so forth.
Qualities 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 type of material coated on the inner wall of the formwork to play the function of lubricating and isolation to ensure that the concrete could be easily detached from the formwork when taking apart the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and so on. However, not all types of concrete release representatives with a variety of materials made of templates are suitable for different materials of the template and different development conditions and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the subsequent characteristics:
Good separation performance: concrete release agent can create a dense separation motion picture between the formwork and the concrete covering, effectively preventing the formwork from bonding with the concrete area and facilitating the removing.
Good lubrication overall performance: concrete release agent has good lubricating efficiency, which can decrease the rubbing between the formwork and concrete covering, decrease the resistance during pouring and boost the construction effectiveness.
Excellent anti-adhesion performance: concrete release brokers can efficiently prevent the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete area when taking apart the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively stop 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 easy 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 dismantling the formwork, the connectors at the edge of the formwork should be dismantled first, and then the surface 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 covering, tools can be used appropriately to assist in the taking apart.
Clean up the template: after dismantling 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 development of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 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 development projects.
In conclusion, concrete release agent, as an crucial 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 construction project and provide a strong guarantee for the advancement of the development industry.
