What is actually a concrete release agent?
A concrete release agent is a substance placed on the construction template before the concrete is put in order that the template does not stick to to the concrete surface after pouring, is not effortless to take down the form or impacts the complete of the concrete covering. Its principal role in the design and the concrete covering to create a motion picture that is going to be separated from the two is additionally known as an separation agent.
A water-based release agent is an important supplementary within the release agent and can modify the water-based release agent flow and levelling; its principal attribute is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent can be used in moulds and goods functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing cast items are not just to be able to let the form release to boost productivity and extend the life of the form use. And can make the merchandise clear, size qualified, and reduce the creation of scrap, which is an crucial additional vital to casts and products – Water-based Concrete Release Agent.
Concrete release agent plays an important role within modern building building; its main role is to form a layer of separation motion picture between the template and the concrete surface to ensure that the template does not stick to the concrete surface to ensure that it is simpler to dismantle the mould right after putting and to maintain the complete of the concrete covering. Here, we will unveil the kinds, qualities, utilization and program of concrete release agent in detail.
Sorts of concrete release agent
Concrete release agents can be divided into many types according to different grouping strategies, and the frequent grouping methods are as follows:
- According to the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete launch agent for tunnels and etc.
- According to the the composition of: it can be divided into water-based concrete release agents, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release agents, high-gloss concrete release agents and and so forth.
Qualities of Concrete release agent
A concrete release agent can also be known as a concrete remoteness agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete can be smoothly 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 substance motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low value and etc. However, not all kinds of concrete release agents with a variety of materials made of templates are suitable for different supplies 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 crucial construction auxiliary material, concrete release agent has the subsequent qualities:
Good separation performance: concrete release agent can form a dense remoteness movie between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete surface and facilitating the removing.
Excellent lubrication performance: concrete release agent has good lubricating overall performance, which can reduce the chaffing between the formwork and concrete area, decrease the resistance during pouring and enhance the construction efficiency.
Excellent anti-adhesion performance: concrete release agents can effectively stop the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.
Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can efficiently prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving the service life of the formwork.
Effortless 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 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 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 area, 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 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, preventing formwork from bonding with concrete and improving 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 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 development projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern building 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 development project and provide a strong guarantee for the growth of the development industry.
